Electric Underfloor Heating: How Does Electric Underfloor Heating Work?

Electric Underfloor Heating: How Does Electric Underfloor Heating Work?

Electric underfloor heating has continued it’s growing trend and I’m finding more and more customers are asking me to install underfloor heating systems in their homes. I get asked all the time how it actually works and how much it costs. I wanted to use this blog post to explain how electric under floor heating systems work. I’ll explain how water underfloor heating systems work in a separate blog post.

First of all, why is it so popular? According to research by, the total underfloor heating market is expected to reach USD 7.90 Billion by 2020. That’s right – nearly USD 8 Billion! There has been a huge shift in the mindset of the global economy with a big emphasis placed on sustainability and efficiency. This is where electric underfloor heating wins. If installed correctly it is far more energy efficient then traditional central heating systems.

So What’s The Main Difference Between Radiators And Electric Underfloor Heating?

Radiators only heat the cold air in their immediate vicinity using convection. This hot air rises and then cools down. This air then falls again and is heated up again and rises again, then cools down, then falls again etc.. It does the job but the heat is not distributed evenly around the room so you do get warm spots and cold spots. This is especially true if the wrong sized radiator hasn’t been installed as the BTU heat loss hasn’t been calculated properly.

With underfloor heating, the whole floor is covered with the electric heating wire system so the floor acts like one big huge radiator. The wire heats up when the system is on, heats the floor which then provides evenly distributed radiant heat.

You get different types of electric underfloor heating such as a mat or foil system or a loose wire system. You also get different sizes in terms of heat outputs and wattage so that you can ensure that your room will be heated properly. It is very important to calculate the heat loss in your room correctly otherwise there’s a big risk that the room won’t be heated properly. If you’re not sure how to do this then give us a call and we can help.

A quick tip when considering electric underfloor heating is to install insulation boards. This helps to increase the room heat up time and it makes sure that heat energy isn’t lost by heating up the sub floor!

Isn’t Electric Underfloor Heating Expensive?

Surprisingly it’s relatively affordable so it’s definitely worth considering. There are many factors which contribute to the cost such as running time, room size, heat output and system type. A programmable room stat also helps as you can set times for when it comes on and turns off. Some of the stats are so advanced now that they actually suggest smarter ways to heat your home so that you save money!

Who Makes The Best Electric Underfloor Heating Systems?

Because of the size of the industry, there are lots of different manufacturers who probably all are just as good as each other. The tried and tested company who we normally always recommend are Warmup. They’re a huge global brand and their support and after sales service is amazing.
