Ok
We now have the combi boiler fitted and hooked up to a VRC400. The engineer has sited the VRC400 in the kitchen. Here come the questions!
Am i right in thinking the WC should really be sited in the lounge or back installed in the boiler?
If it is fitted externally (in the lounge)...
We are having a Valliant eco tec plus 831 boiler fitted with a VDC 430 Please could you advise the best internal place for this device to sit?( I appreciate that the outside temp probe has to go on a north facing wall). In the boiler or in a remote room? Presumably we will not need a room...
