Creating a comfortable home is so much more than just the flow of the design and layout. It’s more than the interior decorating, and even your color choice. In order to feel comfortable in your home, you need to keep your home at the right temperature.

The studies show that radiant floor heat is all around the most comfortable type of heat out there. We’re going to walk you through how easy it is to install Goldheat’s product!

Here’s the thing. With Gold Heat Radiant Floor heat, you literally get all of the benefits of walking on coal, with NONE of the negatives! You get bragging rights, and you get the warmth without burning your feet. Now that’s a deal if you ask me.

Installing Electric Radiant Floor Heat

First things first. Gold Heat literally creates a custom radiant floor heat mat that is designed to fit your specific floor plan. Yes, that’s right! You need to send in your floor plan design with the specs and they will create the radiant floor heat mat, and ship you the mat.

You need to prep the space. Make sure it’s smooth. No nails sticking up, and that you’ve filled any major cracks in the subfloor.

Next, you will roll out the custom mat that Gold heat sent you. You’ll want to staple it down to the floor. (make sure you don’t hit the wires!)

Then you’ll want to hook the wires up to the thermostat. (it’s cleanest if you can run the wires connecting to the thermostat through the wall.)

Once you’ve done this, you’ll want to make sure you mount the in-floor sensor! In floor sensors are very important. You want to make sure that it’s mounted in the right spot, so refer to the instruction manual for locating it.

Oh, and I wanted to mention, most flooring companies will void their warranty if you had radiant floor heat with no in floor sensors. So, you’ll want to make sure you don’t miss this step!

After you’ve gotten the floor sensor in place, you’ll want a thin layer of flexible mortar to cover the radiant floor heat mat. This will do two things:

  1. It will make sure you protect your radiant floor heat mat. With the electrical components right there, you’ll want to make sure
  2. Allow the Radiant Floor Heat to work it’s magic! The concrete actually absorbs the heat, and releases it in a very smooth way that creates the comfort you’re looking for.

I know, I know. A lot of people talk about how they don’t want to cover the floor with mortar because it’s too heavy.

However, this is actually a misconception.

You’ll likely need only a bag or two of mortar, which will be likely less than 80 lbs total.

Flooring in a tiny home on the low end weighs 150 lbs, so it’s basically less than half of what your flooring itself will weigh.

Once the mortar has cured, you’ll be able to install your flooring just like normal. If you’re tiling, no need to add a layer of cement board underneath it.

You’ll want to bring your floor sensor and hook it up to your thermostat as well.

Radiant Floor Heat

Hopefully you’ve considered radiant floor heat as a comfortable and sustainable way to heat your tiny home or cabin, and make sure you check out Gold Heat. The premium and industry leading electric floor heat in the mobile living industry. Especially great for small spaces.

In the words of Gold Heat’s engineer Jim P., “Keeping toes warm out there on the frontiers of freedom.”

Radiant Floor Heat Keeps Your Toes Warm

Oh, and here’s a pro tip! The most common reason for electric floor heating to fail is because of dog beds! Because they are generally pretty thick, it keeps the heat in and fries the circuit! Make sure there isn't too much "insulation" like a really thick rug that will over heat and trip the safety features.
