A Guide to Underfloor Heating

A Guide to Underfloor Heating

Underfloor heating is the way forward.

We’re sure you’ve noticed it: more and more self-build homes are choosing this method of heating. Why? It’s cost effective and one of the most energy efficient options for heating homes. Underfloor heating allows a gentle radiation of heat throughout the home, similar to what the natural heat of the sun is able to provide.

The huge benefit of underfloor heating is that your whole room will be heated - you won’t find yourself getting cooler the further away you are from the radiator. Customers also like the discreetness of this option; the home is heated without any visible radiators or pipes, leaving completely unhindered their room layout.

However, other benefits that you’ll often find that customers don’t consider is the reduction in energy costs due to this system working better on lower temperatures especially when installed with an air-to-water heat pump. Underfloor heating can also have health benefits, dust and pollen movement that gets circulated by convection from radiators will be greatly reduced making this a must-have recommendation for those with chest or breathing problems.

There are two types of underfloor heating systems you can install in your customers homes:


A network of pipes connecting to the house boiler, this option will pump hot water through the pipes to all the rooms and creates a gentle warmth. This is the cheaper option to provide to your customers however you’ll find there is quite a bit of work involved in this option as the pipes need to be buried in a screed floor with 3 inches on top to create a thermal mass.


This network of wires heats up the floor using electric coils under the floor to achieve warmth. You’ll find when pricing that this option is cheaper than wet installations, however this option works best for use in just one room. This underfloor heating can work under many types of flooring but should never be installed under carpets.


When laying your underfloor heating you will want to consider how materials expand and contract over time and how this will affect your project. The screed that is laid with your piping will expand and contract, along with any tiling that is fitted on top. Take this into account and make sure an expansion gap is left when installing over large areas. Take into account your customers requirements along with the practical requirements such as floor depth.

All new builds must have insulation positioned below the concrete slabs. Underfloor heating should also have insulation above the slab and directly below the pipes to reduce the effects of downward heat loss.

This fantastic form of heating is no longer just for up market establishments, bring this luxury to your customers homes. Contact PLUMBMASTER today to see how we can help you with underfloor heating.
