Underfloor Heating

At TUS we understand that underfloorheating (UFH) can seem complicated, particularly if this is the first time you have considered installing it. For that reason we try to make things simple and informative to help you make the right decision over which system or products are right for your project.

We hope the information below helps to explain what underfloor heating is and why it is fast becoming the number one choice for homeowners, installers and developers.

Underfloor heating is very flexible and simple to install. It can be easily added to an existing building, perhaps as part of a conservatory or kitchen extension, or it can be installed as the main heating system for a new build project either domestic or commercial.

It can be used alongside traditional radiators or as the sole heating system for a property using either a traditional boiler or any of the emerging renewable heat sources such as ground source and air source heat pumps.

A number of factors will influence the decision over which components are required for any given type of application. Some of these factors include the number of rooms to be heated, the size of the rooms and the floor construction of the property. 

To get the best out of your underfloor heating system it is important that you have the system properly specified by a professional or company that specialises in UFH design. If you do not already have these why not let us take care of this for you? We can provide a full system design and CAD pipe layout from your set of plans or drawings.


Quite simply underfloor heating is a system that uses pipes below the floor to circulate warm water producing a heat source capable of heating the air above it to any required temperature.

Why should I choose UFH instead of radiators?

There are many benefits to be gained from installing underfloor heating instead of radiators. As underfloor heating operates at temperatures of around 35oC-50oC versus a radiator system operating at 70oC-80oC the amount of energy is far less resulting in lower running costs. A correctly designed underfloor heating system system in a fully insulated property can save up to 40% on running costs. Other benefits including greater comfort due to the radiant nature of the heat and the freedom to layout and decorate rooms without the need to consider radiators consuming wall space.

Can I have UFH & radiators in the same property?

Absolutely. It is quite common to see underfloor heating installed on the ground floor with radiators installed on the first floor. However, with the reduction in cost in recent years and the many benefits of installing underfloor heating it is becoming increasingly popular to install it throughout where possible.

Where homeowners are extending an existing property it is possible to install underfloor heating alongside an existing heating system. For example the existing property may have radiators as the primary heat source. However, underfloor heating can be installed in the new extension and controlled separately using it's own thermostat so the two systems do not conflict with one another.

What types of floor covering can be used with underfloor heating?

Most typical floor coverings are suitable for use with underfloor heating. The best conductors of the heat from the underfloor heating are typically stone and ceramic tiles. Timber and laminate floor coverings are also very popular. It is also possible to use carpet with underfloor heating but it is recommended that the combined tog value for the carpet and underlay does not exceed 2.5. Anything above this may impact on the amount of heat that is emitted.

Is underfloor heating an efficient form of heating?

Yes! Underfloor heating systems use low temperature water rather than traditional heating systems, such as radiators, which use high temperature water. As a result there is less demand from the boiler meaning lower running costs. Typically you can expect to save around 25-30% when installing a well desgned underfloor heating system versus a radiator system.  

When paired with a renewable heating source, such as an air source or ground source heat pump, the savings can be further increased. Talk to us for more information about renewable heating options.
