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

Created on: 25 Oct 2015 09:42

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,

Good day,

I have already considered summer thermal protection under the roof (continuous insulation above the rafters with wood fiber boards and mineral wool), but I’m afraid that won’t help in the long run.

There is a principle in our industry that we – albeit rarely – agree on. "You can protect a house against almost anything, but not against heat."

In that respect, I agree with 'Mycraft.' "If you struggle to sleep during hot summer nights like he does, only an air conditioner will help; regardless of whether it is a split system or central air."

I wouldn’t install any if I thought it was sufficient as is – although the amplitude shift is already quite significant.

I’m curious to see how it will actually turn out later... according to the HVAC specialist, the climate in our tiny master bedroom will freeze us out anyway.

That should work out fine... my 3500W system cools the bedroom down to about 21°C (70°F), but since the doors are always open, the surrounding rooms are also cooled and stay around 23-24°C (73-75°F). You can really feel the temperature difference when you go upstairs... and since you have two units, it will work similarly or even better.

No, we have three units on the upper level and one below — but they were selected according to the room sizes.

Only 10m² (108ft²) cool down quickly ;l

How loud are the split units? Can I place them on the garage, which is located on the property line, without any issues, or will the neighbor complain (rightfully/unrightfully)?

If I understand correctly, I should skip the better roof insulation and instead budget around 7,000 euros for air conditioning in two children's rooms, the master bedroom, and the living room? Is that right?
