We have just inherited a house. It has a hot water tank and whilst
downstairs is fine the upstairs flow is useless. The bath takes hours
to fill and the shower is almost unusable. Would a shower pump be any
good? There is space and power in the airing cupboard where the hot
tank is. I'll get somebody to put it in but what power should the pump
be? The house is a fairly standard 3/4 bed terrace. By putting in a
pump would it solve the problem? Any suggestions as to which type if I
am going down the right road?

Many thanks
