I wonder if anyone can help me? We have a direct water heating system system with an electric immersion heater and a back boiler (coal fire). I would like to disconnect the back boiler because it's rubbish and its pipework is in the way.
I plan to:
1. Drain the hot tank & boiler.
2. At the tank, disconnect and seal off the 2 connections to the boiler - is this OK or should I link them together instead?
3. At the boiler, cut the pipes close to the wall but leave the ends open to allow warm air to escape when the fire is in use - I presume this would be safer than sealing it up? I don't want to remove the boiler as this would involve hacking into the chimney.
Any help would be much appreciated.
I've had a look through the project section but I can't find anything specific to my query.
I don't have any problems with draining the system, disconnecting and rerouting pipework etc., I just want to know whether it's safe to leave our old back boiler in situ without any plumbing going to it. It's just on a coal fire but I don't really want it to go bang...
