Can the wood stove additionally be equipped with a buffer storage tank?

Hello community,

I am troubled by a question during the planning of the energy supply for our single-family house (new build).

Since my hobby is forestry work and I will always have some firewood in stock, I want to integrate a wood stove into my house in addition to the heat pump (Dimplex LAW 9IMR). This was offered to me by the heating engineer I trust.

Now I am considering whether it is worth equipping the wood stove with a buffer tank and connecting it to the water system to relieve my air heat pump.

I like the wood stoves from the local company Schiedel very much visually, the KINGFIRE model has somewhat won me over. Now there is also a AQUA version, which already includes a buffer tank. Do I see it correctly that I would not then need an additional one? My heating engineer has estimated the connection of the wood stove in the regular version to an additional tank at about 2000 €. Per kW heating power, 50 liters more buffer storage.

Unfortunately, I cannot assess to what extent the additional costs pay off in the medium or long term. Our budget does not allow for much more.

Sorry for my amateur questions :)

Regards

You probably will never really save in my opinion. Even using the wood consumes operating materials etc. Additionally, the increased installation effort, necessary regulation, etc. Two options: 1. Completely do without, save the chimney and the associated chimney sweep and sell the wood 2. Install a small wood stove without water and realize an open design of the ground floor

Your heat pump has ~5KW. So your heating load will be somewhere below that. The stove has 7.6KW, of which 3.4KW end up in 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 water-bearing wood stove only makes sense in old buildings, or in newly built old buildings. Not in modern houses. The energy on the air side cannot be removed in well-insulated houses.

Thank you very much for the quick answers. I think they helped me with my decision-making :)
