How Much Does a Storage Heater Cost to Run?
One of the first questions homeowners ask before replacing their heating system is “How much does a storage heater cost to run?”
The answer depends on several factors, including the age of your storage heater, the type of electricity tariff you use, the insulation in your home and how your heating is programmed.
Modern storage heaters have improved significantly over the last decade. Today’s high heat retention storage heaters are designed to make better use of off-peak electricity while providing greater comfort and improved control compared with older manual models.

What Affects Running Costs?
What Affects Storage Heater Running Costs?
There isn’t one simple answer because every home is different.

Older Storage Heaters
Do Older Storage Heaters Cost More to Run?
Many homes throughout Dublin still have storage heaters that were installed 20 or even 30 years ago.
Although these heaters still provide heat, they generally have:
- Manual controls
- Older insulation
- Greater heat loss
- Less accurate temperature control
- No intelligent charging
Many homeowners also find them difficult to programme correctly, which can lead to wasted stored heat and reduced comfort.

Modern High Heat Retention
Better Control of Stored Heat
Modern storage heaters have been designed to improve the way stored heat is managed throughout the day.
- Better insulation
- Improved heat retention
- Digital controls
- Electronic thermostats
- Intelligent charging
- More consistent room temperatures
Rather than allowing stored heat to escape continuously, modern heaters release warmth when it is required, helping you get better value from your Night Saver electricity.
Night Saver Electricity
Night Saver Electricity and Storage Heater Running Costs
Storage heaters are designed to charge overnight using lower-cost electricity supplied during Night Saver hours.
The stored heat is then used throughout the following day.
Using the correct tariff is one of the most important factors in keeping running costs under control.
If your storage heaters are connected incorrectly or your Night Saver system is not operating properly, your heating costs can increase significantly.
The Key Point
Charge at the Right Time
A storage heater can only make proper use of off-peak electricity when the tariff, timer and electrical supply are working as intended.
Common Reasons Heating Bills Increase
Why Have My Storage Heater Running Costs Increased?
If you’ve noticed higher electricity bills, the cause isn’t always the storage heater itself.
A professional inspection can often identify the cause quickly.
- Incorrect heater settings
- Faulty thermostats
- Damaged heating elements
- Poor insulation
- Windows or doors allowing heat to escape
- Incorrect timer settings
- Charging during daytime electricity instead of Night Saver hours

Modern insulation reduces unnecessary heat escaping from the casing.
Easier Programming
Digital controls make it easier to match heating to your daily routine.
