It may be time to say goodbye to those long, leisurely morning showers with the electric shower revealed as the appliance that uses the most energy.

The most expensive household appliances to run have been revealed, and the culprit is the electric shower.

The team at Energia, one of Ireland’s leading energy providers, have analysed the 20 most common household appliances in Irish homes, to find out which one is racking up the highest energy usage.

It may be time to say goodbye to those long, leisurely morning showers with the electric shower revealed as the appliance that uses the most energy. Taking a ten-minute shower could cost you up to  €0.59 per day, with a total running cost of €3.39 per hour.

Energy expert at Energia, Claire Love, commented on the analysis: 

“Most of us don’t think twice about taking that extra-long hot shower on a cold morning, but some of our energy habits are costing us.

Aside from the usual suspects of tumble dryers and dishwashers, even using the oven for an hour can add up over time, so looking at ways you can cut that time down is crucial.

Not only can we all be more vigilant with our energy usage, but it’s important we track what's contributing to our consumption by keeping an eye on the energy insights available with a smart plan.”
