Hi all
I wanna upgrade my Existing Boiler Potterton 70l, my system is 9 years old and has 13 Radiators and has an Unvented Cylinder, also wanna relocate Boiler into Garage which is just a few feet down from where it is now.
Whats the best A rated Boiler to go for also can i move the pump away from the unvented cylinder as well.
Does the Engineer that does this have to be passed on Unvented cylinders or will just normal Corgi be ok
