How do I calculate how much underfloor heating is needed in my home?

Grant’s Uflex underfloor heating system is an increasingly popular choice of heat emitter due to its unobtrusive design and high efficiency levels. When considering how to heat individual rooms within your new build home there are many reasons to choose underfloor heating, but how exactly do you calculate how much underfloor heating your home needs?

As part of our free-of-charge home heating design service, when underfloor heating is selected as a heat emitter within the property, the technical team develop plans specifically for the Uflex underfloor heating system in individual rooms based on flow rates and heat loss calculations for each room. This provides invaluable support to the contractors on the project as it saves time and gives reassurance that the heating system has been professionally sized and specified to suit the requirements of the property.

Our expert technical team analyse house plans and undertake indepth heat loss calculations to determine the heating requirements for each room of the property. All recommended heating technologies are then correctly size and specified, resulting in a bespoke, highly efficient, integrated heating solution, which best suits the needs of the home and its occupants.  


Why choose Grant Uflex Underfloor heating for your home

Modern and Minimalistic Look

The Uflex system offers versatility to support the overall design and architecture of the space whilst also creating comfort. Underfloor heating is the perfect heat emitter choice for those who prefer a modern and minimalistic look as it is an invisible heat source and heat will not be blocked off by furniture.


Health Benefits

In addition to bringing warmth and comfort to a home, the Grant Uflex also brings health benefits as installing underfloor heating results in increased hygiene levels due to reduced air circulation transferring dust particles throughout the home.


Versatile Heat Emitter

The Grant Uflex underfloor heating system is a versatile heat emitter that works effectively with a main heat source, such as the Grant Aerona³ R32 air to water heat pump, to deliver high efficiencies and maximise long term financial and carbon savings as both technologies operate at low temperatures and therefore use less energy.


Easily Installed and Optimal Control

The Grant Uflex underfloor heating system is easily installed and offers optimal control with individual zone heating and comfort. It is especially suited under tile and hardwood flooring in kitchens, bathrooms, and open plan areas and is embedded in the floor's construction during the build.


How is the Grant Uflex underfloor heating system installed?

Grant’s Uflex underfloor heating system is embedded within the floor construction. The Uflex pipework is positioned and clipped into place once the flooring’s insulation and membrane has been fitted, after which a floor screed is poured over the top and allowed to fully dry before heat is introduced. With a drying time of up to thirty days, the system can be fitted as part of the floor construction process, therefore causing no delays in construction.
