Water main booster pumps

[mitchellplumber]

I have just installed an unvented hot water system in a 5 bedroom house with 5 showers. The cold main is only 1 bar from the mains. Does anybody know if a booster pump can be fitted with a pressure vessel without the need for a breaker tank? And if so, Can You recommend one?

Cheers

pretty sure you will need a break tank to comply with water regs

You can only 'pull in' what's available and connecting booster pumps directly to the main can actually cause backflow from other properties mains supplies when in operation. Anything pumping over 12 litres per minute needs permission from water company!! As Steve said, probably have to have a break tank, lots of 'packages' available from manufacturers but quite expensive or what about an accumulator?

Was the pressure/flow up to it before you installed?

No, its a new build house. Out in the sticks, but it is mains water. Just not very great half way up a very large hill :0(

Bummer. Perhaps a 'normal' cylinder with a pump might have been more cost effective.
