The central heating in my house has evolved over the years; there is a 22mm backbone to the boiler with 15mm and 10mm branches. It is an open vented system and at a guess several radiators have been added onto the branches over time.
There must be a limit to the heat supply capability of 15 and 10mm pipe, can anybody help me with some rough indication as to what the limits are? Obviously it is no good having the boiler big enough if it cant get the heat through to all the radiators because they predominantly hang off a 15mm pipe.
