Hello everyone,
we are currently planning our new single-family house. We are building a solid house (MZ7 stone); in terms of standard, we will probably achieve Kfw55 / Kfw40.
So, it is a well-insulated house. We are a household of 4 people.
For the heating system, I am planning a wood insert stove (on the ground floor) with a water jacket. In terms of output, it will probably be a stove around 10KW with a water portion of up to 70%.
A solar system (15-20 sqm) will be installed on the roof, which is intended for hot water and heating support. We want only one storage tank. So, a buffer storage tank with an integrated domestic hot water tank (coil in the upper area).
An electric heating element will also be installed in the buffer storage tank, which is intended for emergencies. In case we have no sun and do not want to heat with wood.
About 200 sqm of space need to be heated. We have underfloor heating throughout the house.
The solar system goes on the roof (southwest orientation). We have a total of 40 sqm available here. The rest, which is not needed for hot water, we will equip with photovoltaic modules for electricity generation.
I wanted to ask who has experience with such heating concepts and maybe has a few tips for me.
What do you think, is the output of the stove sufficient?
How big should the solar area be?
How many liters should the buffer storage tank have?
Thank you very much for your help.
Regards
Michael
