Recommend me a water pump

[nads1978]

I'd like to increase the water pressure at my mothers house. It is a bungalow, with a cold tank in the loft, as high as it can be. Pressure would be 0.2-0.3 bar at the taps.
The kitchen has been fitted with a high pressure tap which means warm water is just a dribble (cold is okay, but doesn't have the restriction of the hot water system). Both bathrooms are to be replaced soon, one has a recent pumped cold feed electric shower, the other is an old one that's similar. I intend to instal mixer showers (and obviously, the extra hot water pipework).

There is a Firebird Olympic 50-82 oil boiler, and a hot water tank on ground floor, to consider.

1) What (type of) pump could I put after the cold tank?
2) Would the above benefit from a pressure vessel? (80L?)
3) Would there be an issue increasing water pressure to the boiler?

I'd rather not remove the existing cold tank.

If you are considering a Booster pump, everything downstream will need to be evaluated the biggest requirement would be to replace the hot water cylinder with an Un-vented type (high pressure) this will include expansion provision for the heated water and the temperature and pressure relief valves you should get a qualified person to attend site to carry out a full survey and prepare a specification etc - this is not a project to "muddle" through!

I have one to fit to my vented setup. Adds 0.5 to 0.75 bar.

Thanks, exactly why I asked. Info I hadn't considered!

That is interesting, says it works with an open system. I'll get someone in to assess/do it, but did you get a noticible difference, was yours bad before?

Not fitted it yet; My tank is approx 0.2 meters above the cylinder so my hot water pressure isn't great. (It's aided with old taps which are not 1/4 turn)

I am hoping I will be able to fit a mixer shower with a PEV (Mains cold and pumped hot from cylinder).

Hi, did you get around to fitting it?

Nope. Still on the list of things to do.

Did you fit a pump to sort your issue?

Lol, pressure can't be that bad if it's still not on 12 months later
