How to Install Undercounter Heating Mats

Lifestyle of a Kitchen with Electric Radiant Countertop Heaters

If you are one of the many owners of granite, quartz, soapstone slabs, natural stone, marble, or concrete counters, then you have most likely noticed how cold the surface feels to lean on. With winter right around the corner, the thought of sitting at a cold kitchen countertop everyday can be off putting.

To solve this problem, many homeowners decide to add an extra element to their kitchen design: heat under their kitchen island or countertop seating area, specifically the place where you most often rest your arms. We’re not talking about extreme heat with the finished product; just a little bit of warmth to take away that initial “shock” when your bare skin touches the stone.

So, how can this be done and how much work does this project take? What about the fixed costs? For both new and existing countertops, adding warmth with FeelsWarm® countertop heaters is a surprisingly simple process, one that does not typically require hiring an electrician or contractor.

Installing Undercounter Heat

Installing a countertop heater is extremely easy, just follow the steps below.

1.     Purchase a WarmlyYours FeelsWarm® stick-on heating mat, one that can be customized to fit the exact size and shape of your overhang. It is recommended to only heat the area where you commonly sit. 

2.     Apply a light layer of two-part epoxy to the underside of your countertop. (Epoxy is included with all countertop heating mats). This step is typically required for "rough cut" natural stone countertops such as quartz or granite countertop materials. Smooth granite and any stone with a mesh backing will most likely not need this thin layer of epoxy. 

3.     Using a simple “peel-and-stick” method, remove the release liner from the mat and apply the adhesive side underneath your countertop, approximately ½” away from the outer edges.

4.     After locating an outlet inside of your cabinet, drill a small hole into your cupboard under the overhang area and feed the heater cord through the hole. 

5.     Included with all countertop heating mats is a low-voltage transformer, which plugs directly into a standard outlet and can be bolted up on the wall in your cabinet. Simply plug the mat into its transformer and your heater will begin warming up. You can also utilize a thermostat controller which allows you to dial the temperature of the heating mat down if desired.

Here's a short video outlining the entire process.

Cost to Operate Countertop Heaters

Once you have plugged in your heating mat, you can run it 24/7 without a temperature control as it costs practically nothing to utilize. The cost to operate a countertop heater for 24 hours is approximately 10 cents. This can, of course, vary to a small degree based on local electrical costs and the square foot coverage of the mats. Regardless, it's a very small price to pay for comfort.
