Hello everyone,
Our heating engineer said he would usually install a circulation pump, but it could also be omitted. Operating costs would be about 30–50 € per year, and he estimated that it would need to be replaced every 6 years.
Of course, we don’t want to wait 30 seconds for the first warm water. He also mentioned that he can reduce the pipe diameter to somewhat lower the wait time.
Does anyone have experience with these pumps – from what pipe length or distance would you recommend installing one?
Another topic was the ventilation of the utility room, bathroom, and kitchen – he said it might be possible to install an air admittance valve (also known as a "mushroom valve" or similar) to avoid venting through the roof. Does anyone know about this? Does it cause any odors? I find that hard to imagine.
Thanks and best regards.

Doc.Schnaggls26 May 2015 09:01@Lexmaul79 : The pump has its own control system. I’ll check it this evening and let you know. Unfortunately, I don’t have the data memorized...

Maybe I would then wonder why the rule needs to be explained over and over again – it obviously isn’t entirely clear. These "well-meaning" comments usually come from the type of user who wants to blur the line between "their own" and "someone else’s" living room; topped off with the attitude: "wash my fur, but don’t get it wet!"

Sebastian7926 May 2015 10:52Sorry Bauexperte, how many times do I have to say that I have no problem with the rule because I accept the right to control access to private property? At some point, you start to feel like you’re being taken for a fool...
@Doc.Schnaggls : Could you please send me a private message with the manufacturer of this self-learning pump? Thanks!
My wife works as a nurse in a three-shift system with irregular shift changes. A pump like this might be better than one controlled only by a timer with weekdays.
We are not living in the house yet, but we will start moving in this week. That’s why the pump is currently turned off, and so far it takes about 20 seconds to get hot water. That’s still bearable, but if we could wait less during certain times (for showering, etc.), it would be a real improvement in comfort.
