Hello everyone,

After a long search, we have finally come across a new build offer that might be suitable for us.
We now want to arrange an appointment with the provider, so I am gathering questions to ask them.

Among other things, the building description we already have states that an "air heat pump with direct condensation" will be installed (ECO – 6 LA DK by Bartl).
What exactly should I understand by that? Is it an air-to-air heat pump or an air-to-water heat pump, or something in between? Does anyone here know about this? Does it make sense?

I am still completely unsure about this topic...

Hello,
this is an air-to-air heat pump. It is called direct condensation because the heat is transferred directly to the buffer tank via the refrigerant line, without the detour through another water line.
I have had an ECO-5 LA DK for a few weeks now (as a replacement for a Tekalor heat pump that broke down after 11 (!) years. Apart from the quality and heating performance of the old system, I was far from satisfied with the service).
The Bartl heat pump works great. However, we still need to adjust the settings a bit. At temperatures just above freezing, the house (150 m2 (1,615 sq ft)) is still much too warm.
