Hello everyone,

we are planning the construction of a prefabricated house with Kfw 70 standard. The house is to be heated primarily by gas/solar (water), partly with underfloor heating and partly with regular radiators. In addition, a controlled residential ventilation system is integrated in the house, i.e. a controlled residential air ventilation with heat recovery.

Furthermore, since the heat from a stove is simply different, we want to install a stove. I know the technical requirements from my chimney sweep. That means the stove must be room air independent and ideally DIBT certified.

But as it often is, the stove we have chosen is room air independent but does not have DIBT certification. According to my information, then a pressure monitor must be installed that switches off the controlled residential ventilation when the negative pressure becomes too high.

The question I am now asking myself is, what does such a pressure monitor look like and how is it installed? That means, where does it measure? I assume in the room where the stove is located and where else? Does it measure outside? If yes, how do I get the sensor outside? Because drilling an additional passage to the outside afterwards is rather bad because of the sealing.

Can someone bring me up to date here?

BTW: The exhaust hood is recirculation, can be ignored.

Thank you very much!

Hello Phoenix,

the air pressure monitor is installed near the chimney and measures the difference between inside and outside using an air tube, as you feared. Google "Luftdruckwächter" and you will find the most common types, there are surface-mounted and flush-mounted versions.

Regards,
Sebastian

Hi,

ok, I took a quick look, there seem to be wireless models that transmit the signal to a socket which then cuts the power, for example.
I think I need something along those lines.

But what about the hole in the exterior wall? That's not good, right? Because of the vapor barrier.
Or can you go outside through the chimney?

Hello, Sincere condolences for this money pit! Probably a general contractor/general builder offer! Best regards

No!

But why a money pit?

Even most laypeople are familiar with the flow temperatures of radiators (approx. 60°) and underfloor heating (approx. 30°). If I now have to heat something up to 60° only to use 30°, that is inefficient. Either rely completely on radiators or completely on underfloor heating. If you read a few of Euros' posts here in the forum, you will find that most solar systems are probably only added on for the sake of cosmetics for the KfW standard and will actually never pay off.
