JG Speedfit underfloor heating issue

by Dickdutch » Thu Dec 15, 2022 5:16 pm

I’ve got JG speedily underfloor heating downstairs with rad heating upstairs, it’s been working fine until recently, upstairs is fine, but the underfloor isn’t working.

The thermostats are all connected, but it’s not triggering the boiler, as soon as I switch the boiler on for the heating upstairs, heat circulates underfloor.
Any ideas?

Hi dickdutch,
Suggest you investigate the zone valve for the UFH and make sure it is operating correctly.
Regards S
