Resolving Intermittent Shutdown Problems in Your Home Heating System.

When it is very cold outside and it is snowing or freezing, it is nice to know that your home boiler can keep your family warm and safe..

What happens if your boiler keeps turning off before your home has warmed up enough?

There are reasons this happens. Here are five possible causes of shutdown problems in your boiler.

Thermostat Problems

One reason your boiler may shut off unexpectedly is a problem with the thermostat. The thermostat may be instructing your boiler to turn off. You should check one thing.

Is your thermostat set to heating mode or automatic mode?

Is the fan set to on or automatic mode?

Try adjusting the thermostat to at least five degrees higher than the current room temperature.

You should also check your programmed temperature settings. You may have set a temperature reduction that causes your boiler to turn off.

Running Out of Heating Oil

If you have not refilled your heating oil tank since winter, you may have run out of fuel. This can cause your boiler to shut off unexpectedly. You should check your tank gauge. The tank gauge is like a car fuel gauge. It has a floating disk that shows how much fuel is in your tank. If the disk is at the bottom or you cannot see it, your tank is empty. You need to get fuel.

Low Water Pressure

Your boiler needs a certain amount of pressure to operate properly. Over time the pressure can drop. This can happen when radiators are bled or there is a leak. If pressure drops too low, your boiler may shut off. Display an error code. To fix this, you should check for leaks. Repressurise the system. You can find instructions in your boiler manual. Some boilers are easy to top up yourself. If you need to open panels or use tools, it is best to call a licensed technician.

Boiler Short Cycling Problems

If your boiler keeps turning on and off continuously, this is called short cycling. This helps prevent overheating. It wastes energy and puts extra strain on your boiler system. The problem may be that your boiler is too large. It can also be due to pump issues, restricted pipework, or poor system design. You can contact the Cubby team for help with your heating system.
