Okay... have combi boiler... am draining all system using lowest radiator due to fitting new rad (boiler all off of course). Will fit new rad. Then need to re-fill system and add cleanser.
Question 1: When I refill system with water it's correct to do this with the combi off? Combi off will still allow water to fill system to correct bar (bleeding rads gradually etc.).
Then switch boiler back on...
Question 2: Then run for 1 hour with cleanser at 50 degrees ish (warm). Then drain again. Then fill again but adding Protector. Is this correct?
