Hello.
I've an (old) British Gas 330+ Boiler with a cast alloy heat exchanger. It's about to have a 3rd heat exchanger fitted. They've all suffered from blockages due to corrosion products collecting in the exchanger. Am I missing something?
The boiler is downstairs, the pump is upstairs and it is an unpressurised system with a copper tank near the pump. Symptoms are low flow rate, small leaks round the cast iron inlet/outlet unions and the overflow in the loft cycling hot water. I'm using Fernox additive. There aren't new ones about so I've had to buy a Reconditioned one (12 month warranty) with, presumably, some welded repairs round the unions.
Any thoughts?
Ta.
