EdenPURE GEN4 or iHeater 1500

When it comes to space heaters there are many options to choose from online and in big box stores. Generally, space heaters are designed and used to deliver spot heating to a specific small area, or on a person. Examples would be placing a space heater under a desk to warm a person's legs and feet, or placing the heater in a small room, like a bathroom for extra heat.

Typically we think of a space heater as a small inexpensive unit with metal ribbons or coils inside of it that heat up (kind of like a toaster) to radiate heat. Others are designed to have air flow over the coils to deliver fan forced warm air. Most of the inexpensive units are made with plastic components and are not designed to last very long.

Other units are more expensive and can last years or decades. But are they really space heaters, or something more? I believe they are actually something a bit more than a space heater.

You have undoubtedly seen the ads and infomercials for the wonderfully built, hand-crafted, wood cases that can heat a whole room. I am referring to the EdenPURE GEN4 models. There is a similar unit that does the same job called an iHeater 1500. The question is; do they work and which is best?

The answer is they do work when used correctly and the decision point on which is best is really personal preference. What is preferred is whether you like infrared heat technology that is solid state or quartz tube, or if you like heat lamp bulb technology.

The EdenPURE units have generally used Sylvania heat lamp bulbs in the past. The primary issue with these units is the bulbs burning out and needing replaced. Recently the EdenPURE GEN4 (approximately $397) has been improved to include infrared technology that is basically a glass quartz tube that heats up a metal cylinder. There are three of these quartz tube/cylinder combinations. These glass quartz tubes can also burn out and need replacing. The three tube/cylinder units are built into a rounded triangular housing through which fan-forced air moves. The fact that there are three of them built into a housing would make it hard to detect if any of them are burnt out or not. Ambient room air enters the rear of the unit, moves through the quartz tube cylinder housing, and exits the top front of the EdenPURE unit and warm air fills the space it is located in.

The Eden Pure Gen4 uses three Sylvania infrared quartz bulbs that have an advertised life expectancy of 10-15 years for the unit, 20,000 hours for the bulbs. They cost approximately $50-$60 to replace.
The iHeater uses a solid state copper heat chamber with a lifetime warranty and claims it can last 9 years of continuous use, or 15 winter seasons.

The iHeater 1500 (approximately $379) uses a solid state copper heating chamber infrared system that contains no bulbs or glass quartz tubes. It comes with a lifetime filter that can be removed and cleaned with no tools. The iHeater 1500 also utilizes fan-forced air through its heating chamber. Ambient room air enters the rear of the unit, moves through the solid state infrared copper heating chamber and exits the top front of the iHeater 1500 and warm air fills the space it is located in.

Both units have similarities.

Both units have enclosed housings that are cool to the touch. They are both portable and can be placed on casters to roll. They both have digital controls and a remote control. They are both safe for kids and pets and have an overheat sensor to turn the unit off at a certain temperature.

Both units have been modified for enhanced performance. The EdenPURE GEN4 runs quieter and has an improved fan, an improved thermostat, and quartz infrared bulbs. The iHeater 1500 has improved its thermostat and relocated it within the unit away from the heat chamber, improved the seals of the unit, and built it to tighter specs improving the force of the air flow and the heating of the air. Both units have a lifetime air filter that can be easily removed and cleaned. And finally, both units claim to heat a room evenly, wall to wall, floor to ceiling lowering your heating bill.

Both units have differences.

The EdenPURE GEN4 has bulbs that need replaced and you don't know when one or more of them burn out. If even one burns out the unit must work longer to produce the same heat lowering its efficiency. The iHeater 1500 uses no bulbs and places a lifetime warranty on its solid state heat chamber. Also, the EdenPURE GEN4 advertises an approximate BTU of 5,000 covering 1,000 square feet. The iHeater 1500 advertises that it covers up to 1,500 square feet at about 5,125 BTUs. The iHeater also has a safety feature that will turn off the unit if it is tipped. Lastly, the units retail pricing are about $18 apart, the EdenPURE GEN4 at $397 and the iHeater 1500 at $379. You can find both of them offered at various discounts.
An internet search yielded one reputable negative comment with one of the units.

A report was located in Consumer Reports about the EdenPURE GEN4 1000 having a melting, burning plastic problem. The link for more information is

Now that the units have been identified by general operation, heat chamber technology, similarities, differences, and pricing, how do they save money?

