THere is no issue with the gas which makes me think the primary heat exchanger is bunged up (the secondary that transfers heat from the boiler to the plumbing is clear).I have a spare but it looks like an awkward job to replace and requires standing on the worktop and messing around near the asbestos in the burning chamber. So, is there a flushing fluid on the market that clears out the pipes before I attempt something more mechanical ?</blockquote>
