I have been advised to have a Vaillant Ecotec Plus 937. Should i make sure the Vaillant VRC 400 weather compensator is fitted at the same time?
The boiler will be in the center of the house, so not near an outside wall, so will that make it difficult to fit the outside sensor? i guess it could go to the roof where the flu will go but that is 4 meters away vertically.
Finally please can someone explain exactly what the weather compensator does.
Thanks,
Rob
