Hello everyone,
I have always been keen on an air-to-water heat pump combined with a central ventilation system, for example, the Stiebel Eltron LWZ 504.
But what is your opinion if both options were possible (there seems to be hardly any price difference, especially due to subsidies)? Which option would you choose?
A trench collector for a brine-to-water heat pump plus central ventilation, or the above-mentioned air-to-water heat pump plus central ventilation as a combined unit?

With everything included, it is now costing me about 800 euros (around $860) more than gas.
Of course, this calculation only includes the 5,000 euro (about $5,400) BAFA subsidy.

With everything included, it now costs me almost 800 euros (about 860 USD) more than gas.
This, of course, only considering the 5,000 euro (about 5,400 USD) government subsidy. Could you please list the cost items roughly, so I get an idea of the price? Which brine heat pump model did you choose?
