My wife and I are just refurbishing our flat and are putting in a new system. Water pressure is very low as on top floor so tank only 1m above maximum. Also mains incoming only 15mm and runs through 4 flats below first. We had a vented system before and ran a shower pump for the shower. We'd really like to have better pressure throughout to be able to use good fittings. Space can be made for a larger tank as necessary. Any suggestions on the best way forward would be really helpful!
New hot water heating for 2 bed top floor flat

Put a 50 gallon cistern in the loft, and run everything except WC cisterns and kitchen cold tap off a twin impeller pump fed from that.
This assumes that you have a conventional vented heating system. If not then let us know what you do have.

Thanks for the good advice Softus. We actually have nothing there at all at the moment so we could put in whatever works best. It would be nice not to need a pump as they do make a racket if you get up in the night and need to wash your hands. High pressure systems seem difficult to install and I'm not sure what boiler type we would require etc.
Your solution seems like the one we'll follow, as we're on site already and need to make decisions quickly. Any suggestions on a quiet twin impellor pump would be a great help - as would a pumpless solution. Thanks again.

Put as big a cold water cistern as you can and fit a 3 or 4 bar pump as Softus wrote. You'll need to size the hot water cylinder accordingly. Think of using an unvented one that gets around many problems and allows you to put the pump out of the way by the cold water tank.
It'll also giv eyou the option of removing the cws and pumps at a later date is the mains supply improves.
You'll need a G3 qualified installer.
A decent system boiler is all you'll need probaby 18kW would be sufficient although it would depend on your flat.
Stewart Turner every time for pumps - they are the K9's globes.
Pumpless option would be an accumulator but I doubt that would be practicle - what is your water pressure (not flow!)? Simon here likes them (email will coming your way soon I promise).
