Title: Hot water pressure
Post by wozzer on Jun 21^st, 2005, 5:46pm

Suffering with poor hot water pressure in the kitchen (Bathroom shower hot/cold is not that good either) Property is a bungalow, and I can't get the cold tank up any higher, the opper cylinder is as low as it can go.
Questions:
Would you:
a) put in a "whole house" pump?
or
b) go for a mains pressured hot water storage tank system?

Live in a bungalow myself - Megaflow installed when place was new - excellent pressure hot & cold.

Lowering the cylinder wouldn't help anyway - it's the difference between tap and header tank that matters.

I'd check the mains pressure and flow rate and if that's ok go for a presurised system.

Checked the water pressure (ok) but the plumber chappie down the road says that flowrate isn't that good as it is only a 15mm supply pipe.
I ended up getting a Salamander RHP75 which I'm getting ready to fit. The install instructions call for air vents at the highest point of the pipes on the pump outlets (hot and cold) - What type of vent do I fit?

something like those should do the trick.
