Hello all you helpful people.
I've read though the FAQ's, and ended up a bit confused. I'm starting a thread to collect some opinions. I hope someone will have a little insight into my problem.
- Hot water works fine
- Boiler fires up on CH demand from thermostat, does not lock out
- Pump appears to be running. Switching the pump between I II and III does produce an audible difference.
- Some 'gurgling' apparent at pump/return feed when pumping CH
- Opening the screw in centre of pump: water does flows out. I haven't opened fully or investigated this too deeply, I will do so if I am told exactly what to look for
- Return feed pipe remains cold
- Pressure vessel seems to be properly pressurised, pressure does drop a little bit on CH demand but not to zero
- I can't find any sign of a blockage at the return feed end with a magnet
- System does not appear to be losing pressure over time
Do combi boilers use the same pump to supply hot water? As I'm getting hot water, I'm concerned it may be a blockage. If this is the case, what is my best course of action?
Thanks everyone, help much appreciated. The other half is looking very chilly now the cold weather has set in and I really don't want to let her down
