Hi,
I have a Johnson & Starley Hi Spec M31 System ET. I have had to drain the water heater as I have replaced a leaking hot water cylinder. The problem is that I do not know how to refill the heat exchanger/water heater and have no hot water! The only access point seems to be the drain tap. Can anybody help?
(PS There is a small radiator/towel rail on the same system in my bathroom.)
