What actually happens if you leave the immersion on

Oh god oh god oh god.

Have you ever caught yourself wondering if you left the immersion on? Of course you have.

Nothing tests the nerves of the nation like the immersion.

We asked an expert if we’re all daft or if there’s actually consequences to leaving the immersion on.

Dublin’s Immersion Heater repairs and fits immersions all over Ireland (they must be fierce busy).

They shared the following wisdom with us.

“The main problem with leaving an immersion on constantly is that the immersion thermostat will be constantly switching on and off. After so many hours the thermostat will give up, causing one of two problems.”

“Problem one is that the immersion will not work. At all.

“Problem two is that the immersion will stay on causing the water in the immersion cylinder to boil. When the water boils the cylinder will make loud noises and push the boiling water into the cold tank in the attic. The water coming out of the cold tap will also be boiling.”

So, there you have it folks. Leave it on = scalding yourself or breaking the thing.

Never forget.
