Hi, my name is XXXXX XXXXX I have been in the home improvement and repair field for 20 years. I will be glad to help you today. Are the radiators cooler on top and warmer on the bottom? Do you have a combi system?
I have an E combo system
Do you know what your system pressure is at?
It is 1 and a half
How about the radiators themselves? Are they cooler on top and warmer on the bottom? Is the problem with all of the radiators? Hot water works fine?
They are completely cold, all of them. Hot water is fine.
Did this just happen or did it happen when changing the settings? Do you have a wireless thermostat?
Yes I have a wireless thermostat. This happened during the course of the day . I manually change the temperature settings as I go along. It could have happened during one such change.
The wireless thermostat is still connected? When was the last time the batteries were changed?
Yes it is still connected. batteries were changed more than 8 months ago.
Is the pump really hot? Humming?
No pump is not humming and it is not hot.
It is running though?
Yes, I think so
The issue would be with the diverter or port valve. Likely the port valve is sticking. If you remove the diverter and can free the port valve that may be all it needs but if the port valve has been sticking it may have burnt out the diverter and the diverter would need to be replaced.
Even when the boiler is only 14 months old?
Is the diverter and port valve also new?
Yes everything is new.
This is a new home? The whole piping system was replaced?
Yes it s a refurbished home the her is new piping.
I'm going to opt out. Something doesn't add up there and I don't know what it is.
Do I get a refund?
You won't even let me rate this. It's off to the regulator then
How do I rate when the expert has opted out?
No rating needed. Another expert should take over soon.
