I inherited the above boiler on our new house. All works fine despite looking fairly old. One of the rads wasn't warming up so I bled it but after the hiss of air no water followed. I had a modern boiler in my old house and after you bled the rads you had to refill the system under the boiler. I've read all the instructions but there's nothing telling me how I refill the system. There's also no obvious pressure gauge. There are a couple of Honeywell Motorised Zone Valves located under the boiler. These are all set to auto. Is it possible these control the system pressure?
Sorry if I've completely missed something- not really my forte.
Cheers!
