Understanding Storage Heater Running Costs
When considering whether storage heaters are expensive to run, the primary factor isn't the heater itself, but how and when you use the electricity it consumes. Modern electric storage heaters, especially models like the Dimplex Quantum range, are designed to be efficient by charging up overnight when electricity prices are significantly lower. This off-peak charging is typically facilitated by an Economy 7 tariff or a similar time-of-use electricity plan.
If you are on an Economy 7 storage heater tariff, you benefit from a period of cheaper electricity, often for seven hours overnight. Your storage heater draws power during these cheaper hours, storing the heat in its core for use throughout the day. This makes them an affordable option for many households in the UK, provided the heat output matches your daily needs. The expense arises if your home requires more heat than the stored energy can provide during the day, forcing you to top up with expensive daytime electricity, or if you are not on an advantageous off-peak tariff.
- Charged overnight on cheaper tariffs, they can be economical.
- Daytime electricity use significantly increases running costs.
- Efficient models minimise heat loss for better value.
- Tariff choice is the biggest cost driver.
The Impact of Your Electricity Tariff
Your electricity bill is the main indicator of whether storage heaters are expensive to run. Standard electricity tariffs charge a single rate, regardless of the time of day. Using storage heaters on such a tariff would indeed make them one of the most expensive ways to heat a home, as you'd be paying a premium rate for all the electricity they consume, day and night. This is why they are almost exclusively paired with dual-rate meters and specific off-peak tariffs, such as Economy 7, which offer substantial savings during the designated off-peak period.
Dimplex Quantum storage heaters, for example, are intelligent systems that learn your heating patterns and optimise charging to make the most of cheaper electricity rates, while also minimising energy waste. However, even the smartest heater will struggle to be cost-effective if its primary energy source during peak hours is prohibitively expensive.
Maximising Efficiency and Affordability
So, how can you ensure your storage heaters aren't proving more expensive than they need to be? It boils down to smart usage and understanding your system's capabilities. Modern electric storage heaters uk-wide are generally designed with better insulation than older models, reducing heat loss and ensuring the energy stored overnight is available when you need it.
Proper insulation and draught-proofing of your home are crucial, as they help retain the heat generated by your storage heaters, meaning you require less energy overall. If your house is poorly insulated, the stored heat will escape quickly, leading to a colder home and a greater need to recharge, thus increasing your running costs.
The true cost of storage heaters hinges on leveraging off-peak electricity rates to their fullest.
When to Check Your Usage
If you find yourself consistently needing to boost your heating during the day or if your home remains cold despite the heaters being charged, it's time to investigate. This could mean your thermostat settings are too low, your heater's capacity is insufficient for the room size, or your insulation needs improvement. For those considering upgrading, Dimplex Quantum storage heaters represent a step forward in intelligent heating, capable of automatically adjusting to usage patterns and external conditions to provide heat efficiently.
Ensure your timer settings align precisely with your actual daily needs; avoid over-charging if you don't require a full day's heat, and check that your thermostat is accurately reflecting room temperature to prevent unnecessary energy draw.
Comparing Storage Heaters to Alternatives
The question of whether storage heaters are expensive to run often leads to comparisons with other heating systems. When running on an Economy 7 tariff, electric storage heaters can be cheaper than direct-acting electric heaters (like fan heaters or convection heaters) that consume electricity at the standard, higher daytime rate. However, compared to central heating systems powered by natural gas, they can be more expensive, especially if gas prices are low.
The key benefit of electric storage heaters, particularly for homes without access to mains gas, is their relatively low installation cost and the ability to heat specific rooms without the need for extensive pipework. The decision often hinges on your specific circumstances: the availability of off-peak electricity tariffs, the local cost of gas, and your home's insulation levels. For many, especially those on Economy 7 storage heater plans, they offer a manageable and controllable heating solution that avoids the larger capital outlay of other systems, making their running costs acceptable within a broader budget.
