Cooling with underfloor heating, delicious!

Turning on the underfloor heating is probably not the first thing you think about in summer temperatures. Yet with underfloor heating, the temperature in the house can be lowered by a few degrees, to a very pleasant level. And with the summer of last year still fresh in the memory, that is probably a nice idea.
We regularly receive questions from our customers about this way of cooling. Is this possible if I have a wooden (parquet) floor? Yes! Which can.

Many people already know that a wooden floor goes well with underfloor heating. But what many people do not yet know is that floor cooling can also be combined with parquet.

What is floor cooling?

Floor cooling is a pipe system (often in combination with underfloor heating) in the floor construction that ensures that the concrete floor does not heat up or even cool slightly. This keeps the temperature in the house pleasant. The temperature of the water in the pipes does not have to be extremely cold. Usually a few degrees below room temperature is enough to bring the room to a desired temperature.

What should you take into account if you have floor cooling?

With floor cooling, especially with floor cooling under parquet, it is very important that the heat resistance, including the under layers, is lower than the maximum Rc value. If this is taken into account, the exchange of energy with the installation is minimized.

Another aspect that must be taken into account with floor cooling is the risk of condensation. It is very important to keep a close eye on whether condensation occurs during the floor cooling.

Another part to take into account is the temperature. With floor cooling, the temperatures must remain within a certain limit. If the temperatures remain within these limits, nothing is wrong. If the temperatures rise above this, there is a risk of damage such as cracks and cracks in the wooden floor. To prevent this, we therefore advise to keep a close eye on and protect the temperature of the floor cooling. The can is very easy by applying good condensation monitoring.

Do you want to make your current underfloor heating system suitable for underfloor cooling? Or do you want to install a new system that can heat and cool? We can help you find a specialist in your area.


Can any underfloor heating system cool?
Unfortunately, this is not the case. A standard underfloor heating is connected to the boiler. To cool, a liquid temperature is needed that is below the ambient temperature. This low temperature is not reached with a central heating boiler. For example, if it is 30-35 degrees Celsius in the house, the water in the central heating system is also warm. Pumping this around doesn’t solve anything.

What adjustment in the underfloor heating is necessary to cool?
With a ground-bound heat pump it is possible to create a temperature that is a few degrees below the air temperature in the house – ideally 5-8 degrees below the current room temperature. By controlling valves and pumps, cool liquid from deeper layers of earth is sent through the underfloor heating system.

What is needed in addition to a heat pump?
In addition to the cold source, it is necessary to have a look at the control unit and the hoses incorporated in the floor. A dense pattern of the pipes is recommended for floor cooling. The overcapacity that results for the underfloor heating must be compensated by the control unit.

Have I ever heard that condensation can form during floor cooling?
When the temperature of the floor cooling is set too low, the floor can feel uncomfortable to walk on. There is also the risk of condensation forming. Pay extra attention to this if you have parquet floors! Wood does not tolerate water well and the planks may warp.

How nice would it be if your home would stay cool?
