Hello,
we are currently building a KfW40 Plus house. The house will be so well insulated that we will need a maximum of 15 kWh/m² (1.4 kWh/sq ft) heating energy per year.
At the moment, we are considering whether to install a nice fireplace. The issue is that it requires a high-quality masonry heater or storage fireplace, which releases only a small amount of energy immediately and stores the rest, then emits it evenly over many hours as radiant heat.
We have two quotes so far, ranging from 15,000 to 20,000 euros per fireplace. The negative pressure monitor, which is also necessary (we have a ventilation system), is not yet included in this cost.
My question is: who has a very well-insulated house and a fireplace? How often do you actually use it? Do you experience any problems with overheating in the rooms?
What is your opinion on this? Should we plan for it or leave it out?

Umbau-Susi11 Mar 2016 09:11We don’t have an "energy-braked" house, but we use a Lotos M3, which can also operate independently of the indoor air. It runs daily in winter and during transitional seasons. It contains 600 kg (1,320 lbs) of soapstone for heat storage and can be switched between convection heat and stored heat.
Hello everyone,
I just came across the pictures of the stoves in this thread with great interest and have a few questions:
Water-heated?
Custom-built or from a stove fitter?
Manufacturer of the fireplace inserts?
Exact construction of the cladding?
Since I am also considering installing a fireplace insert with suitable cladding as a room divider, I would be very grateful for some information.

Since I am also considering installing a fireplace insert with appropriate cladding as a room divider, I would be very grateful for some information.For us, the fireplace was completely installed by the fireplace builder. The firebox is from Spartherm—I don’t have the exact model name on hand, but every fireplace builder knows it.
The design is purely for aesthetics, without significant heat storage or water-cooling.
It was built using drywall construction techniques, but with the appropriate boards for fireplace construction (heat-resistant/fireproof). This allows for any design, including niches and similar features—for example, our niches (on both sides) also have LED lighting from above.

nordanney20 Mar 2016 09:26We had Fireboard panels from Knauf installed, and the chimney also needs to be protected from the heat with a board (I do not have the exact name for it). Other than that, it was standard drywall construction.
I don’t have individual prices – the total gross price was €9,834.00.
