Hope someone will be kind enough to give some advice on this ongoing problem. Though I've done lots of plumbing and a fair bit of heating this has got me stuck.
Ideal Mexico HE30 (floorstanding) boiler about 3 years old, Grunfos pump 2-3 years old and Honeywell 3port valve 1 year old. Honeywell room stat - new.
Rads throughout (balanced) reach reasonable temp when programmer set for CH but when set for CH and HW the upstairs rads go cold.
I've had all the rads off and flushed with a hose so feel that they should be okay and run de-sludger through for a week. Now wondering if there could be a section of pipework upstairs clogged.
Any suggestions would be most welcome.
