High heat retention storage heaters
What are high heat retention storage heaters?
High heat retention storage heaters are an electric heating system designed to store heat and release it gradually throughout the day. They use electricity to heat internal ceramic or clay blocks during off peak hours, usually overnight when electricity can be cheaper.
The stored heat is then released slowly to warm your home during the day. Modern high heat retention storage heaters are far more advanced than older storage heaters. They include improved insulation, digital controls and fans that allow the heat to be released when it is needed. This helps maintain a comfortable temperature while making better use of electricity.
How they work
High heat retention storage heaters charge up overnight using electricity. Inside the unit, dense heat retaining blocks store the heat generated during this charging period
During the day, the heater gradually releases the stored warmth into the room. Modern models use sensors, timers and thermostats to control when heat is released, helping match heating with when the home is occupied. Some systems also include small fans that push warm air into the room when required. This makes heating more controllable and efficient than traditional storage heaters.

Are high heat retention storage heaters right for your home?
High heat retention storage heaters can be suitable for flats, and for properties where it isn’t possible to install central heating. They work better in well-insulated homes. Modern systems offer improved control compared with older storage heaters. However, they cannot provide hot water and are unlikely to be an improvement if you currently have central heating. Heat pumps are a better low-carbon option for most homes.
Main benefits of high heat retention storage heaters
High heat retention storage heaters can offer several benefits for homes that rely on electric heating. Modern systems provide improved control, steady warmth and better efficiency compared with older models. Below are some of the key benefits to consider.
Reliable electric heating
High heat retention storage heaters provide dependable electric heating for homes without central heating. By storing heat overnight and releasing it gradually during the day, they help maintain comfortable indoor temperatures while using electricity more efficiently.
Use off peak electricity
Storage heaters typically charge overnight using off peak electricity tariffs when energy can be cheaper. By storing heat during these lower cost periods and releasing it later, households can make better use of electricity and potentially manage heating costs more effectively.
Government grants & incentives
Modern high heat retention storage heaters include digital controls, timers and thermostats. These features allow households to adjust heating schedules and release warmth when it is needed, helping improve comfort compared with older storage heater systems.
Easy to Install
Storage heaters aren’t part of a central heating system, so they don’t come with any pipework. They simply need to be mounted on to the wall and connected to the electricity supply by a qualified electrician.
Steady, consistent warmth
Because heat is stored and released gradually throughout the day, storage heaters can provide steady warmth rather than short bursts of heat. This can help create a more consistent indoor temperature and a comfortable living environment.
Lower carbon than some heating
When powered by electricity from an increasingly low carbon grid, high heat retention storage heaters can produce fewer emissions than some traditional fossil fuel heating systems such as oil or coal, helping support cleaner home heating.
What you need to be aware of
Storage heaters rely on electricity and can be expensive to run without suitable tariffs.
- They work best in well insulated homes that retain heat.
- Heat is stored overnight, so planning heating use is important.
- Units are larger than some other electric heaters.
Storage heaters only provide space heating, so you will need a separate system for hot water.
It’s also important to consider if heat pumps are suitable for you and your home first. Heat pumps are about three times as efficient as storage heaters, so are a better option for most households.
What to expect during installation
Installing high heat retention storage heaters is usually straightforward, especially when replacing older storage heaters. An installer will remove existing heaters if needed and connect the new units to the electrical system. Installation may also include setting up controls or timers. Work is typically completed within a day depending on the number of heaters being installed.
Running & maintenance
High heat retention storage heaters are designed to operate with minimal maintenance. Once installed, they charge overnight and release stored heat automatically during the day. Occasional checks of controls and settings may help ensure they are operating efficiently and providing the right level of warmth.

High heat retention storage heaters FAQs
Yes, storage heaters can be suitable for many older homes, particularly those where it would be impractical to install central heating. Homes with good insulation will usually benefit most, as this helps retain the heat released throughout the day.
Yes. High heat retention storage heaters include improved insulation, digital controls and better heat management compared with older models. This allows households to release heat more effectively and maintain a comfortable temperature.
Storage heaters charge overnight but release heat during the day. Modern systems allow you to control when the stored heat is released, helping match heating with when the home is occupied.
Storage heaters should be used with off peak electricity tariffs that offer cheaper electricity overnight. This allows the system to store heat at lower cost and release it during the day.
Running costs depend on electricity prices, insulation levels and how the system is used. In well insulated homes and with suitable tariffs, modern storage heaters can provide effective electric heating.
Before installation, your installer may check the electrical supply and identify suitable locations for the heaters. You may be asked to clear space around existing units or walls where the new heaters will be installed.
