Hello 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!

Is a monoblock even practical for a single-family home? I already know the differences, but I’m struggling to make a decision...
At first, I would have preferred an indoor installation or a split system, but not an outdoor unit.
What is most commonly installed? What are the current trends?
Could the neighbor be disturbed by noise from an outdoor monoblock? These units are definitely louder, aren’t they?

Mmh... so both are from the same manufacturer. I would suggest asking one to revise their quote to include the heat pump from the other offer so you can compare. But I can tell you right away, a pure "euro comparison" won’t be very helpful.
Because if contractor A just sticks to their usual approach without being open to discussion or uses a standard off-the-shelf solution, it might end up being worse for you than contractor B, who does a proper system design and sizing and tailors the planning to your requirements.

I am also a bit concerned about just letting the general contractor handle the whole thing and not staying involved...
I am considering maybe taking out the "heating" and "ventilation" trades—hence the cost estimates!
That way, I could talk to a trusted installer and get a clean, transparent calculation...
How do you usually approach this?
The heating topic is so confusing. The general contractors (GCs) don’t really want to deal with it either; it probably only gets addressed once the planning is finished and you get closer to the whole process.
But I would never sign such an offer... I need a lot more information here, which the GC can’t really provide. So my question is about price estimates and such, so I can go directly to the heating engineer and have a straightforward conversation.
