Water-bearing fireplace stove floor heating, heat pump, photovoltaic, new construction?

I wrote that a water-bearing wood stove will be added in winter, so the air-to-water heat pump doesn't have to work as hard.

Do I understand correctly that there is then a water tank to which both the air-to-water heat pump and the wood stove are connected? And if the water is heated by the stove, the air-to-water heat pump automatically stays off?

And for electricity at night, I would of course use an electricity storage system.

So does it make sense to plan in this direction and align the house accordingly during construction?

Good morning,

I did not say that the photovoltaic system is not profitable

Then please excuse me!

Storage systems were simply still too expensive for us (a year ago), did not fit into the house, and for the life expectancy, I multiply by three ?.

The prices for storage media are currently falling quite a bit; the Chinese are flooding the market and thereby forcing the other manufacturers to lower their prices. As far as I know, a lithium-ion battery (is btw. outside) is supposed to have a life expectancy of probably 20 years; at least there are guarantees on the number of charge cycles.

Rhenish regards

In my opinion, it makes no sense to orient your house according to the heat generator and basically as you described, however, this might change if you know the house size, heating load, number of occupants, lifestyle, etc. But once all this data has been determined, the planner will have provided the answer at the same time...

In most cases, a fireplace that can also be used to heat water and the associated piping, etc., is too expensive to be more than just a gimmick.

The house has about 80m2 downstairs and 100m2 upstairs and there are three of us.

Since we want a wood-burning stove anyway, simply because it gives off great heat and the fire is nice to look at, I thought it makes sense to get one with a water jacket to relieve the air-water heat pump in winter, because it uses the most electricity at low temperatures.

And since all the pipes are planned anyway in a new build, I don’t think there will be significant additional costs.
More likely in an old building if you want to install the whole thing afterwards.

Or am I seeing this wrong?

It would be nice if someone who really knows could give me advice.

In January I will also ask an installer about it.

I think you will only get into more trouble there.

1. The regulation becomes significantly more complex
2. You need a larger water tank. Otherwise, you have a lot of heating energy that goes to waste. If the stove is not on, the heat pump has to heat the tank.
3. The additional tank requires more space
4. The stove is significantly more expensive

I would carefully calculate the economic viability.

Why do I need a larger storage tank with an oven?

Can't the oven simply help heat the warm water storage tank of the air-to-water heat pump?
