How do I work with my electrician to install WarmlyYours electric floor heating?

While WarmlyYours electric radiant floor heating systems are typically installed by your floor covering contractor, a licensed electrician is recommended for the final thermostat hook-up. With every quote, we provide an Installation Plan layout, together with an electrical plan that has all the info required for the electrician.

Is electric floor heating safe and what about EMF?

Our electric radiant floor heating systems have withstood rigorous safety testing and earned the UL listing. They produce much less EMF than common household appliances like your TV or vacuum cleaner. The EPRI (Electric Power Research Institute) tests all electrical devices and publishes the data. Many common household appliances are tested at a distance of 6 inches. The test results indicate that on average, the EMF emitted for the following appliances, measured in Milligauss (mG) units, is:

Vacuum Cleaner: 300 mG

Microwave: 200 mG

Portable Heater: 100 mG

Dishwasher: 20 mG

Washing Machine: 20 mG

WarmlyYours TempZone™ (Twin): 1.8 mG

What type of flooring can I install along with an electric floor heating system?

WarmlyYours’ TempZone™ product is most commonly installed under tile, stone, and marble flooring, but can also be installed under many other popular floor covering options such as hardwood, vinyl and linoleum. We also have our Environ system, which is an electric floor heating product as well and is specially designed for installation under carpet (in the U.S. only), laminate and floating wood. WarmlyYours can accommodate any flooring type with either of the electric radiant floor heating products that we offer. If your flooring type isn't listed here, just give us a call at (800) 875-5285 and we will be happy to discuss it with you.

What voltage does WarmlyYours floor heating systems utilize?

The floor heating systems are offered in both 120 volt and 240 volt for the North American market. A 208 volt breaker panel can also accommodate our 240 volt floor heating system. It is important to note that the energy consumption will be the same: a 240 volt system will not cost more to operate than a 120 volt system. You are billed in kilowatts, and the 120 volt and 240 volt systems use the same amount of kilowatts. WarmlyYours often specifies a 120 volt system in smaller projects while a 240 volt system is typically recommended for larger projects (120 square feet of electric floor heating coverage or more). The benefit of switching to a 240 volt system is the reduction in amperage. Our programmable thermostat can control a radiant floor system up to 15 amps. The 120 volt system will reach 15 amps at 120 square feet of electric floor heating coverage. However, the 240 volt system will reach 15 amps at 240 square feet of electric floor heating coverage, allowing a much larger system to be connected to the thermostat. For installations over 240 square feet, a relay contactor or power modules are needed.

I called to get information and spoke to Jennifer. After reviewing all the information on your company I sent a drawing , with the help of your on line tools , planners and Jennifer all the components were shipped by the end of the next day.. All went as planned. And promised. Jennifer really knows your product and is an asset to your organization. It’s refreshing to know that companies such as yours still exist. We had delays in construction , the system has been installed now for a few weeks, for well and we are ver pleased with the performance.

We have received prompt service and and excellent buys. This particular order has not been installed, but we have bought from you many times and received shipments promptly, and the products were as described and worked well.

Daniels first home

Kory N., Portland, OR on 04/09/2023

When buying you first home, cost is always a concern. Daniel was worried about the added cost of a heated floor because it seemed the realm of the wealthy. After explaining of how economical the equipment really is compared to the impact on resale value he was convinced to give it a try. He absolutely loves his floor and talks about it constantly. He now claims he will never do a bathroom floor without it.

Cozy Toes!

Anonymous, Albuquerque, NM on 03/06/2023

I enjoy heated floors so much. This is perfect in my small bathroom. Makes for warm feet in the middle of the night, early morning.
