Hello everyone, I already briefly mentioned in my introduction post that my wife and I have big building plans, which we hope to finally realize within the next few years. I don’t know anyone in my close circle of friends who is building a house, so I’m hoping to get some help here, as I naturally have a thousand questions about various topics! Currently, we are focusing a lot on how we want to heat our home and have quickly agreed that we want a heat pump for both heating and domestic hot water. I find the topic very complex, but if I understand correctly, a heat pump mainly uses renewable environmental energy, but also consumes a small amount of electricity. That’s why we would like to combine it with a photovoltaic system. Does anyone here have experience with this and can share their insights? Do you think this is a good idea? I would be grateful for any input!
We also want an (air) heat pump, but initially without photovoltaic panels. We plan to wait until energy storage options improve and make it more worthwhile. The electricity costs of modern heat pumps are quite reasonable.
My parents have had an air heat pump for several years now (from a time when they were not as advanced) combined with a water-based fireplace... it is turned on around 0°C (32°F), making even this "old" heat pump worth using.

We do not have a photovoltaic system. If the pump operates at maximum capacity, you will not have any electricity from the photovoltaic system without a storage unit.
Otherwise, try searching for “self-sufficient with passive house.”
There, you will find detailed data for a single-family house.

A photovoltaic system will not be able to sufficiently support the air-to-water heat pump during winter (from early November to late February) at all, since only 10% of the summer output is generated from the roof in winter, and the air-to-water heat pump requires the most electricity during winter.
The combination does make sense, but not in this context.

Look into a ground-source heat pump. In my opinion, it is currently the best alternative. For the drilling, you can get an innovation grant of 4500€ + 500€ from BAFF, which basically covers the cost of the drilling, allowing you to heat affordably. The heat pump costs about the same as an air-to-water heat pump. Best regards
