I have a Vokera compact 25 using an Altech stat. I just bought credit on my gas after running out of gas completely and the radiators and hot water syatem are not working. When the thermostat is set to 21 degrees to demand heating, the boiler shows the green light indicating demand for heating and the thermostat also indicates heating is coming through but still no hot water or radiator heating
