So one problem (now resolved) is the timer ono the boiler had got out of sync and was runinng 3 hours early so in the evenings the boiler shut down too early everything shut down too early.That’s the one to the rads ok the green one is from the boiler so when boosting / turning on this one should run
So fixed that but still the water is luke warm. The system ahs been running for a couple of hours - heating on Hot water on.
In respect of the two pumps
- the pipes into and out of the green one are nice and hot - uncomfortable to hold for more than a second or two.
- the pipes into and out of the red one are much cooler. Warm, almost hot but easy to hold onto for extended periods of time.
Why are hte pipes not hot
OK so the red pump drives the rads? - Its hot but you can hold onto it no problemThat’s the one to the rads ok the green one is from the boiler so when boosting / turning on this one should run
Rads may only be warm 'cos the need bleeding - I'll check
But since the green one is very hot why is there not a tank full of hot water? (Boiler hot water setting has been on for 3 hours) (Both pumps seem to be runing fine)
Sorry - confused
