Ventilation system in the new building

Sure, 99% is better, which system is supposed to achieve that?

Hello bangolo,

The TZWL Dortmund shows up to 200m³/h 99% heat provision rate
falling to 95% heat provision rate up to 275m³/h.

I would need to look up the information again in the article.

The specialist group Building and Energy already confirmed 95% in 2003.
That is how I came across this company in the first place.

Best regards

Yes, the 60 to 85% in the article seem to generally refer to exhaust air heat recovery. I would say we just leave the numbers as they are.

Hello,

what price should I expect for a complete heating system with installation including controlled ventilation?!

I'm not concerned about 100 euros here - just a rough estimate for a 160 sqm new build - prefab house...

Thanks!

Regards, Mathias

What price do I have to expect for a complete heating system including installation with controlled ventilation and exhaust?

A good question!
That depends on many parameters. In particular: the energy status of the building, climate location, usage habits, etc.
In some cases, a ventilation system is not necessarily required.

Which heating system do you mean?
