Replacing an Old Central Heating Timer
4 Answers
My elderley parents central heating sytsem dates back to the late 1970's. It's a Baxi Bermuda W2 Fire/Back Boiler. It has been regularly serviced and stilll works ok - but the actual Central Heater timer is faulty. It is a Switchmaster 400. It has a dial style timer knob, where you pull out lugs to set the on/off times, and two switches, one for Timed/Constant, and one for Water/Heating & Water.
In a nutshell, the dial no longer works - it does not go round, hence the central heating/water is either on or off using the constant option. There is no room thermostat fitted (wish there was), and no way of setting how hot the hot water temperature reaches.
Is it possible to replace this very old Timer, keeping the original fire/boiler, and if so can you suggest any suitable ones. I appreciate that this may not be a DIY job, so I would happily call in a plumber/heating contractor, but would line an idea of what is possible, and ideally how much it might cost. Many thanks
