Storage Heaters

We are asked this question often and the answer depends on budget and individual requirements.

Our best selling storage heater is the Dimplex Quantum. With advanced weather-based controls and smart home compatibility, it's the perfect choice for efficient and affordable heating.

For upgrading older storage heaters like the Dimplex XLS or Creda TSR is the Elnur PROSSH is the top choice, featuring smart off-peak heating and flexible programming with control via LCD display, app or smart speaker.

The Dimplex XLE is the perfect budget-friendly storage heater. It features energy-efficient functions such as open window detection and adaptive start, comes in multiple sizes and boasts a stylish appearance.

For maximum energy efficiency, opt for Elnur HHR Solar Storage Heaters or Elnur Smart Solar Storage Heaters. These innovative models prioritise solar power, drawing from the grid only when necessary. The integrated IEM ensures optimal charging based on weather conditions and your daily needs.

Storage heaters harness the power of off-peak electricity, typically available at night. This cheaper night time electricity charges internal ceramic or other heat-retaining energy cells which release heat during the day. Many models feature advanced controls like thermostats and smart technology for enhanced efficiency and personalised heat management.

Modern HHR models are indeed cheaper than standard electric heaters and can be cost-effective on off-peak tariffs. Recent data (e.g., Ofgem/price cap as of early 2026) shows average electricity at ~27-28p/kWh, with off-peak often 15-20p/kWh or lower on some tariffs. A typical 2kW heater charging fully overnight might cost around £2 per day in off-peak use. By utilising off-peak tariffs and incorporating various energy-saving features, modern storage heaters are significantly cheaper to run than standard electric heaters or central heating systems. You can reduce costs further by using solar panels with storage heaters that are solar compatible. With minimal maintenance and a long lifespan, storage heaters provide a cost-effective and sustainable heating solution.

The diagram below illustrates how to work out how much a storage heater costs to run per day:

Check with your energy supplier to find out the difference in cost between on and off peak and discover how much you could save!

*Actual running costs for individual rooms will vary according to insulation levels, weather conditions, sizing of heater, and required room temperature.

Storage heaters are typically programmed to turn on at specific times and temperatures, as set by the user through dials or digital controls. Since January 1st, 2018 all new storage heaters in Europe are required to adhere to Lot20, regulations, which mandate intelligent, smart control features for enhanced energy efficiency.

These new features include:

- Digital 7-day 24-hour programmable controls for more efficient running
- Open window or door detection sensors to minimise wasted energy
- Adaptive start technology enabling a storage heater to learn and maximise efficiency when warming up a room

Standard storage heater controls include holiday mode and frost protection. For specific user instructions for the storage heaters we sell, look under the specification tab in the product description box. We also have an in-depth guide which includes videos on how to set up a Dimplex Quantum heater.

Smart storage heaters have the ability to be controlled remotely via WiFi at any time from anywhere in the world by smartphone or tablet. A central hub connects the individual heaters to home WIFI via a radio frequency signal which then allows the heaters to be remotely accessed and controlled. Apps such as Dimplex Control provide users with greater control over their heating wherever they may be and provide data feedback on energy usage which is ideal if you are looking for ways to save money on your energy bills.

Whilst gas heating systems are the cheapest to run, the cost of installing or maintaining a gas heating system is often prohibitive.

Storage heaters are ideal if:

- There is no gas supply to your home.
- You do not want the hassle and expense of having a gas boiler and central heating system installed or maintained.
- You live in a rental property.
- You need to heat a conservatory or room extension.
- Your home has solar panels, which can generate the electricity to heat the heaters.

Rule of thumb for storage heater sizing:

Calculate the size of the room in cubic feet by multiplying its height, width, and length together. For example, if a room is 8 feet high x 12 feet wide x 15 feet long, this would be 1,440 cubic feet.

For storage heaters, we recommend 4 - 5 watts per cubic foot.

Example: To heat a room which is 1,440 cubic feet, you would require between 5,760 watts (5.76kW) and 7,200 watts (7.2kW).

To heat 1,440 cubic feet, an appliance like the Dimplex Quantum QM150 which outputs 2kW would be needed.

If you’d like to skip the manual maths, try our Heating Calculator to automatically estimate the required kilowatt (kW) output for your room based on size, insulation and temperature.

Most storage heaters are wall-mounted and supplied with a fixing kit.

Fitting is easy, just follow these steps:

1. Decide where to position your heater and mark on the wall where to drill the holes for the brackets.
2. Fit the wall brackets using the screws provided. Be sure to use the correct screws for your wall type (for example, brick, plasterboard, etc.).

NOTE: Storage heaters are heavy, so make sure your wall can hold the weight.

3. Hang the heater onto the wall brackets, and using a screwdriver, lock the heater to the brackets.
4. Always use a qualified electrician to wire your heater to the mains. Standard storage heaters must be installed by a professional electrician.

The most popular storage heaters on the market (including our best seller, the Dimplex Quantum) are all ‘Dual Supply’. This means they require a permanent live connection and an off-peak connection.

If you are replacing older storage heaters (such as Dimplex XL or Creda TSRE) you will likely find that these heaters are Single Supply, meaning they run from a single power source.

The Elnur ECOSSH is the only storage heater on the market that can run from a single supply, making it ideal to retrofit without the need for costly rewiring.

Rewiring for a dual supply storage heater is not a DIY job; a qualified electrician must do it to ensure correct wiring to a two-tariff meter and a separate off-peak (Economy 7) circuit.

Yes, modern storage heaters are designed with eco-friendly features that help reduce your carbon footprint. Many models incorporate Lot20 features and advanced technologies that optimise energy usage, such as programmable timers and adaptive start features, ensuring that the heater only uses energy when it’s truly needed.  Storage heaters are 100% efficient at point of use and some models can be paired with solar PV for less reliance on the grid and further lowering carbon footprint. By taking advantage of off-peak electricity rates, these heaters contribute to a more sustainable home by using renewable energy sources efficiently.

High heat retention storage heaters are designed to store heat for longer periods, ensuring that the heat generated during off-peak hours is released slowly throughout the day. This advanced technology helps to reduce energy consumption by maximising the use of cheaper off-peak electricity, allowing your home to stay warm without the need for additional heating throughout the day. These heaters are ideal for households looking to reduce energy costs while maintaining consistent comfort.

Yes – and it's one of the smartest ways to maximise your solar investment. If you have solar PV panels installed (or are planning to), solar-compatible storage heaters allow you to store surplus daytime solar energy as heat in the heater's core, rather than exporting it back to the grid at low feed-in rates. This boosts your self-consumption, reduces reliance on expensive peak-rate grid electricity and can significantly cut your heating bills while lowering your carbon footprint.

Elnur Gabarron HHR Solar Storage Heaters are designed specifically for solar integration. They feature advanced insulation for longer heat retention, fan-assisted output for even distribution and compatibility with solar PV to store surplus as usable heat. These heaters ensure optimal charging from solar first, then grid if needed. 

Elnur Gabarron Smart Solar Storage Heaters add smart app control (when used with G-Control Hub). You can monitor solar usage, adjust settings remotely and even integrate voice control (Alexa/Google). They support solar diversion and provide detailed energy stats to track savings.

Yes – smart models make it easy to manage whole-home or zoned heating from one place. Control multiple heaters remotely via app (scheduling, temperature adjustments, energy tracking), group them into zones (e.g., living areas vs. bedrooms) and monitor usage to optimise savings.
