Hi, just had to have a new boiler fitted by Alde because the previous owner of my Burstner had the system filled with an incorrect mixture of antifreeze which had corroded some of the seals. So Alde removed and tested these parts from my boiler. I am now attempting to recover some of my costs. The control display is the newest version and only six months old. All items are £75 each plus p&p... save a fortune .. Kind Regards Pete