It is simple, 100% of the heated air produced by the unit is used within the space the unit is located. The heat evenly heats a room wall to wall and floor to ceiling. This is not the case with your furnace within you home. Most homes using a furnace are only using 50% of the warm fan-forced air. About 10% of your furnace heat is escaping up the chimney. Additional heat loss happens at the joints and connections in the tin and duct work of your furnace and registers. If any of that duct work is on an exterior wall heat is radiated into the wall like a heat sink and can be seen with a thermal camera escaping through the wall to the outside of your home. Drafty windows and other such home improvement issues contribute additional heat loss.

When a device like the iHeater 1500 or EdenPURE GEN4 is used 100% of the heated air produced is used within the space being heated. Multiple units can be purchased to put in various rooms in a home creating zones. One zone can be set warmer than another. As these units are utilized the household furnace thermostat can be lowered saving natural gas costs.

For instance, units can be placed in a living room, den, and some bedrooms. During the day the units in the bedrooms can be lowered to a lower heat setting while the living room and den units can be raised a bit higher. When you come home you can set the living room and den units higher throughout the evening. Prior to going to bed you can lower them and turn up the bedroom units. All the while the furnace thermostat can be lowered to reduce natural gas costs.

The electric cost to run an iHeater or EdenPURE unit is about 10-12 cents per 1,000 watts per hour. So a 1,000 watt EdenPURE unit would cost about 10 cents an hour while operating and the iHeater 1500 running at 1,500 watts would cost about 15 cents an hour when operating. Since these units are equipped with thermostats they cycle themselves off when the ambient air reaches your desired heat setting. Generally, when using these units they would be turned on, set to your desired temperature setting, and left on to cycle on and off to maintain the room temperature at your setting.

Replacement Panels, Lots of Orders, and other stuff!

Hi everyone,

I want to thank all of my customers for their loyalty to my virtual store of electric radiant infrared heating products. It is a niche business and in this economy I am amazed at how many loyal followers of this great heat are buying units and replacement panels as winter approaches.

I have had many, many orders since the beginning of the Fall season for replacement panels for electric radiant infrared heaters. There are many such units across the country that are made by a variety of manufacturers that are no longer in business whose flat panels were made of glass.  Many of you who are replacing those glass panels are reporting that they lasted you anywhere from 15-25 years.  Amazing!!  

The replacement panels are NOT glass.  They are flat ceramic over steel panels that are thinner than the original glass.  They come shipped to you with silicon spacers for a good fit in the original housing.
When ordering it is very important to remember to measure your original glass panel to get an exact length and width of the panel onlyDo Not add the housing into that measurement.  If you don't have the panel available then measure the inside of the housing where the panel would fit.  Now that measurement may not be as exact as measuring the original glass panel, so before ordering, here is what you do... get a piece of thin luan wood, or a piece of thin dry wall, or a thick piece of card board and cut out the measurement you took then try to get that to fit in the housing as if it were the panel.  This will be a good gauge to confirm you have the right measurements for the panel you need.

Our replacement panels come in whole inches, there are no 1/2 or 1/4 or 1/8ths of inches.  You can find the various panels in beige or white and in 4 different voltages at  Our panels replace the following manufacturers: API, Glassheat, Berko, Infrared Circuits, Continental Radiant, Lincoln Electric, Electroglass, and Zell-Aire units.  Our panels are available in the following sizes (L x W) in inches:  5x27, 5x45, 6x32, 6x45, 9x24, 9x32, 9x45, 9x48, 10x16, 14x21, 14x31, 14x45, 15x20, and 16x24.  If you do not have one of these sizes please contact us about a custom size being manufactured for your specific need.  Feel free to contact me anytime at our contact page at regarding the replacement panels.

Besides lots of orders I have been out to a large warehouse west of Cleveland to build a job where the owner wants to heat a large area of the warehouse where the workers perform most of the business fulfillment tasks.  That was a fun project.  I also had a restaurant inquire about outdoor electric infrared radiant heating of a patio where diners can be warmed while eating or being bar side during cooler times late in the season, or even in the early spring.  Customers enjoy the outdoors and the restaurant can extend its outdoor season with electric infrared radiant heat.  It is good to be able to flip outdoor dining tables on a crowded night and earn revenue from an outdoor space that otherwise would be dead to restaurant revenue generation.  It is a good marketing tool as well.

And your customers who smoke can have a warm designated smoking area.  hey, you want to keep those customers who smoke, so warm them.  They spend they same money at your establishment as non-smokers, so don't send them into the cold for that smoke.  In the cooler and winter months install some plastic or canvass side walls against your business exterior and add electric radiant heat for the smokers.

