Hi, I'm hoping to get some ideas from some experts as our Central heating engineer seems perplexed. We have permanent hot water. We have an old Baxi 51/3RS boiler and just at the moment the only way to stop it heating water is to turn off the pilot. The timer is set to off for heating and water. If you turn it on it will flame up and turn if off and it does seem to flame down. The boiler can be set to anything on the dial (including off) and it will heat water. We seem to have no central heating (we turn it on and no radiators get hot even with it turned up). So far the engineer has replaced the actuator on the 3 way valve and as the water was getting very hot changed the thermostat (the water now heats up to 60C and seems to stay there). There was talk of replacing the motorized valve itself but i'm not sure he is convinced it is that as you can hear it operating (making a cogs are moving noise) when the timer tells it to (Could it be stuck open and still make the noise). Anyone got any ideas ? Mike.
get another "heating engineer",ideal one who knows what he's dealing with,there's not a lot that can cause those problems.
concur with phil, get someone in who knows what eze doing, should be a basic thing with probs the zone valve as thats what fires up the boiler!
