exto1791Hello everyone,
We are currently in the planning and decision-making phase and need to choose a company.
Now, regarding the topic: air-to-water heat pumps.
Unfortunately, the general contractors are not sufficiently knowledgeable and can barely answer detailed questions here. I will also be meeting with a heating installer soon to get advice on this matter.
Nevertheless, the two companies offer two different models included in their proposals. For comparison, the following questions come to mind for me:
1. Are both air-to-water heat pumps eligible for BAFA funding?
2. Which air-to-water heat pump is generally better suited for our single-family home?
3. Which estimated value of the pumps should be considered higher, since I need to bring both offers to the same level?
The following models were offered to me:
Viessmann Vitocal 200-S and Viessmann Vitocal 300-A (AWO-AC 301.B)
I appreciate any information!

1. This cannot be answered directly; it needs to be calculated individually for each model. Try searching online for an annual performance factor calculator related to BAFA funding.
2. This cannot be answered as no information about your house is available, and there are different performance models/types. However, there seems to be a slight issue of “oversizing.”
3. What do you mean by value assumption? What can be said is that there are two different types: one is split, the other monoblock. Research the difference.
Is there already a room-by-room heating load calculation? Otherwise, the offer is basically useless and more of an estimate.

Regarding point 2, the answer is probably: It depends No heating load calculation or similar has been done yet, so this is definitely an estimate.
Therefore, the question is whether the price difference between the two pumps can already be determined? I strongly suspect that the 300-A model is generally more expensive than the 200-S. Thus, the cost estimate for the air-to-water heat pump at company x is higher than at company y.
How is a heating load calculated? Can this be done based on the floor plan?