Thanks for the support and the orders!  stay warm everyone and please pass the word on infrared radiant heating.  It is good for you and for the ecology, stay warm, stay green!

Understanding Wattage and Voltages of Electric Infrared Radiant Heaters

The question has been asked of me if a higher voltage unit uses less power.  Specifically, if the CeramiCercuit Flat panel electric radiant heater model 945C would use less power if configured at 240 volts than at 120 volts.

First, wattage…. The 945C uses 1000 watts and the 1445C uses 1500 watts.  The level of power is the same in wattage regardless of the voltage.  If 1000 watts comes through a 120 volt circuit (the wiring in your home or office) it is the same as if the 1000 watts were coming through a 240 circuit.  Watts is watts.

Now voltage…. The load coming in through the circuit is measured in amps.  The circuit is configured or wired by voltage.
If the circuit is wired for 120 volts the amp load is 8.3 for the 1000 watt unit and 12.5 for the 1500 watt unit.
If the circuit is 240 volts the amp load is 4.16 for the 1000 watt unit and 6.25 for the 1500 watt unit. 

As you can see, when the voltage in the wiring of the circuit goes up the amps drawn by the unit comes down. 
Let’s say the voltage of the circuit was 480 volts….the 1000 watt unit would draw 2 amps and the 1500 watt unit would draw 3.1 amps. 

A higher voltage circuit can accommodate more amp load.  That load is limited by the total amp load of the circuit.  That is what a circuit breaker does (or a fuse).  If the load goes over the max, the circuit breaks flips off or the fuse blows and needs replaced.  If the circuits maximum load is 30 amps, then the most you could put on the circuit is about 27 amps… always want a little less than the circuit can handle. 

To calculate total load of all of your units on any one circuit you figure out the wattage of the unit and the voltage of the circuit to get amps and then multiply the number of units by those amps.  Example, on a 120 voltage circuit a 945C unit pulling 1000 watts draws 8.3 amps.   Three of those units on that same circuit will draw 24.9 amps (3 units x 8.3 amps).  If the circuits max load is 30 amps, you’d stop with three units because one more unit will go over the 30 amp max load for the circuit.

Another example….  a 945C unit on a 240 volts circuit draws 4.16 amps.  If the 240 circuit has a 30 amp max load then 6, maybe 7, units can go on that circuit.  If the same circuit is 120 volts then only 3 of the 945C units could go on it.  In this example the max load of the circuit is the same, 30 amps.  The reason more units can go on a 240 volt circuit is because 240 volts lowers the amps drawn by the unit allowing more units to be on that circuit.  The units wattages remains the same, but the amps drawn by that wattage decrease as the voltage of the circuit increases.  So if the voltage of the circuit was 480 volts the amps drawn would really drop allowing for even more units to go on that circuit before maxing out the max load of 30 amps.

The higher the voltage of the circuit the lower the amp draw.  As the amp draw lowers more load can be put on a circuit.  There isn’t so much an efficiency of power with higher voltage as much as there is efficiency in the circuit.  With higher voltage more load can be on the circuit.

We Do Warehouses

I spent the afternoon yesterday at a warehouse in Strongsville, Ohio.  It is a very large facility that houses a large volume of products for shipping fulfillment services.  It is heated with natural gas which is expensive.  They want to keep their employees warmer in winter, but they want to reduce the cost of natural gas use.

The temperature in winter months within the warehouse, even with the natural gas flowing into the current heating system, hovers at about 50 degrees F.  And that is using natural gas to heat the whole warehouse.  None of the products stored for fulfillment services need to be warmed, they can sit on shelves in the warehouse awaiting shipment in any temperature.  However, the workers certainly need to be heated and plumbing can not be allowed to freeze.  So what is the answer? 

The answer is infrared radiant heating. 

The workers spend most of their time in an area that is about 120 x 30 sq ft.  This is the primary area where fulfilled shipments are packaged and shipped.  By heating that area with infrared radiant heating the workers can be kept warm and have the ability in raise or lower the intensity of the radiant heat.  At the same time the use of natural gas heating can be reduced throughout the rest of the warehouse.  The natural gas system can be run at a rate such that none of the plumbing freezes, but its use, consumption, and cost is reduced.  Further, this warehouse is using my services to analyze their utility cost overhead and reduce the utility rates to lower rates from an alternative supplier.  Ohio is a deregulated state in the utility industry so competition has flourished and this warehouse can enjoy lower gas and electric rates.

