Water cylinder/pump in the utility

dellas1979

Nearly at the plumbing stage of a new build. I dont have an attic.

I was originally supposed to have my cold water tank in a shed outside the house. Water would be pumped in.

The builders have come up with an idea (rather than constructing a shed/insulating it, lights to ensure water doesnt feeze - estimating it would cost about 4k).

Their suggestion is to put the heat recovery system on the wall of the utility. Have the water cylinder and pump under the recovery system.

My concern is would be if there would be a crazy loud or constant noise off the pump?

Name of the pump is Multiboost.

You paid for an arch, What did your arch say?

Yep they said it's an option.

I am worried about noise though, which is very individual to a person.

Anyone used the multiboost?

Effects

We have a water tank under our stairs, on a concrete floor, with a pump. The noise drives me bananas and I wish we had put it outside now.
We had little consultation with our mech engineers unfortunately and I didn't think it would be as bad as it is. It doesn't bother my partner at all though.

Leave cylinder inside the conditioned space, also shorter pipe runs.
put pump out side if possible.

you mention the cold water tank, where is that now?
However the noise issue is really only at night, the problem you have is that if the cold water tank is at ground level, then you will need to pump everything, when I spec this stuff, I leave the ensuite toilets to be fed from the tank in attic by gravity, hence no noise at night when you are dealing with the effects of an iffy takeaway or bad pints

It very much depends on your layout, if you have any bedrooms next to or above the utility I would moved the pump out if at all possible, if you only have other utilities like bathrooms, en-suites or circulation space next to or above the utility then you could consider keeping the pump inside, however be under no illusion you will hear the pump every time. I have it in my utility but have nothing adjacent to the utility only bathrooms and circulation space and the noise level is only barely acceptable TBH.

I have my en-suite done like that but the taps needed to be pumped as there was not enough pressure from the attic tank to provide much more than a dribble out of the taps (single story house) so while it is a good idea the tap voids the noise canceling benefit of it, the real reason I did it that way was to have at least one toilet working in the event of a power cut.

Thanks for all the replies!

I dont have an attic (its a vaulted ceiling to the roof), so that is not an option to put tank there.

Utility is beside kitchen. And above is small bedroom.

The pump (in the link above) says its the quietest on the market! 63db. The pump is in the tank itself (not outside).

I have asked the builders can they put me in contact with someone who has used this pump/tank system.

When you say put the pump outside, surely you couldnt have the cold water tank inside in the utility and the pump outside (utility has 2 outside walls)?

Effects

The pump in mine is in the tank itself. It's 83dB. It's vibration that's annoying as well, not just the sound of the pump.

We're in our new build 1 year. We have a 500l tank in the garage with a submersible pump in it. From this pump we've a 1"HG hydro pipe running into the hot press which pressurises everything. You'd never kno someone was showering, my parents have their pump sitting on the upstairs floor in the hot press and it would deafen you. Personally I hate the sound of a washing machine or dryer, even the dishwasher winds me up a bit but that's just me. Imo go with the external pump.
