Hello,

my heating engineer suggests installing underfloor heating (roughly laid) in my new build’s basement and under the garage (a waterproof concrete structure, approx. 150m² (1615 ft²)) to keep the temperature constantly at 15°C (59°F) in order to prevent mold during the winter.

It’s not just the initial costs for the underfloor heating but also the ongoing operating costs for the heating system (heat pump).

Perhaps mold could also be prevented in other ways, for example with ventilation?

My question is: is this really necessary?

Hello,

sorry, but this is the first time I’m hearing about that.

In our basement, we have underfloor heating installed in the hallway area and the guest room – the other three rooms (utility room, hobby room, and storage cellar) are without heating.

We didn’t have any mold issues during the first winter – however, it is advisable to regularly ventilate the basement to remove construction moisture.

I would rather recommend planning a mechanical ventilation system with heat recovery for the basement rooms as well.

Regards,

Dirk

In our basement, the temperature stays constantly at 15°C (59°F) without heating, even when it is -15°C (5°F) outside. If the basement is properly insulated and constructed, you shouldn’t have any problems without heating.

Is the garage included within the insulated building envelope, including the insulated door? If not (which I assume), then the underfloor heating for the garage will probably cost about the same as for the entire house.

Alternatively, I can stand next to the garage once a month, and you can just hand me 100 euros. That’s roughly just as reasonable.

More information is needed to answer this question!

Is this purely a utility basement, or is it within the thermal envelope and partially or fully used as living space?

No, it is planned purely as a utility basement.
