Thank you all

Blown capacitor identified by Delta Dore after examination back in France. Sorry, no idea which. Will post picture of pump etc and wiring.

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

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

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...

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...

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...

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?

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?

I have UFH being installed downstairs in a new extension / alteration, and rads upstairs. I have a Worcester Bosch 30CDi boiler. Al I want is the ability to control the UFH in one zone, the rads in a second zone (each with own thermostat) and external weather compensation. Seems simple I...

Now have BG man coming round - as you say at least if not fixed I won't be paying. Baffles me how supposed "engineers" (CORGI reg) are so unable to fix a problem but are keen to give you a quote for a new boiler. Difficult to think of many other industries where you still have to pay someone...

Thanks Tony. So what should be done with the tubes etc? Properly taken off & cleaned in water?

cleaned and blown through!

Our 7 yr old Halstead Finest Gold keeps intermittently locking out: - It ignites and fires perfectly every time. - It then tends to lock out ~1-2 mins after ignition. No noise, just a gentle "click" as it locks out. - After two or three maunual resets, when it has warmed up, the problem...
