ᐅ Hot water circulation pump

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.

Most people probably consider the cold water that comes before the warm water as waste. However, it is often overlooked that avoiding this actually leads to much higher costs than the cold water flow itself...

It depends on the production method—and I consider water to be more valuable.

However, that should not be the main argument—my focus is on the aspect of comfort.

The water is not lost, after all...

I don’t know, but I’ve read it often enough by now.

Thank you for the prohibited ( ) link – but it is just one perspective and is based on the idea that this does not help the regions suffering from water shortages.

Okay, then we can continue to waste our food in abundance – which also doesn't really help starving people when my half-full container of quark ends up in the trash.

As mentioned, the main idea of saving the most precious resource was rather secondary.
