ᐅ Individual Room Control with Cooling Function (Is Underfloor Heating with a Water-to-Water Heat Pump Practical?)

Hello everyone,
our plumbing specialist wants to know if we want a cooling function for the underfloor heating’s individual room control.
My husband doesn’t want cold floors, while I personally hate heat inside the house. We’re wondering how effective this cooling function really is, whether the floor actually feels unpleasantly cold, and if the investment (not really significant – 900€) is worth it. We plan to fully glue down 10mm (4 inches) solid hardwood flooring (vertical grain) in the living areas.
Looking forward to your opinions.

As box mentions, individual room controllers are generally not necessary with a heat pump, and you can also use it for cooling. However, if you want to use it as it is built, you will need the specific controllers for cooling.

I also have an air-to-water heat pump but without individual room controllers. In summer, I manually close off the rooms with tile flooring to cool, as otherwise it gets quite uncomfortable. For the bedrooms, though, it works well.

Ah, I had understood that you have a ground source heat pump, meaning passive cooling is possible (in that case, it’s a no-brainer for me to choose it). For active cooling with an air-to-water heat pump… I have no experience with that.

Personally, I do exactly as the previous poster mentioned. In summer, I keep the rooms with tile floors closed (in our case, only the bathrooms, as I dislike tiles in living areas) because they tend to get uncomfortably cold. Parquet flooring, on the other hand, results in really pleasant temperatures for my feet during summer.

We don’t have individual room controls either, since in a modern house they only reduce the heating system’s efficiency without adding any noticeable comfort (quick adjustments are not possible with underfloor heating anyway). We have a central control unit in the living room, which also includes a dew point monitor (which you definitely need).

As for the technical implementation of individual room controls… unfortunately, I can’t help you there, as I’ve never looked into it.
