Storage heaters are a popular option for those looking to heat their homes efficiently, especially in areas where other heating options are limited. They are designed to make use of off-peak electricity, storing heat during the night and releasing it during the day.
But what does it actually cost to run storage heaters, and is it a good option for your budget and energy needs? This article dives into the costs, factors affecting these costs, and tips for maximising the efficiency of storage heaters.
Introduction to storage heaters
Storage heaters are electrical heating devices that store thermal energy during off-peak hours and release it when needed. This type of heater is common in areas with off-peak electricity pricing plans, such as Economy 7 and Economy 10 in the UK, making it attractive for households aiming to reduce heating costs.
Given the rising focus on energy efficiency and sustainability, storage heaters can be a practical choice—but understanding the costs is essential to making the right decision.
How storage heaters work
Storage heaters operate by using electricity to heat ceramic or clay bricks within the heater overnight, typically during low-cost, off-peak hours. These bricks retain the heat for several hours, which is then gradually released throughout the day.
Some models allow users to control when heat is released, which enhances efficiency and comfort. This approach allows homeowners to benefit from cheaper energy rates while still enjoying a warm home during the day.

Types of storage heaters
Storage heaters come in different types, each with unique features that can impact operating costs. Understanding the options available can help homeowners choose the best type for their needs.
Standard storage heaters
Standard storage heaters are the most basic model. They store heat during off-peak times and release it gradually. However, they lack advanced controls for managing heat output, which can result in heat loss when not needed.
These heaters are often less expensive upfront but may cost more in energy usage.
High heat retention storage heaters
High-heat retention storage heaters come with improved insulation, which allows them to store heat more efficiently and release it when needed.
They often include controls for adjusting heat release and retaining warmth longer, making them a better option for energy savings.
Combination storage heaters
Combination storage heaters, also known as “integrated storage heaters,” offer the benefits of standard storage heaters while incorporating an on-demand heating element.
This extra feature provides supplementary heat during peak hours if required, offering more flexibility for users who may need a boost of heat outside of regular off-peak times.
Factors that affect the cost of running storage heaters
The cost of running storage heaters is influenced by several variables, which homeowners should consider to maximise savings.
Electricity tariffs
The primary factor in storage heater costs is the electricity tariff. Off-peak tariffs, like Economy 7 and Economy 10, offer lower rates during specific hours, allowing users to heat their storage heaters at a reduced cost.
However, without these tariffs, costs can increase significantly, as peak electricity rates are much higher.
Size and insulation of the space
The size and insulation of the room or home impact how much energy is required to heat it. Well-insulated spaces retain heat longer, reducing the demand for the storage heater.
Larger, poorly insulated areas will demand more energy, leading to higher operating costs.
Usage patterns and time settings
Using storage heaters effectively involves setting the heater to charge during off-peak hours and adjusting the release controls based on daily needs.
Households with irregular schedules may find it challenging to rely solely on storage heaters without incurring additional costs from peak-hour heating.
Understanding electricity tariffs for storage heaters
In many areas, energy providers offer specific tariffs tailored for storage heater use, designed to encourage energy consumption during off-peak hours.
Standard tariffs vs. economy 7 and economy 10
- Standard Tariffs: With standard tariffs, electricity costs remain consistent throughout the day, leading to higher costs for storage heater users, as they cannot take advantage of off-peak rates.
- Economy 7: Economy 7 tariffs provide seven hours of off-peak electricity at a lower rate, generally overnight. This plan is beneficial for storage heaters, as users can heat their units during these hours at a lower cost.
- Economy 10: Economy 10 offers a ten-hour off-peak period spread across day and night hours, providing more flexibility but often at a slightly higher rate than Economy 7. This tariff suits users needing heating both day and night without resorting to peak-hour electricity.
Average costs of running storage heaters
Estimating the cost of running storage heaters involves calculating both fixed and variable expenses, which vary depending on the type of heater, local electricity rates, and personal usage habits.
Cost breakdown by heater type
- Standard Storage Heaters: These typically cost around £8 to £12 per month if operated solely during off-peak hours.
- High Heat Retention Heaters: With better insulation and control options, they can reduce monthly costs to £7 to £10.
- Combination Heaters: Combination heaters can cost upwards of £15 per month if supplementary peak-time heating is required.
Average costs per month and year
On average, households can expect to spend between £300 and £600 annually to operate storage heaters. For smaller homes with efficient insulation and regular off-peak usage, costs may be on the lower end.
Larger homes or those with poor insulation may reach the higher end of this range.
Comparing storage heaters with other heating options
Storage heaters are one option among various heating solutions. Here’s how they compare with other common methods.
Storage heaters vs. gs central heating
Gas central heating typically costs less than electric heating options, but installation requires a gas connection and boiler.
Storage heaters may be more expensive per kWh, yet they offer flexibility in locations without gas lines or where off-peak tariffs are available.
Storage heaters vs. electric radiators
Electric radiators provide on-demand heat, giving users control over heating each room. However, they lack the cost-saving advantages of off-peak usage, making them more costly to run if used frequently.
Cost-saving tips for running storage heaters
Making the most of storage heaters involves optimising settings and enhancing home efficiency.
Optimising heat settings
- Set your heater to charge only during off-peak hours.
- Adjust the output control based on weather and home occupancy.
- Lower settings when rooms are unused to conserve stored heat.
Enhancing home insulation
Good insulation helps retain the heat released by storage heaters, reducing the need for extra heating. Simple improvements, like installing draught excluders, upgrading window insulation, and adding thick curtains, can all contribute to energy savings.
Pros and cons of storage heaters
