we are currently building a detached house with 180m² (1,940 sq ft) of living space in Bavaria.
We are having an air-to-water heat pump installed, as well as a hydronic stove to additionally generate hot water.
Our construction company said that an 800-liter (210-gallon) tank is completely sufficient, and this has been planned accordingly.
However, another stove installer now says that this is far too small, and that if there are a few cold days, we will have problems and won’t get properly hot water. He also mentioned that a hydronic stove only causes unnecessary costs instead of providing any real benefits.
Does anyone have experience regarding the size of the tank or the hydronic stove?

we were told that (there are 3 of us) a minimum of 300 L up to about 500 L would be sufficient.
Usually, people don’t bathe immediately one after another.
However, after bathing (about 200 L), there should still be at least 100 L left for showering.
The water will already be heated to around 60°C (140°F), which should be sufficient according to guidelines (bacteria protection, etc.) (especially for showering).
