I have been experiencing difficulties with my Myson Apollo 50Si boiler recently which are more than a little mysterious. If anyone is able to offer some help, I would be most grateful.
When the system is cold, the boiler starts normally and will run continuously for approximately half an hour, heating all of the radiators to quite a high temperature. It then switches itself off, and will not start until the radiators are cold again. When the boiler switches itself off, it is not possible to switch it on again by turning the thermostat to a higher setting.
