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.

I have an instantaneous water heater installed at the sink, along with a small electronic device that switches off the heater as soon as the inlet temperature rises above 30°C (86°F). The cost is about 150€. This way, there’s no cold water when washing hands in the morning or at night. It’s an affordable alternative to a circulation system.

It would be better to use a timed circulation system instead.

daniels873 Oct 2015 12:59Let the original poster decide whether this information is relevant for them. Not everyone has four bathrooms or the need to have warm water instantly at every tap in the entire house from the first second.
Also, I wonder how time-controlled circulation works if you need to use the toilet at any random time during the night. It’s always very awkward if the man comes back to bed with cold hands. Besides, the water feels coldest at night. During the day, I don’t mind waiting 10 seconds for warm water in the kitchen.
