I would be interested in your experiences with this, including model, function, mounting location, etc.
Physics naturally causes the warm air (mostly heated by a fireplace here) to rise initially into the rather large gallery, where it first gets warm. Meanwhile, we now use these fans directly on the chimney pipe, which I was initially rather skeptical about. Nevertheless, it now works so that it is less warm upstairs, meaning more heat stays downstairs, so it works well.
Our IR heater sometimes switches on as well, but we only have it set as a kind of basic security.
We rarely use the "air heat" from the air conditioner, for example when I am sitting upstairs and want it to get warm quickly; then 15 minutes of power mode and it's fine; otherwise, it is used as an air conditioner in summer.
We also have Kfw40 or even better, and in my opinion, we really need very little heating costs; however, I believe this only works with such individual usage behavior, just as with a stove, otherwise the temperature can quickly go wrong.
In the previous apartment, we had underfloor heating and planned to have a fireplace; we rejected it because it often got too warm when the sun suddenly came out outside.
Likewise here, I think we have a similar model, also with domestic hot water heat pump, and I find it overall extremely economical.
Exactly. The individual situation on site is of utmost importance (insulation, windows, solar gain, etc.) and therefore it is not so easy to compare. Additionally, individual user behavior and perception always play a role. For example, I prefer it cooler rather than too warm.
1. In the living room about 2m away from the wood stove
No idea about the model, it was one that was advertised as very quiet, 1.32m span width with LED light
Usage behavior: Fireplace on for about 1 hour until the room temperature reaches about 24-25 degrees.
The surrounding rooms hardly received any heat at that point.
The fan then pushes the heat downward.
Room temperature rises rapidly as the accumulated heat is pushed downward.
At the same time, due to the greater temperature difference, it pulls in cold air.
If the fan is set too high, you feel a draft.
The fan then runs for about 3 hours even after the fireplace is off.
Otherwise, the heat would accumulate again at 2.5m height.
Room temperature starts at 28 degrees and then drops to 23 degrees within 2 hours, with hardly any temperature differences to the other rooms.
All fireplace flaps should then be closed, otherwise cold air is sucked into the house (negative pressure).
Since the stove has soapstone all over, only this variant with electricity was possible, and I also consider the small ones that can be placed on a plate to be not very effective.
2. Also as an air conditioner, the air-to-air heat pump is a joke. It supposedly has 800 watts of cooling capacity.
A forgotten window triple-glazed on the summer south side and the house is stuffy warm.
The consideration is to install a normal split air conditioner here.
