How do I drain my heating system, which is run by a worcester 350?

There is a drain off point on the boiler however thats not going to drain much of the system. You need to look and see if there are any drain point on you radiators or on the pipe work near the radiators. If your boiler is downstairs and quite low then you could have a drain off on the cenral heating pipe leading to the boiler. Just follow all the downstairs visible pipework good luck

alot of systems do not have drain off points fitted anymore this is bad practice but seems the norm
you can isolate a radiator and drain from valve or nip round to a plumbing supplier a you can now get a drain cock that clamps round existing pipework and you twiste round and it internaly cuts hole in pipework them drain as normal
