Hello dear forum,
I am new to this forum and have a question.
Our two-family house (270 sqm (2906 sq ft)) will likely have a wide south-facing side. Because of this, I am worried that it will become unbearably hot inside the house during summer, and we are considering a ventilation system with active cooling.
We plan to install an air-to-water heat pump as the heating system, combined with underfloor heating.
We are still uncertain about installing a ventilation system. If we do install one, it will definitely be a centralized system, not a decentralized one (due to noise pollution from outside). I have several questions:
a) How effective is an air-to-water heat pump combined with a centralized ventilation system with cooling, especially regarding heat recovery? For example, as a monoblock unit? Or a split system (heat pump and mechanical ventilation with heat recovery)?
b) Which combinations or manufacturers of air-to-water heat pumps plus ventilation systems with active cooling can you recommend?
c) How many degrees difference can the new ventilation systems with active cooling provide?
I mean not a ventilation system that only exchanges warm indoor air for fresh outdoor air.
d) Or are ventilation systems not able to compete with air conditioning?
I am already very grateful for any answers!

But air conditioning requires significantly more electricity than a controlled residential ventilation system.Overall, air conditioning does not consume much electricity if operated properly. That means turning it on before it gets too warm and only switching it off once it cools down again. In other words, just let it run. In my partially renovated older house of 140m² (1507 sq ft), this amounts to less than 500 kWh per year.Deliverer schrieb:

So basically, just let it run. For my partially renovated older building of 140m² (1507 ft²), it’s less than 500 kWh per year.That’s exactly right, and we do the same. For about 135m² (1453 ft²), we use approximately 350 kWh per year.
