    Combi boiler conversion

    Personally Id leave the pipework alone, your pressure and flow rate is really good, I cant see any benefit in upsizing, like you say the vaillant takes 15mm inlets anyway! You will need 22mm gas to the boiler, and if it was me Id fit an 837, the 937 is a big boy, dont forget you will need a...

    Honeywell CM907 Room Stat wiring..............?

    Heating controls come under part L of the building regulations, a room stat or trv's are required to comply, having said that the installer only fills in the benchmark form that comes with the boiler, this is a record of commissioning and a record of future servicing, this remains your property...

    heating diagram

    It sounds like a "Y" plan with a zone valve installed for further control, if you want to control both valves you will need a 3 channel programmer like a Horstmann. Just for information I have 2 cylinders in my house standing side by side in the loft, the primarys are connected together and...

    Wiring Honeywell HC60NG

    The receiver would normally be fitted near to the wiring center for ease as you need a permanent live, as at present your live will come via the programmer, this means that when the heating is off on the programmer then there will be no power to the receiver. TS630B Brown = Live Blue =...

    Think carefully before attemping to remove the plate heat exchanger, its not as easy as you might think, If you end up removing the hydraulic block buy some new washers for the primary pipe connections with the white twist fasteners, you also might want to change the PRV at the same time.

    Help with wiring of Room Thermostat - Honeywell T6160

    Gerry, I didnt appreciate you was talking about a combi, your best bet is to look at the connections in the boiler, you should have a "NS" "LS" "LR" "LS" goes to "com" on the Horstmann "LR" goes to "NO" on the Horstmann "NS" = Neurtral, this is not required on the Horstmann Try...
