Electric underfloor heating is a modern and efficient way of heating your home and it uses cables or mats to generate radiant heat that rises from the floor.

However, before opting for the first kit you see, it’s important that you take accurate measurements beforehand. This is because many of the mats included within the kits can’t be cut and this can make the installation more challenging.

Just as important as the size is whether or not the kit is compatible with your flooring because some may be suitable for tiles whereas others are designed for laminate.

From our experience, electric underfloor heating can be easily installed by most keen DIY’ers and it’s a great way to increase the warmth in a cold room.

To help you choose the right electric underfloor heating for your home, our hand-picked selection features top-performing kits chosen through our first-hand experience installing them under tiles, laminate and carpet, testing and the latest research.

How The DIY Works Team Tests & Rates Electric Underfloor Heating Kits

When compared to warm water systems, electric underfloor heating is much simpler to install and many kits can be installed yourself relatively easily.

We have experience installing multiple systems that involve underneath tiles to laminate and it’s certainly a task any keen DIY’er can accomplish.

All of our recommendations come as complete kits and are ready to install out of the box. During our ongoing testing of the kits, we analyse their build quality, ease of installation and operation, thermostat and heating performance.

As you can see in the images below, we recently installed electric underfloor heating in an extension of a house we were renovating to act as a primary heat source.

After laying down the mats, we tested that they were working using a multimeter (we highly recommend doing this) before laying the screed.

Once the screed had dried, we then continued to tile the floor. For this particular installation, we opted for a WiFi-enabled smart thermostat to control the heating as we personally find them much easier to set up and control.

5. Best Budget: HEATIT Electric Underfloor Heating

(How We Review →)

Another budget-friendly electric underfloor heating kit is by the HEATIT brand and it’s another option that’s versatile as it can be used underneath most types of flooring.

To conclude, the HEATIT kit is an excellent all-round option for electrically heating the floor anywhere in your home. It’s also been designed to make the DIY installation go as smoothly as possible, which is great for those that have never laid underfloor heating before.

Conclusion

Whether you want to install electric underfloor heating as a primary or secondary heat source, there is a wide range of kits available that can all be installed yourself. As shown above, we’ve installed multiple ourselves and as long as you are a keen DIY’er, it’s a job that shouldn’t be too difficult to accomplish.

All of our recommendations include heating cables that are fluoropolymer coated and available in a variety of sizes. However, in terms of the thermostat, we always recommend opting for smart WiFi-enabled options if your budget allows because most “standard” thermostats can be difficult to set up and use and you’ll more than likely want to upgrade it.
