Immersion Heaters

Do old immersion heaters use more energy than new ones.

Electric Ireland: Brige N

Hi patricio,

Thanks for getting in touch.

Old appliances may be less energy efficient than newer appliances.

The usage of an appliance, or a heater, is determined by the number of units used by the appliance. The basic unit of electricity is the Kilowatt hour (kWh). In simple terms, 1 kWh is the amount of energy used by a 1kW (1000 watt) electric heater for one hour. Another example is ten 100-watt light bulbs used for one hour would equal one unit.

The number of units used should then be multiplied by your unit price (which can be found on the reverse side of an Electric Ireland bill), this will provide you with the cost per hour of the appliance.

Further information on this can be found here.

Customers can also view the average cost of running various appliances through the Electric Ireland My Energy Pal web app, available here.

Should you have any questions please let us know.

Thanks,
Brige

Thank you.

Hi patricio,

Thanks for your message.

The energy efficiency of appliances improves over time, due to developments in the technology associated with the various appliances.

We would be unable to discuss the efficiency of a specific appliance. However, when purchasing appliances look for the energy rating label, try to go for those with an 'A' rating as these are the most efficient.

For further tips on how to make your home more energy efficient, we would recommend visiting the Electric Ireland website here.

Please let us know if you have any further queries.

Thanks,
Brige

New immersion heaters are a bit better insulated hence more energy efficient. I'm not sure how old you mean but I saw really old ones with insulation being literally torn into pieces..

Hi All, Just visiting my parents house over the weekend and noticed the hot water is way too hot. My parents heat water using an immersion heater so I automatically thought I could turn down thermostat. On opening the top of the immersion I can't see an obvious thermostat, it's a Stanford dual star K71 .... best part of 20 years old fitted to top of standard copper cylinder. Is it likely this immersion predates ones which have thermostat fitted or am I missing something.
Thanks for your advice

Hi Sean, 

Thank you for getting in touch. 

Here in the Social Media department we look mostly after billing or Sales queries. 

We are unable to advise in relation to this. We recommend consulting with an electrician or the manufacturer. 

Please let us know if there is anything we can assist you with.

Thanks,
