A modest electric storage heater may use around 1kW when charging heat, while larger versions may require closer to 3kW. That’s a lot of electricity, but keep in mind that it’s the maximum amount it’ll need. When they’ve stored enough heat, some storage heaters turn off the power. As a result, this figure should only be used as a guide.
Running costs
The operating cost of a storage heater is more difficult to calculate because it is dependent on how much heat your room requires. To give you an idea, a medium-sized storage heater that uses 2kW and uses full power for seven off-peak hours will use 14 kilowatt-hours (kWh). That’s 1.37 each day at 9.8p per kWh on average.
Seasonal costs
Obviously, heating isn’t required all year. As a result, your storage heater’s operating expenses will be substantially reduced in the spring and autumn, and they may even be non-existent in the summer. In the warmer months, charging the same heater in the preceding example for only two hours will cut the cost down to less than 40p every day.
Is it more cost-effective to have storage heaters on all of the time?
They’re made to function with the Economy 7 system. This is a tariff in which nighttime electricity is significantly cheaper (usually around a third of the price), but daytime electricity is more expensive. The cheapest hours are usually from 12 a.m. to 07 a.m. in the winter and from 01 a.m. to 08 a.m. in the summer, however this varies. More information on Economy 7 can be found here.
Storage heaters offer a straightforward set of controls. The heater’s input setting allows you to choose the amount of heat it stores overnight. This is significant because, despite the low cost of night-rate electricity, there’s no purpose in paying for more than you require. You don’t need to set the input to maximum if it’s not especially chilly or if you’ll be out of the house for the majority of the day because it’s pointless to store so much heat. Because most storage heaters only charge at night, you can leave the input setting alone and avoid paying high day-rate electricity.
There’s also an output option on the controls that lets you decide how much heat the storage heater emits. The faster the heat is discharged into the room, the higher the setting. This means the heater will run out of stored heat if the output is high all day. It is preferable to gradually reduce the output, saving some heat for later in the evening. Set the output to minimum overnight or when you are gone, otherwise the heat you have paid for will be squandered.
A ‘boost’ setting is available on some storage heaters. This does not use ‘cheap-rate’ stored heat, but instead requires expensive daytime electricity when turned on, hence it should be used only after the stored heat has run out.
Even if the controls on your night storage heater differ, they all work on the same input and output concept.
Because the controls for night storage heaters can be a little complicated, we’ve created a short (2 minute) video that explains how to operate them. Your optimum settings may differ from those shown in this video, and may fluctuate from day to day, depending on your needs and circumstances (for example, when you are at home during the day and how much warmth you require).
Is it expensive to run storage heaters in the UK?
Night storage heaters are made to work with an Economy 7 electricity plan. This implies you’ll pay a lower rate for power for seven hours at night (usually between midnight and 7 a.m.), but a higher charge for the rest of the day. Night storage heaters charge up during the off-peak time at night, store the heat, and gradually release it during the day without the use of power.
You may not instruct your heater to charge enough at night if you don’t grasp what the settings operate, resulting in you running out of heat halfway through the next day. Alternatively, you could let all the heat out too quickly in the morning, leaving you with none later in the day. You could then use the ‘boost’ button or an extra heater to keep warm during the day, both of which will consume expensive premium-rate electricity.
More tips for electric heating
If you have electric heating, Economy 7 can help you save money, but you’ll have to change your way of living. Keep in mind that Economy 7 charges a premium fee for electricity consumed outside of the off-peak time, which is normally roughly 18p per unit. As a result, any electrical equipment you use throughout the day will be quite expensive to run.
If you’re on Economy 7, you should put your water immersion heater on a timer so that it heats your water at night rather than having it on all day. Your hot water tank will stay warm for as long as you need it with a suitable insulating jacket. Other appliances (such as the washing machine and dishwasher) can be run at night to save electricity.

Is it true that space heaters raise your electric bill?
