Underfloor Heating for Concrete

Installing Underfloor Heating with Concrete Flooring 

Concrete floors are a great partner for underfloor heating as concrete is a conductor and spreads the heat very well. The thermal mass of concrete helps the material retain heat to ensure that each room, and your entire home, can stay warmer for longer. This is a huge advantage to have over a conventional radiator system and with that in mind, a polished concrete floor can work incredibly well with underfloor heating. Plus, it looks great too! 

Installing Underfloor Heating with Concrete Flooring 

When using concrete as a floor finish with the Wunda Rapid Response® boards, you will need to apply a thin layer (5-10mm on top of the pipes and panels) of approved levelling compound for the concrete to be poured onto. When you are installing a system with concrete as a floor finish it’s important to know that you let the concrete dry naturally, rather than try to force dry it.  

The approved compounds are:

• ‘Ultra Level it TWO’, when primed using ‘Ultra Prime it multi surface primer’.
• ‘Mapei Ultraplan Renovation Screed’ when primed with ‘Mapei Eco Prim Grip’

While the levelling compound or primer is not provided by Wunda, it can be sourced from local merchants or online.

Underfloor Heating Energy Efficiency

Radiator systems are the 20th century equivalent of a fireplace. They need your boiler or heat pump to supply  hot water temperatures (60-80 degrees) so that they can emit heat into the room.

Water based Underfloor heating works differently, it is like having a huge radiator spread out beneath your floor. Underfloor heating can cover the entire floor space allowing it to use much lower water temperatures (35-45 degrees) to transmit heat throughout the room, making it the go to energy efficient and sustainable system of choice.
