Hi,
Hoping for some advice! -
A friend of mine was having problems with their central heating - their radiators 'died' one by one and just before the last radiator stopped getting hot, the hot water died too.
The system is conventional, not combi - about 10 years old. The boiler is a Glow worm space saver MK II. Their is a 3 way valve to select hot water, or central heating.
Initially, i thought the problem was the pump, so i changed it but it seems not to be so. The boiler only has a flow and return pipe, along with the gas and it fires up fine. The flow pipe gets HOT and the boiler shuts down presumably due to over temperature. However, upstairs in the airing cupboard the flow to the pump doesn't change in temperature...
Any ideas what this could be - i tried searching the forums but couldn't really find anything.
The pump runs, the motorised valve works and the boiler fires!
I look forward to hearing from anyone who can shed light on a solution.
Many Thanks,
Joel.