Electric space heaters give instant heat and don’t require any fuel because they run on household electricity. However, you won’t get this level of convenience for free, and if you use one on a regular basis, you’ll see a significant increase in your monthly electricity cost. The cost of running a space heater is determined by its size and frequency of usage, and the cost may surprise you.
Storage heaters
This is dependent on the amount of room you have. If you choose the proper home energy tariff, storage heaters are substantially more energy efficient and might cost less to run. They do, however, take up more room than electric radiators. If you choose a storage heater, you must be considerably more mindful of the home energy tariffs you choose, since prices can quickly escalate.
Switching to an Economy 7 tariff can help you save money on storage heaters. During off-peak hours at night, this tariff gives a lower unit rate for your electricity. As a result, night storage heaters can produce a large amount of heat that can be released consistently during peak daytime hours.
If you choose an Economy 7 plan, it’s critical to get your heating system set up appropriately, as peak unit costs will be greater than on a conventional tariff. If you expend a lot of energy during the day, it might not be the greatest option.
Storage heaters are known for their dependability. They save a lot of energy because they convert electricity to heat with very little waste. One of the most significant disadvantages of storage heaters is the lack of temperature control. You don’t have control over how much heat they produce during the day, so you can’t preserve power for when you need it.
Electric radiators
Electric radiators are frequently confused with electric heaters. As a result, they’ve earned a negative reputation for having excessive operating costs.
Compared to electric heaters, electric radiators are more cost-effective. They utilize all of the electricity they have to heat their home. The biggest advantage is that you can precisely adjust the temperature you choose.
Electric radiators have never been more sensitive as they are now. Turning down your thermostat by one degree can save you up to 10% on your electricity cost, just like turning down your thermostat on your central heating system.
Electric radiators built from recycled materials are available. As a result, they are more environmentally friendly. In comparison to storage heaters, they also produce less condensation. As a result, proper installation is critical, as condensation can cause allergies as well as damage to paint and plaster.
Do storage heaters have a high operating cost?
Is it true that storage heaters are less expensive than central heating? In a word, yeah. They are substantially less expensive to run than traditional electrical heaters since they run on inexpensive night-time tariffs and release energy throughout the day. In addition, they are less expensive to install than a central heating system.
How much does it cost per hour to run a storage heater?
A 2kw high performance storage heater would have a running cost of roughly 13p per hour assuming you only use it on your reduced rate contract.
Why are storage heaters so costly to operate?
Electric storage heaters take advantage of lower electricity rates at night.
Economy 7 tariffs provide homes with a lower nighttime electricity charge. A storage heater, on the other hand, uses electricity to ‘charge up’ with heat at this time. During the day, the heat is released into the house.
Night storage heaters appear to be a smart idea on the surface. However, even with lower night pricing, they are still costly to operate.
Is it cheaper to use an electric heater or a space heater?
Some people purchase or utilize space heaters in the hopes of lowering their energy bills. They are beneficial devices, but they are not appropriate in all situations.
When deciding between space heaters and a central heating system, there are various aspects to consider. One factor is the size of the space that needs to be warmed up.
A space heater may be a better option if you simply need to heat one or two rooms in your home. When compared to central heating, space heaters utilize less energy. They are not, however, as efficient as space heaters. As a result, installing a space heater in each room and putting them all on at the same time will cost you more money, not less.
It’s also important to consider when you bought your heater. Newer models are meant to use less energy than older models. If your central heating system isn’t delivering the same amount of heat as it once did, get it evaluated for any problems or consider replacing it.
How much does an 8-hour run of a 1500-watt heater cost?
That electric heater is doing admirably, but how much will the bill be?
I’ve often wondered how much it costs to run an electric heater. As a result, I conducted research and created a free calculator.
On average, running a 1,500W heater on high costs $0.20 per hour. This works out to $1.60 per hour for 8 hours each day, or $48 per month. The cost of operation is determined by the power of your electric heater, its running time, heat settings, and the cost of energy.
