I live in a three bed house with my partner. It's a three storey
property with a toilet on the ground floor and a bathroom on the first
floor and radiators throughout. We've inherited an old central heating
system which consists of a gas boiler, hot water cylinder and header
Next year we're looking to rip out and redo the entire ground floor of
our house. As part of this project we plan to get rid of the existing
heating system (the boiler is on the ground floor), and replace it
with a combi boiler. I've read the combi boiler FAQ on this site and
am happy with the compromises this brings.
My main concern is that of pressure/flow. Currently our cold tap in
the kitchen doesn't have very strong flow. It's OK (a plumber did
measure the flow and thought it was OK), but not fast flowing. We want
ensure that we have a really good shower (on the first floor) and are
concerned that there's won't be anough mains pressure to supply this.
A builder recommended that we use a Megaflo to resolve this, but I'm
not actually sure we have a problem. I checked the mains pipe which
runs from the front of the house and it's 15mm. Could this be
restricting the flow?
How can I find out for sure if the mains pressure will be suffient for
a good shower?
