ᐅ Control the climate using underfloor heating or through the ventilation system?

Hello everyone,

We are considering installing an air conditioning system to cool the house during the hot summer temperatures (which now usually last for a solid 2 to 3 weeks per year).

Has anyone installed an air conditioning system and can share their experience? Do you cool via the underfloor heating system or through the ventilation system?

Best regards,

You can’t really use underfloor heating for cooling, otherwise you’ll have a dew point problem. The ventilation system also doesn’t really work for cooling—you need to install a separate air conditioning system.

So, does that mean you can’t use the ducts of the controlled mechanical ventilation system to distribute cold air in the house? How is air conditioning typically installed in single-family homes nowadays? Hopefully, it doesn’t look like a hotel room unit in Mallorca?

We currently have no cooling system in the house. Our heat pump can provide some cooling in the summer (through the underfloor heating), but it only lowers the temperature by one to two degrees, so we decided against using it because of the parquet flooring installed almost throughout the house (possible risk of condensation moisture).

I know a family who had additional ducts installed next to the ventilation ducts for the bedrooms. They now have an air conditioning unit connected to these. It’s not noticeable in the rooms, as there is simply an extra opening in the ceilings.

We have installed, or are currently installing, air conditioning—one unit in the living room and three in the respective bedrooms and children’s rooms.

And yes, they are Malle units, although the devices look more elegant than bulky. I’m still deciding between high-gloss white and high-gloss black for the color.

I’m not sure if we really need air conditioning despite the over-rafter insulation and mineral wool, but I didn’t want to regret it later.

Air conditioning via the floor is an additional feature, but it cannot replace an air-based system. As for controlled mechanical ventilation, that has already been discussed—so the only options left are Malle-style or monoblock units.

Thank you for your explanation. How much does something like this cost per unit?
