I have a problem with my central heating the house is 6years old and
was built by Barratt's and the heating installed by Butco.
The boiler is a Potterton Suprima the hot water is stored in an IMI
Flowmax thermal storage and combination unit.
The problem we have is that we have very poor hot water performance
even with the boiler running there is not enough to fill a bath the
shower only stays warm and the temperature fluctuates when a tap is
run. The boiler sometimes does not fire up and the central heating
pump does not run when heating is called for this is over come by
re-lighting the boiler.The heating seem's to run okay and with the
stat set on 30 the system is soon up to temperature.
Any help gratefully recieved
Most problems relating to heating will stem from Boiler and Electrical. Main
step is to look at boiler ensure electrics are operating any port valves you
may have depending on your system wether it is Y plan or S plan. S= 2 port
Y=3 port valve
This should operate your heating and hot water as you demand valve should open.
