Hi I am Rick, UK Plumber, and I specialize on Boiler problems,the leak is from the water cooled burner, I think you will find it is beyond economical repair, I have one in my shed that I took out a couple of years ago that was leaking the same, you could try a leak sealing adative, many plumbers swear by it but never worked for me, Rick
Hi Rick, thanks for your reply.
A few questions:
How can you tell the problem is the burner, rather than the heat exchanger please?
I have a friend in the parts business and he can get a brand new burner for the energysaver 40e for approx £50 (his dad owns the firm).
Is it simple to fit and if not, what kind of charge should I expect from a professional?
Below is a picture of the top of the primary(I think) heat exchanger. Are the greenish areas normal, or could they be leaks?
Re: the burner, are the connections marked A and B in the picture below, the only connections to the burner?
Re: Draining the system. Do I go up in loft, switch off supply to tank and then drain system at lowest point (there's a tap in the downstairs hall). Is there a best way to refill?
