Doing anything for the first time can seem daunting, especially if it is a DIY project, so we understand why people can find the prospect of installing their own underfloor heating system unnerving. However, if you have the right tools and have spent sufficient time preparing you will find that it is a surprisingly simple process. You will receive an installation guide regardless of whether you order an electric underfloor heating system or a warm water underfloor heating system, but here is a quick guide so you can get an idea of what to expect.

Preparation

As with everything, proper preparation is essential to a successful and easy underfloor heating installation. You will need to take into consideration how easy it will be to access the floors in your home and more importantly how easy will it be to install the underfloor system, will it be installed between the joists in your floor, or will it be installed on a solid floor underneath tiles? It is also taking into consideration which type of floor covering you wish to use, ceramic, tile and stone floor benefit greatly from underfloor heating whereas certain high tog carpets struggle to let the heat pass through effectively.

Installing an Electric Underfloor Heating System

For safety reasons, when installing an electric underfloor heating system it is important to ensure that a qualified electrician sets things up for you.

One of the first things you need to do when installing an electric underfloor heating system is to fix insulation boards to the sub-flooring. This is essential because these insulation boards ensure that the heat is sent upwards into the room and does not escape downwards into the flooring. If you are installing your electric underfloor heating mats on a concrete floor these insulation boards can be fixed using adhesive, whereas if you were to install them on a timber floor these will be able to be drilled with ease.

After the insulation boards are in place you are finally ready to lay some underfloor heating. For a nice simple square room with very few awkward corners, you can simply measure, cut and lay a mesh system, however, if you are wanting to lay your system in a more complex shaped room you may find it easier to use a ‘loose wire system’. This type of system is more flexible and allows you to install underfloor heating in even the most obscure shaped rooms.

It is important when laying your electric heating system to make sure that the power supply can be fitted to your homes electric supply easily, this may seem obvious but it is also a common mistake!

 

Installing a Warm-Water or ‘wet’ Heating System

Installing a ‘wet’ or water-based underfloor heating can be just as simple as a dry system, the biggest difference is that a water-based underfloor system does not need to be tied into your electric supply.

Just like with an electric underfloor heating system preparation is also key, the sub-flooring needs to be clean and clear of debris so the insulation board can be fitted properly. Again these insulation boards are key to reducing heat loss and promoting heat efficiency.

A clean and clear installation guide is provided with all of our DIY underfloor heating packs, this will provide you with all the information you need to get your pipework laid out in the most efficient manner. Before all of this, it is important to install the main heating manifold, this needs to be located close to the room, or rooms that your system will be heating. The manifold helps you to monitor the temperature of the water flowing through your system

After you have laid the pipe and fixed it securely to the insulation it is time to run a water pressure test and start to apply the screed. It is important to ensure that the manifold is plumbed directly from your boiled and before any radiators, this ensures that your manifold gets a direct flow of warm water from your boiler. Due to the complexity of this part of the installation, it is advisable to consult a qualified plumber at this point.
