ᐅ Wood-Burning Stove vs. Low-Energy House – Seeking Experience Reports

Hello everyone,

Does anyone here have a wood stove installed in a low-energy house?

You often hear about overheating because a wood stove is simply oversized for the low energy demand, especially if it is not a water-based stove and therefore not integrated into the heating system. So far, I have been advised to install a storage stove, possibly with double-glazed glass. In terms of size, we are only interested in units starting from 7 kW.

What are your experiences?

Hi,

I also use this combination and haven’t noticed any overheating so far. Why get a fireplace? Exactly, to create a cozy warmth and also add something nice to look at. Overheating probably only occurs if it’s heated incorrectly.

Hi Sunny, how many kW does your storage heater have?

It depends on the design of the fuel cell. In our case, despite having an 11kW fuel cell (we wanted a large fuel cell because we have a see-through fireplace as a room divider), the temperature increase at full firing is only 2-3 degrees Celsius (4-5 degrees Fahrenheit). However, the entire ground floor is completely open-plan (living/dining/kitchen and stairs to the upper floor) with over 70m² (750 sq ft) of space. It was planned so that part of the heat is distributed into the room through ventilation slots, while the rest simply escapes unused up the chimney.

11 kW with two glass fronts in a low-energy house is quite impressive, but it seems to work. Of course, it heavily depends on the room layout.

I would be interested to know whether the 11 kW stove is a dedicated heating insert or if the flue gases are routed through fireclay chimney flues before going into the chimney...

I’m curious whether the 11 kW stove is a pure heating insert or if flue gases are routed through refractory brick flues before going up the chimney...

It is a pure heating insert, which is clad with firebricks on the two sides and the top for safety reasons only, not for heat storage.
