Does it make sense to install a heat pump in a newly built single-family house without a photovoltaic system, or would the electricity consumption be too high? We were considering an air-to-water or water-to-water heat pump.
Well, it will also take a few hours; it doesn’t go really fast. But it is faster than with the heat pump.
When I look at the development of fossil fuels and electricity prices, the heat pump is immediately out. Not even politicians and their ideas can help with that...
And heat pump plus photovoltaic is a great solution. I also prefer driving a luxury car rather than a basic model. The only downside is that I can’t afford it.

I don’t turn up my gas heater a few hours before showering either...
Heat pumps are often found in new buildings due to climate policies. Previously, the thermal insulation calculations were often far too poor.
With the Energy Saving Ordinance 2014, the regulations introduced a new primary energy factor because there were no significant improvements in the efficiency of heat pumps.
Now, almost anyone with a heat pump can provide proof of thermal protection.
A hundred years of poor efficiency remains poor efficiency.
Photovoltaics are a commercial investment and are not more efficient; storage solutions have not been resolved.
Unless one stores energy in batteries, but that is a contribution to climate protection.
Ultimately, we can only hope that something better and especially more sustainable with a longer lifespan will be developed in the future.
Gas cannot score points here either,...

We were thinking of an air-to-water or water-to-water heat pump. In theory, it makes sense because it produces more heat than pure electric heating, but it is still an electric heating system. Air is a poor heat source. Ground loops or deep boreholes are better.
The initial investment is higher than for gas. Low flow temperatures and large heating surfaces (underfloor heating or wall heating) are required. Some heat pumps can both heat and cool. Photovoltaic systems can reduce electricity demand but increase the investment cost.
In some housebuilding projects, you can get a ground-source heat pump at no extra cost compared to gas. An additional solar collector, as used with gas systems, can be omitted. We have a ground-source heat pump with a direct expansion system.
