ᐅ Controlled residential ventilation / DIBt-certified stove / pressure monitor

Hello 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!

And ypg... You don’t buy car insurance for a Bentley if you’re only driving a Polo.

Bad example from you, Milambar.

If I plan to install a wood-burning stove in my single-family house, I am opting for a higher level of comfort beyond the standard. The mechanical ventilation with heat recovery also adds to that!

Maybe an example to consider is that both Bentley and Polo have airbags: regardless of the engine size or body type, airbags can protect accident victims from fatal injuries.

What are we talking about? About 1500-2000 Euros... How expensive is the stylish "Le Camin" in the center?

Boergi, if your home savings contract requires DLW, then of course you are in a difficult position and have to install it.
I just find it amusing that it is handled differently everywhere; when I asked about whether I “needed” something like that, my home savings contract immediately asked what I intended to use it for, because it was unnecessary.

But okay, your home savings contract just makes its own rules.

Exactly that...
If all safety regulations are already met, additional safety measures are nice but should remain optional.
Of course, wearing two helmets at the same time might offer better protection, but one is the requirement.

As I said, I find it interesting how BSFs can simply decide arbitrarily.

Who says that it’s a nonsense technique? No one has claimed that so far.
It’s simply a question of whether it is necessary from a technical perspective and from the chimney inspector’s point of view.

@nordanney and Milambar:

To be honest, I’m also annoyed about the $1500 for the pressure switch... we found a nice certified fireplace, not even expensive, with all the paperwork included.
Still, I accept the decision about the building savings contract and stay calm, because maybe it will pay off someday without me knowing... I pay more just for choosing my tiles...

Even “back then,” when seatbelt laws didn’t exist yet (or during the period when you weren’t fined for not wearing one), there were victims... followed by comments like “if only they had…”

Just try googling carbon monoxide poisoning...

Maybe I’m just professionally biased, being a bit more sensitive about the topic and more relaxed regarding the arbitrariness of the building savings contract.

Isn't it possible to change the chimney? There should be more options available now.
