    ufh keeps blowing the programmable thermostat capacitor

    We have a Worcester boiler with UFH downstairs and CH upstairs. The CH and DHW run off a Delta Dore Tybox 827 WRF programmable thermostat (all working fine) whilst the UFH off a Tybox 337 programmable thermostat. Both wired into a standard wiring centre. The 337 keeps "blowing" and failing to...

    Nope - original pump, valve, everything - although whole system is only c18 months old

    Two zone weather comp heating possible??

    So would an EcoTEC Plus boiler, VRC430, VR61 and VR81 allow me to control DHW / UFH / Rads separately? Would I need anything else? The cylinder is an unvented Gledhill

    Two zone weather comp heating possible??

    okay thanks again. Sorry to be a pain. I'll stop suggesting solutions as I'm not an engineer, but instead just what I want to achieve... How do I achieve a constant 19 degree temperature in every room of the house (UFH down, rads up) with max efficiency (i.e. weather comp) and minimal...

    Two zone weather comp heating possible??

    Thanks Tony. Your comment about controlling both UFH and rads from the boiler with simple weather comp... Sounds perfect... can two room thermostats be fitted to that? i.e. one in UFH and one upstairs? If so that will do the job perfect. Any recommendations on boiler / controls...

    Two zone weather comp heating possible??

    Hi I hope someone can help - am a homeowner not an engineer! We have new UFH downstairs and rads upstairs. I'd like one UFH zone, one rad zone and DHW. All separate and all independent. One thermostat in UFH, one upstairs for rads. Heating weather compensated. We have a Gledhill...

    Dual Zone + weather compensation - possible?!?

    Thanks guys, all great. I've looked at the FW100 from WB and as far as I can see (not an engineer!) it doesn't permit dual Zone UFH & rads?

    Dual Zone + weather compensation - possible?!?

    So a Vaillant VRC 470 would be perfect... not expensive...but not compatible with a WB boiler... Surely someone (Honeywell?) must do something that works?
