25 years-old Glow Worm 24cl needs replacing, but no-one will take on the job, because of difficult/impossible access to the outdoor vent pipe.
Since the boiler's original installation in the first floor flat's kitchen, a conservatory roof has been erected below, in such a position that no ladder can be positioned for the work.
I have had the heat exchanger flushed, an expansion tank fitted and the filling loop replaced, but still the hot water runs - literally - hot and cold, a very unpleasant showering experience.
It occured to me that if the 24cl is still in production, or it is possible to buy a completely reconditioned unit, it might be possible to unplug/disconnect the old one and slot into the same mounting position, a complete as-new replacement, using the same vent-to-exterior and overflow drip pipes as before.
I am aware that there will have been numerous regulations over the decades, but I am hopeful that some solution on these lines might be do-able - or if not, any suggestions from a thoughtful professional would be gratefully received.
