ᐅ House with 180 m² => RecoVair VAR 260/4 or better 360/4?

Hello everyone.

Our new build will have exactly 181 m² (1,950 sq ft) of living space.

According to the specifications, the Vaillant recoVair VAR 260/4 (up to 190 m² / 2,045 sq ft) should be sufficient. However, we are wondering if it might still make sense to choose the larger model (RecoVair VAR 360/4, up to 290 m² / 3,120 sq ft)?

1. Would the larger unit possibly operate more quietly because it would run under less load?

2. What about the electricity consumption?

... What do you think?

1. Yes, because the smaller one will almost exclusively run at full load, assuming the house is also occupied.

2. You would need to take a closer look at what components are installed, etc., but it should be roughly the same.

This question comes up every few weeks and is usually answered by saying it is generally better to choose the larger one. Above all, living area is not the same as usable space, and both need to be properly ventilated.

I spoke today with a technical support advisor from Vaillant. He said that the smaller one is actually quieter ... ??? Can that be true???

Hello Christian,

may I ask how you ultimately decided?
What has been your experience with the choice so far?

Sorry for digging up your post from 18 again 😀

For 153 m² (1,646 sq ft) of living space, the RecoVair 260/4 should be sufficient, right? This is the model our general contractor mentioned.
