I've just discovered today that the new house I've moved into has no thermostat connected to the boiler. There is a thermostat on the wall in the living room, but it isn't connected and don't know where the wires are. The British Gas engineer advised getting a Wireless thermostat fitted by an electrician. Would this work? Does the Worcester 24i allow a wireless thermostat to be fitted. The current space where the thermostat should connect to the boiler is empty.
