We are currently having plenty of work done on a house and we are considering a Vaillant EcoTEC 937 but before we take the plunge we'd like to know how much a replacement heat exchanger is likely to cost. We live in a hard water area and had to replace one on our old Vaillant TurboMax (which wasn't too expensive).
We currently have a water softener installed in the house and basically want to work out if it's worth keeping it...
Any rough idea gratefully received...
