Why is my boiler not firing up? | Boiler Plan

There are a number of reasons why your boiler may not be firing up, with many of them straightforward enough to resolve on your own. 1. Thermostat Setting. If the room's temperature is higher than the thermostat setting, then your central heating won't start up. Check the thermostat and increase the temperature if necessary.
