Inefficient electric heating could be costing you hundreds. Upgrade and save on your energy bills.
If your home relies on electric heating, upgrading to modern storage heaters could dramatically improve your comfort, control, and energy costs.
Whether you live off the gas grid or simply want a more efficient way to heat your home, today’s electric storage heaters offer a safe, low-maintenance solution that works around your lifestyle and electricity tariff.
This page covers how they work, how they compare to older systems, and whether they’re right for your property.
What are electric storage heaters?
Electric storage heaters are designed to charge up during off-peak hours — when electricity is cheaper — and release that heat gradually throughout the day. They're most effective when paired with an Economy 7 or smart tariff, which gives you cheaper electricity during set hours (usually overnight).
Unlike the bulky, basic models from decades past, modern high heat retention storage heaters are smarter, slimmer, and far more efficient. They store heat better, give you more control, and stay warmer for longer.
How do electric storage heaters work?
- Charge overnight when electricity is cheaper
- Store heat using high-density bricks and insulation
- Release heat slowly throughout the day via fan-assisted output or natural convection
- Top up on demand if needed, using standard-rate electricity
They’re ideal for homes without gas — such as flats, rural cottages, or apartments — and for anyone on a flexible or dual-rate electricity tariff.
How do modern storage heaters compare to other electric heating?
Running costs depend on your electricity tariff, home insulation, and heating controls. Well-insulated homes with off-peak or smart tariffs tend to see the biggest savings.
| Feature | Air Source Heat Pump | Gas Boiler | Oil/LPG Boiler |
|---|---|---|---|
| Running Cost (on E7) | Low | High | Moderate to High |
| Heat Retention | Excellent | Poor | Poor to Moderate |
| Flexibility | High | Low | Very Low |
| Installation | Simple | Simple | Pre-Installed |
| Lifespan | 15–20 years | 10-15 years | Varies |
How efficient are electric storage heaters?
While they don’t match the efficiency of a heat pump, modern electric storage heaters are a huge step up from older models.
-
High heat retention: improved insulation keeps heat stored longer
-
Smart controls: some models adapt to your daily routine
-
Zoned heating: heat just the rooms you need
-
Less waste: better control means less energy lost
Compared to traditional panel heaters or fan heaters, storage heaters are far more cost-effective when used correctly.
Are they easy to use?
Yes — one of the main benefits of new storage heaters is ease of use. Features include:
- Digital controls and timers
- Room-by-room settings
- Boost functions for unexpected temperature drops
- Wall-mounted, space-saving designs
Some models also learn your heating habits and adjust automatically, giving you better comfort and savings without constant adjustment.
How much do they cost?
The cost of new electric storage heaters varies depending on brand, size, and how many rooms you’re upgrading. As a rough guide:
- Single-room upgrade: from £800–£1,200
- Whole-home upgrade: from £3,000–£5,000
This includes supply, installation, and full setup.
