Hello Community,
I have a question regarding the energy supply planning for our detached house (new build).
Since my hobby is forestry work and I will always have some firewood stored, I want to integrate a wood-burning stove into the house in addition to the heat pump (Dimplex LAW 9IMR). This was recommended to me by my trusted heating engineer.
Now I am wondering if it is worthwhile to equip the wood stove with a buffer tank and connect it to the water heating system to reduce the load on my air-source heat pump.
I like the look of the wood-burning stoves from the local company Schiedel, especially the KINGFIRE model. There is also an AQUA version, which already includes a built-in buffer tank. Am I correct in assuming that I would not need an additional buffer tank in that case? My heating engineer estimated the connection of the standard wood stove to an additional buffer tank at around 2000 € (approximately $2200), recommending 50 liters (13 gallons) of buffer storage per kilowatt of heating output.
Unfortunately, I cannot assess whether these extra costs will pay off in the medium to long term. Our budget is quite limited.
Sorry for my amateur questions 🙂
Best regards

In my opinion, you will probably never really save much. Burning wood also consumes operational materials, etc.
Additionally, there is increased installation effort, necessary controls, and so on.
Two options:
1. Completely do without it, save on the chimney and the associated flue cleaning, and sell the wood.
2. Install a small stove without water connection and implement an open layout on the ground floor.

Your heat pump has about 5kW. So your heating load will be somewhere below that. The stove has 7.6kW, of which 3.4kW is released into the air. Probably more.
Imagine that all the energy your house needs for hot water and heating is released into the air in the living room. A wood-burning stove with water jacket only makes sense in older buildings or in newly renovated older buildings. Not in modern houses. The energy released into the air cannot be removed in well-insulated houses.
