Hello everyone!
Our plumber asked us if we would like to have a circulation pump installed in our hot water system.
The heating system is located in the attic.
- Is this considered standard practice nowadays? Or is it no longer necessary?
- What are the electricity costs and resulting gas costs for running such a pump?
- How much water can I actually save by installing it, and is the benefit really significant?
The additional cost for this would be 300€.
- Is it worth it or not?
I’m always excited about these kinds of “features” in the house. My wife is more skeptical because she doesn’t see much added value, and she thinks we should invest the 300€ elsewhere.
What do you think?

With good planning, it is not necessary in a single-family house. With poor planning or a very large house, it is certainly something to consider.
Take a look in the pink forum (in the building services section, where all the experts are), where it is generally discouraged due to the increased risk of Legionella and energy waste (heat loss is significantly more than the small amount of electricity used by the pump). It won’t break the bank, but many people also pay attention to a certain level of environmental friendliness in their homes. With good planning (short distances and properly sized pipes), the water heats up very quickly even without it.

It is definitely a circulation pump. The pipe is already installed because I hadn’t decided by the plastering date whether I wanted a circulation pump or not. That’s why our plumber went ahead and installed the pipe. Now I still have time until the screed to tell him whether to connect it or not...
He mentioned that the pump has an integrated timer.

Well, if the pipe is already installed, I would definitely do it.
I also wonder how this is supposed to work in terms of hygiene. The circulation is connected to the hot water pipe, usually at the last fixture.
If no pump is installed and the system is filled, the water will remain standing in the pipe permanently. I wouldn’t recommend that...

I agree... When the pump is off, it takes ages for hot water to reach our kitchen, and we end up wasting 4-5 liters (1-1.3 gallons) each time. When it’s on, we basically have instant hot water everywhere in the house. I also control it with a timer switch, so it’s off during normal weekday working hours.
We only skipped this in the guest bathroom downstairs because it is right next to the utility room (4-5 meters (13-16 feet) of piping), and it still takes about 20 seconds for hot water to come through. That can be really annoying... it may not sound like much, but when you turn on the tap at the sink, you really notice how long that wait feels.

If no pump is installed and the system is filled, the water will remain stagnant in the pipe indefinitely. I wouldn’t recommend that...Please also read the last post carefully...

Even the furthest fixture in our house doesn’t take nearly that long... The relatively close guest toilet takes about 3 seconds.
This is what I mean by proper planning... If it is done poorly, it has to be compensated for. I wouldn’t accept a 20-second wait time either.
