We are planning a timber frame house with good U-values for the exterior walls, slab-on-grade foundation, roof, and windows, so we will install a controlled mechanical ventilation system. We are now considering installing a ventilation heating system using technology from Schwörerhaus or a Proxon system from Zimmermann. Additionally, we will include a wood stove (Swedish stove) whose heat in winter can be distributed to other rooms through the ventilation system. With this concept, a traditional underfloor heating system is not necessary.
Now we are questioning whether our assumptions are correct and if this is a good decision. If it turns out to be a mistake, retrofitting an underfloor heating system with an air-to-water heat pump or gas condensing boiler would only be possible with extensive effort.
Has anyone here had several years of experience with a heating concept like ours?
Thank you very much for your input.

Hello,
Whether one solution or the other is suitable can only be reliably determined once specific calculations have been carried out. Until then, it is just speculation.
Before making a decision or signing a contract, these calculations should, if possible, be carried out by an independent expert (MEP planner) who is not involved in the sales process.
Best regards

Koldi schrieb:Air is a poor medium for storing and transporting energy. This also applies to the Proxon comfort technology. Air heating systems only work effectively with very low room and overall heating loads, such as in passive houses or buildings close to passive house standards. However, one should not rely solely on the PHPP heating load calculation in this context, but rather use the DIN 12831 standard.

Hello €uro,
Please don’t take this the wrong way, but your comments seem to suggest that you are trying to create some uncertainty so that your professional group is contacted as often as possible. That is why I did not post my questions here. I had hoped to get some useful information.
Furthermore, I believe your statement that controlled residential ventilation has nothing to do with the building’s exterior components is factually incorrect. Without having your technical degree, I understand that a tightly sealed building envelope makes controlled residential ventilation necessary. I am well aware that a tight building envelope is not directly related to the U-value, but you are unlikely to find a timber frame house with good U-values where the exterior shell is as open as Swiss cheese.
As you can see from my comments, I would have expected from a building professional like yourself some more qualified and, above all, more helpful remarks.
Best regards

Hello,
I am always surprised by what some people expect from a forum. And if they don’t like the answer, they tend to get rude.
Dear Mr./Ms. Koldi, Mr. €uro was simply trying to explain that using a mechanical ventilation system has nothing at all to do with U-values. This assumption of yours was apparent from your initial question.
Furthermore, I interpret the answer to mean that an air heating system is probably not suitable. And what the right concept for your building is can really only be determined by a professional planner on site who performs the necessary calculations.
In my opinion, this is a statement you can actually work with.
The question is, why don’t you have a planner? It’s probably your own concept, and you don’t like that experts are questioning it.
Best regards
