I've decided I'd like a vaillant boiler and narrowed the choice down to ecotec plus 837 or ecotec exclusive 838. Seems like there is only £60 between the two, is it worth getting the exclusive? Do the extra bits actually mean much?
I started looking at the control options and liked the look of the VRC 430. It looks like it's all the controls in one box, so I'd mount it where I'd normally mount a thermostat, is that right? That is bang in the middle of the house. There must be an external thermometer wire, is there any particular place that should be located? Any idea what length of cables come in the box for thermometer and connection to boiler?
