I always refused to touch it. It was so fragile and the manifold was always somewhere where you couldn't get to it.

On the other hand, we rarely have that radiator turned on, as it's rather pointless. In summer it isn't needed and in winter it wouldn't make much difference, not that we use the conservatory in the winter anyway.

It doesn't matter, though. I don't stick to all the rules!

1. Drain and flush the whole system. Replace rads and defective valves. Refill the system, add a cleaner, run the system as recommended by the manufacturer. Drain, flush and refill the system. Add inhibitor.
2. Exchange radiator(s) add cleaner. Drain and flush - add inhibitor.
Personally, I always prefer No1.

All can now be done from the Hive thermostat, or our mobile phones anywhere with an internet connection.

If no. 1, does that mean you drain and flush twice, or have I misunderstood?
