Hi, I have a problem with a drip appearing to come from the joint between to two parts of the heat exchanger on my 55/3. It doesn't leak when cold with pump running. It drips after boiler fired up for about 5 mins - about 1 drip every 30 seconds or so. After about 20 mins the drip stops and doesn't return whilst the boiler is running. Question: should I a) attempt to re-gasket the joint between the two halves; b) replace the heat exchanger with a new one; or c) put up with it as it is? Option d is not favourite (replace boiler ££££); I note a wide price range quoted on internet for replacement. Around £300 from MJT, £145 from Boilerpart.com. Any comments?
Many thanks