This warehouse will benefit from a blend of heating solutions.  They will use natural gas at a reduced rate to heat the whole warehouse to take the chill off and keep pipes from freezing, use effective and efficient electric infrared radiant heat to heat workers, and have a lower electric rate which offsets the cost of electric heating.  Further lowering the electric cost is that at the end of the workday the electric units are shut off.  During the day, because they are installed in zones, workers can have some zones on, some off, and control intensity all of which controls cost.  There is no cost when they are no in use.

Time to Think Heat

It is that time of year again when weather cools after Labor Day, Football season begins, and the kids are back in school.

With cooling weather it is time to think of heat.  Here are some considerations:
  • That drafty room you've been wanting to heat.
  • Heating your three season room.
  • Heating you garage, shed, workspace.
  • Foot heaters in the office.
  • Heating the foyer or patio of a restaurant.
  • Heating a designated smoking area for employees.
  • Heating your craft or work room.
  • Adding heat to your Gazebo or outdoor entertaining area.
This list can extend on and on.  You get the idea, you can add heat to any room in your home for extra comfort heating, to lower you gas bill, to warm a child or older person living with you, or for any other reason.

Infrared Radiant heating is a superior comfort heating generating the warmth of the sun without noise, moving parts, blowing air, and it does so economically at about 10-12 cents per 1000 watts per hour.

Please give me a call or an email now so you can feel the warmth this winter season.

Contractors & Home Refurbishing - Remodeling

March 1, 2011
Kevin Owens

A perfect solution to adding heat to a home during a construction or addition project is using radiant ceramic flat panel electric infrared heaters.  They are cost effective, efficient, eco-friendly, and a primary heat source of comfortable absorbing heat.  They even warm the floor! This solution is applicable whether building an addition on a home, adding a three season glass enclosure or patio enclosure, remodeling a home, or refurbishing an older home.  These units are the perfect solution for homes that have that one room that never stays warm enough.

So the question is how does this apply to the construction and refurbishing industry of older homes, home with additions being built, or green home construction?  Using electric radiant infrared flat ceramic panels offers a dual benefit.  The first is to bring heat to additions being built without running new tin and without the worry of the current furnace being powerful enough to handle the additional square footage.  The second is to add a more effective and efficient primary heat source to the home or addition. Particularly a heat source that utilizes green technology that operates at a savings of up to 50% over the cost to heat the same space with natural gas.

Heating electrically has historically been less expensive than heating with natural gas or oil.  That is because using 1000 watts of electricity costs about 10-12 cents per hour to run.  But more than that heating with electric infrared technology reduces the recovery time of heating a room.  This means the heating unit does not have to operate as frequently to keep the room warm or to re-heat the room after a door or window was opened.

A quick explanation and review of the efficiency and cost savings of infrared radiant heating follows in the next two paragraphs, then I will explain the benefit of ceramic flat panel infrared radiant heaters in the construction and refurbishing industry of older homes, home with additions being built, adding heat to patio enclosures or green home construction.

The reason why electric radiant infrared flat panel heaters are efficient and cost effective to operate can be explained this way; forced heated air systems only blow warm air into the room.  The room must be filled with enough warm air to make a person feel warm.  But at that point the only thing that is warm is the air, but hot air rises.  There is usually a difference in temperature between the air at the ceiling and the air at the floor.  The space at floor level and a few inches above the floor is never comfortably warm and is usually drafty.  To fill a room with heated air takes time and, the air is warmed before the person is warmed.   The room cools rapidly due to cold air infiltration, and takes longer to recover.  But the biggest disadvantage is that the forced air system must run longer and work hard to heat the air in the room and then reheat the room which costs the consumer more energy dollars.

Conversely, infrared radiant heating heats people and objects first by utilizing the technology of long wave electromagnetic energy.  After the people and objects are warmed they release the warmth into the air which then heats the ambient air.  Even if a door is opened that lets a rush of cold air into the room, radiant heating has a faster recovery time due to all the objects in the room being warmed and releasing that warmth back into the room.  Even though the unit operates continuously until the thermostat turns it off, it operates at an inexpensive rate.  And that cost is only incurred when the unit is running whereas a gas system is always burning a pilot light and trying to overcome drafty cold air infiltration. 

