Man leaving immersion on for seven years sparks surprising Twitter reaction

A man's supposed disaster of leaving the immersion on for seven years has prompted a rather surprising response on Twitter.

Keith Doyle tweeted:

At first, the reactions were unsurprisingly hilarious with leaving the immersion up there with the worst sins committed in an Irish household. 

Then, people started pointing out that it's not such a bad thing that they have been leaving their immersion on constantly for years. Apparently, plumbers say leaving it on may actually result in a lower bill as the most energy in the system is expended by heating up the water. Keeping hot water hot is more efficient. Who knew!?
