PhoenixDH16 Jul 2013 09:23Hello everyone,
we are planning to build a prefabricated house meeting the KfW 70 standard.
The house will be heated primarily with a gas/solar (water) system, partly with underfloor heating and partly with conventional radiators.
In addition, a controlled residential ventilation system with heat recovery will be integrated.
We also want to install a stove, since the heat from a stove has a different character.
I am familiar with the technical requirements from my chimney sweep.
This means the stove must be room-air independent and ideally certified by DIBt.
However, as is often the case, the stove we have chosen is room-air independent but does not have DIBt certification.
According to my information, a pressure monitor must then be installed, which shuts off the controlled ventilation system if the negative pressure becomes too high.
My question now is: what does such a pressure monitor look like and how is it installed?
Where does it measure? I assume in the room where the stove is located, but where else?
Does it measure outside? If so, how can I route the sensor outside?
Retrofitting a penetration to the outside later would be problematic due to airtightness concerns.
Can someone bring me up to date on this?
By the way: the range hood will be recirculating and can be disregarded.
Thank you very much!

Hello Phoenix,
The air pressure sensor is installed near the chimney and, as you suspected, measures the difference between inside and outside air pressure using an air tube. Search for air pressure sensors online, and you will find the most common types. There are versions for surface mounting and flush mounting.

Sebastian

okay, I had a quick look, and 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 can’t be good, right? Because of the vapor barrier. Or can you go outside through the chimney?

Hello,
Best regards

....The house is basically going to be heated with gas/solar (water), partly underfloor heating and partly regular radiators.

But why a money pit?

Even most non-experts are familiar with the supply temperatures of radiators (around 60°C (140°F)) and underfloor heating (around 30°C (86°F)).
If I have to heat something up to 60°C (140°F) just to use 30°C (86°F), that is inefficient. It’s better to either rely fully on radiators or fully on underfloor heating.
If you read some of Euros’ posts here in the forum, you will notice that most solar systems seem to be installed mainly to meet the KfW standard cosmetically, and they will probably never pay off financially.
