What happens if your thermostat breaks?

What does a thermostat do on a boiler?
What can a traditional boiler thermostat do? A thermostat maintains the water temperature in your cylinder at a set level. It accomplishes this by heating the water if it falls below the thermostat's set temperature. Then, it shuts off the cylinder's heating to prevent it from becoming excessively hot.
What controls a boiler?
Commercial boilers typically have two or three controls: operating, limit, and sometimes a firing-rate control. Operating control. This device is the principal boiler control and is set at the desired operating pressure or temperature of the boiler. The hydronic boiler operating control is typically set to 180°.
Do you need a new thermostat with a new boiler?
What is changing? Called Boiler Plus, the new regulations mean that, as well as a higher minimum efficiency rating, all new gas and oil boiler installations must include a programme timer and a thermostat so that you can effectively control your heating.
Can you get a thermostat for a combi boiler?

What happens if you don't call for heat from radiators?
If there's no 'call for heat' from the radiators, the boiler stops running, obeying its own temp control. Googler, the temp control on the boiler is a safety feature, and is not to be relied on to contol room temperature. There are a few safety features to help prevent accidents and damage from occuring.
Is the boiler temperature control a safety feature?
Googler, the temp control on the boiler is a safety feature, and is not to be relied on to contol room temperature. There are a few safety features to help prevent accidents and damage from occuring. If one fails it is ok because another will take over. You are using one of your safety features as a control, I believe they are called interlocks. Get a remote room thermostat or a wired thermostat fitted and have one of your TRV's removed where you situate your thermostat. I recommend a Honeywell CM921.
