PUMPING HOT WATER INTO ATTIC EN-SUITE

[MAGNETIXUK]

Hello all - what is the easiest way to pump hot water into my attic en-suite ? I have a bath and basin to feed. Thanks in anticipation....
Oh, by the way... I have a regular boiler feeding a Hot water tank to the first floor.

If your cold water storage cistern is lower than the attic en-suite outlets you will need a negative head pump.
If it's above the en-suite outlets you will need approx 0.7 litres a minute of gravity flow through the outlets to make a positive head pump work, although this varies with different makes of pump.

Hi - the cold water tank is also in the attic at floor level - would this need the pos. or negative head pump ?
Thanks.

If the cold water tank is below the en-suite bath & basin outlets then it's negative head. - They are not cheap though so it might be wise to get a plumber to take a look before buying the pump.
