Why does my oil burner keep locking out?

A boiler can lock out for several reasons, such as you’ve run out of heating oil, there’s been a power cut, low pressure or a more serious safety issue. Another cause could be an extreme change in boiler pressure, this may occur with a sludge blockage.

The need for this may arise if the furnace becomes too hot, or if there is some sort of electrical system interruption. To get the furnace working again, you simply press the reset button back down again.

Can a boiler explode?

While historically, boilers would over-pressurise and explode with alarming regularity, modern boilers are manufactured to be able to withstand excessive pressure, and can typically handle an operating pressure of 20 PSI. When pressures increase beyond this level, the boiler can fail, which can lead to an explosion.

What happens when a boiler overheats?

If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking. When the water temperature in the boiler becomes too high, it increases the water pressure throughout the system. This will cause breaks to begin occurring at valves and connectors.

How do I reset my Intergas boiler?