The electric radiant infrared flat ceramic panels are manufactured by Radiant Electric Heat (REH) in Wisconsin.   These units are made in the USA.  That is important to a lot of consumers and I am happy to point that out.  The REH brand is called CeramiCircuit ™. 

The CeramiCircuit ™ brand is constructed of ceramic coated 18 gauge steel plates with an energizing   circuit on the internal face of the heating element.  The heater body is a 20 gauge galvanized steel                                               construct with ventilation slots at perimeter.  The unit is made with a junction box of approximately 135 cubic inches running the width of the heater on the back side of the heater body.  Three 7/8” standard knockouts located left, right, and center, are built onto the rear surface of the junction box to allow entry of power feed. Actual power connections to the element and heater grounding connection are located at the left end of the heater. The heater elements have a wattage density of approximately 2.5 – 3.0 watts/square inch of emissive surface area.   The popular residential ceiling cove units are rated at 825 watts (Model 645) or 1000 watts (Model 945) in appropriate voltages of 120 volts, 208 volts, 240 volts, or 277 volts.  REH also makes CeramiCircuit ™ brand units in the following configurations: wall mounts, baseboards, large portable units (on casters or wall mount), and small under desk space heaters.  More information can be found at  The products at this page each have a link to the product brochure for more information.   Some of the above detail of the unit construction came from those brochures.

            During new and/or green construction, the building of an addition, any type of patio enclosure or three season room, or just a drafty, chilly room, the CeramiCircuit ™ brand of flat ceramic electric radiant infrared heating units offer perfect, efficient primary heat. They mount on two brackets that install like hanging a picture frame, they come with lead wire for behind the wall wiring offering a clean finished look, and the units can be zoned or operate on individual thermostats. 

            Instead of replacing or using a weak furnace or running extra duct work consider flat panel heating technology; the warmth of the sun in a box.  No emission, no forced air, no combustion, hypoallergenic, no maintenance, solid and durable, American made, and less expensive operating costs than other heating systems, the CeramiCircuit ™  line is tailor made for residential use.

Fifty % Saving on heating costs!

WOW ... 50% Savings!!   But how?

Simple, really.  Electric radiant infrared heat is so efficient that it offers greater warmth and comfort and costs less to operate than forced air natural gas furnace or blower systems.
It works this way:
Electric radiant infrared heat is a type of heat that is immediate and is absorbed by people and objects.  Even in a cold room when radiant heat is first turned on, human skin will feel the warmth and absorb the heat first which warms the person.  Within minutes theelectric radiant infrared heat is rapidly warming the objects in the room, like sunshine pouring in through a window.  As the radiant heat warms the room every object in the room, including the floor, is absorbing the heat.  These objects in turn release the heat into the room ultimately warming the ambient air in the room.  As the ambient air is warmed to the temperature set on the unit’s thermostat it will turn off.  While the unit is off the objects in the room continue to warm the room.  If a door or window is opened allowing cold air to rush into the room heating recovery is rapid due to the room warming from the objects in the room.
Any room being heated by an electric radiant infrared unit can have its damper to the furnace closed and be cut off from forced air heat.  The room can be heated for half the cost that it took to heat with forced heated air.
Here's why:
As the unit is operating and warming the room the consumer cost is about 8-12 cents per kilowatt hour to operate (an approximate average of 10 cents an hour per 1000 watts - refer to your rates per kilowatt hour on your electric bill).  When the room is not in use the unit thermostat can be lowered or turned off.  So, a 3000 watt unit would cost about 30 cents an hour to operate when it is turned on.  It costs nothing when turned off.  Therefore, with immediate heating, faster recovery times, and inexpensive electric costs on a decentralized heating unit, the savings to heat any equivalent square footage of space compared to natural gas or heating oil is about 50%.  
Natural gas systems continuously run a pilot light and a natural gas burner to blow heated air into the rooms of a home or building to warm the people in the room.  But, these systems only heat the air.  We know that hot air rises up to ceilings leaving a colder temperature at floor level (thus the use of space heaters and foot warmers).  This happens day and night whether or not anyone is using the room.  When a door or window is opened and the cold air rushes in the furnace activates by turning on the natural gas burner to force more hot air into the room and doesn't shut off until the thermostat indicates enough hot air has filled the room.  That is a lot of hot air because as hot air rises enough hot air must be blown into the room to reach the thermostat.  Also, in a cold room, a person will feel cold until sufficient hot air is in the room to make the person feel warm.  The person is warmed last.  Because the furnace is a centralized system it does this continuously for the whole house even if one room is being used.  At current gas prices, this can get expensive.   If you are paying a lot for natural gas or heating oil you've already paid for electric radiant infrared heatingunits, you just don't have them.
To mitigate such gas or heating oil costs and to have very comfortable and efficient heating a consumer can install electric radiant infrared heat in one or more of the most commonly used rooms.  Over time additional rooms can have electric radiant infrared heatinstalled.  Or, a consumer can invest in a home improvement project to convert the whole home from natural gas to electric radiant infrared heating.
Either way the savings remain about 50% of the cost of natural gas to heat the same space with electric radiant infrared heatingunits.  These savings come from immediate heating, faster recovery times, and inexpensive electric costs on a decentralized heating unit.  The savings grow over time as the cost of the units and their install is quickly recovered over a short number of years while the units last the lifetime of your home.  And it is very comfortable.  And….its green!

