Hot water tanks

[ClaireRob]

Hi

We have a hot water tank downstairs and a downstairs bathroom only.

We have cold water tank or possibly 2 upstairs.

We wish to put an ensuite upstairs without changing the heating/boiler system.

Is this possible to push hot water upstairs pressure wise??
Thanks

You need a negative head pump.

The hot water cylinder is fed from the large upstairs/loft tank, so it will push water up to first floor level. Do not expect good performance though, especially from a shower, as the pressure is dependant on the height of the cold water cistern above the outlet.

Ah - BTW - I'm assuming the new bathroom is above the cold water cistern.

Hi
Thanks for the reply’s

So the house upstairs bedrooms are already in the roof space, not a conversion, built like that from the offset. The cold water tanks are in the eves and the shower room would be on the same level.


A shower could be made more powerful With a pump?

I’m not fussed about a hot water tap performance as much to be honest.

Given your setup, a shower, and probably the basin taps, would not work at all without a negative head pump.
