Electric Storage Heaters
Electric storage heaters are insulated units that store heat during off-peak times to help decrease your energy bills. They store the heat and release it as you need allowing you to enjoy the comfort of a well-heated home at the off-peak price.
Off-peak times are when demand for electricity is low and is usually set on an Economy 7 meter between 12pm – 7am each night.
Your dual meter will record the amount of electricity you use during normal hours and off-peak hours and you are billed accordingly. As a rule of thumb, off-peak charges are roughly 1/3rd of peak rates, so there are substantial savings to be made. The heaters are extremely well insulated and have much better controls that older versions

How Do Electric Storage Heaters Work?
New storage heaters have smart controls allowing the unit to store and release heat based on previous usage and room temperature. The thermostat within the electric storage heater allows the system to know the room temperature and calculate the heat it needs to warm it to the temperature you would like.
With the electric storage heater, you’re still in control; you decide what temperature you would like the room to stay at and the system works to ensure the room stays comfortable. Electric storage units are usually wall mounted, looking very much like a conventional radiator.
Benefits of an Electric Storage Heater:
- Lower energy bills
- Free 12-month maintenance contract
- Low installation cost
- Quick installation process
- Reduced carbon (CO2) emissions
- Enhanced durability
Installing Your Electric Heating System
Electric storage heaters are usually wall mounted meaning they usually do not require redecoration or any planning for installation.
Installation processFrequently Asked Questions
Lorem IpsumElectric storage heaters contain high-density ceramic or clay bricks. Inside the unit, electric heating elements warm these bricks up overnight (usually during "off-peak" hours when electricity is cheaper). The bricks are highly effective at retaining thermal energy, allowing them to release heat gradually throughout the following day.
Because they are designed to store energy rather than provide instant heat, they typically take 6 to 8 hours to fully "charge." This usually happens overnight. However, modern "High Heat Retention" (HHR) models are better insulated, meaning they heat up efficiently during your off-peak window and hold that heat much longer than older models.
Dimensions vary depending on the power output (kW) required for the room, but typical sizes are: Width: Usually ranges from 50cm to 100cm. Height: Typically around 70cm to 75cm. Depth: Usually between 15cm and 20cm. Note: Larger rooms require more bricks to store more heat, which results in a wider unit.
No. You can mix and match your heating system based on how you use each room. Many homeowners use storage heaters in "high-traffic" areas like the living room or hallway to provide a constant base temperature. In rooms used less often, such as spare bedrooms or bathrooms, you might choose standard electric heaters or towel rails that can be turned on and off instantly as needed.