Easy Installation of Our Units

Radiant Heat USA sells infrared radiant heaters that are manufactured in a variety of electrical configurations based on the needs of our customers.  These configurations are listed as volts for each item in our store.  Typical voltages are 120, 208, 240, 277, 480, 600.  Units with higher heating power are manufactured at higher voltages.  Most outlets in residential homes are configured to accept appliances rated at 120 volts.
Radiant Heat USA sells many heaters that require little or no electrical installation.  These units are 120 volts and can be plugged into a standard residential outlet.  If a customer has preferences about hiding the power cord within a wall, moving an outlet, or -more commonly- installing a thermostat, some electrical work is required.
Each heating unit has an amp rating that is related to its voltage.  The higher the  heating unit's voltage the lower the amp draw through the electical circuit that the heating unit is plugged into.  If lower amps are desired then higher voltage heater units must be ordered.
For example: The Ceiling Cove Model 945 with 120 volts puts out 1000 watts of power at 8.3 amps is hardwired to a 110 volt residential outlet.  A customer may want a timer or a thermostat to control the heater which requires light electrical work.  That same heater with the same wattage is also manufactured in a 240 volt unit which draws only 4.2 amps, about half the amp draw of the 120 volt model.
Some commercial or other buildings require a unit configured to 208 or 277 volts which draw 4.8 or 3.6 amps respectiviely.  So again, the higher the voltage of the unit, the lower the amp draw through the electrical circuit that it is plugged or wired into.
When a home or building does not have the proper wiring to handle the voltage or amp load an electrician is required to properly wire the location to accept the heater unit.  For instance, if a heating unit that requires 240 volts is being installed in an area where there is only a 120 volt outlet, an electrician must run the proper wiring to accomodate the 240 volt unit.  Cost for this varies among independent electricians and estimates should be sought prior to installations.
Radiant Heat USA does not perform installations.  We do, however, recommend electricians and suggest sources for customers to locate a reputable certified electrician when it is necessary to utilize such service.

Electric Radiant Infrared Glass Heating Elements

Electric Radiant Infrared Glass Heating Elements

Good day my faithful customers… I hear there is a demand for replacement panels!  I am here to help.
Many of you are seeking glass element replacement panels for your electric infrared radiant heating units.  I know the search is on as several of you have contacted me seeking replacements.  Most of you have a glass element in the heating unit from these manufacturers: API, Glassheat, Berko, Infra Red Circuits, Continental Radiant, Lincoln Electric, Electroglass, and Zell-aire. These units had textured glass panel elements with the circuit sprayed painted on the back.
You came to the right place.  I can replace most of these elements.  These units had glass elements.  They now get replaced with a ceramic heater element that is constructed of  ceramic coated 18 gauge steel plate with an energizing circuit on the internal face of the heating element (the backside of the panel).  Heater elements have a wattage density of a minimum of 2.3 watts/square inch of emissive surface area.  Enough technical talk.  We have replacement panels!
The glass elements were thicker than the ceramic replacements.  To accommodate the size difference the ceramic elements come with silicone spacers.  The elements are easy to install.  To order please advise me of the length and the width of the origianl element.  I do not need the length and width of its housing, just the length and width of the original glass element.  I say that twice because I get calls where that is forgotten.  I want to make the ordering as fast and easy as possible.  With that I can be sure to get the right size if available.  Also indicate the voltage of your unit and if you prefer beige or white ceramic.  I can’t complete an order without the voltage of the unit.
As always your comments are welcome.
Thanks, and enjoy!
