Storage Heater Safety and Efficiency Guide

Storage heaters are a cost-effective and efficient way to heat your home, especially if you’re using off-peak electricity tariffs. However, like any electrical appliance, they must be used safely and efficiently to prevent accidents and to ensure they operate at their best. Here’s a comprehensive guide on storage heater safety and how to use them efficiently and correctly.


Understanding Storage Heaters

Storage heaters work by storing thermal energy during off-peak hours when electricity is cheaper, typically at night, and releasing the stored heat during the day. They’re particularly beneficial for those on specific electricity tariffs that offer lower rates during off-peak times.

Safety Precautions


Professional Installation

Always have your storage heater installed by a qualified electrician. Incorrect installation can lead to safety hazards such as electrical fires or electric shock.




Ensure there’s adequate clearance around the storage heater. Keep all combustible materials, such as curtains, furniture, and clothing, at least one metre away to prevent fire risks.


Storage heaters should be securely mounted to avoid tipping over, which could cause injury or block the heat distribution.



Regular Checks

Regularly inspect your storage heater for any signs of wear and tear. Look out for damaged cables, loose connections, or anything unusual.

Dust and Debris

Keep the heater clean and free from dust and debris, which can accumulate over time and potentially cause overheating.

Efficient and Correct Usage

Maximising Efficiency

Understanding Controls

Familiarise yourself with the heater’s controls. Most storage heaters have an input and output control. The input controls how much heat is stored, and the output controls how much heat is released.

Optimal Settings

For maximum efficiency, set the input according to your next day’s heating needs. If you expect a cold day, increase the input setting at night. Conversely, if a milder day is forecasted, you can reduce the input setting.

Use Output Control Wisely

Minimise the output during the early hours of the morning if you don’t need the heat, and adjust it according to your needs throughout the day.


Using Storage Heaters Correctly

Take Advantage of Off-Peak Rates

To benefit from lower electricity rates, ensure your storage heater is set to charge during off-peak hours. This typically means setting it to heat up overnight.

Avoid Overloading

Do not place clothes or other items on top of the heater to dry. This can block the heat distribution and pose a fire risk.

Thermostatic Controls

If your storage heater is equipped with thermostatic controls, use them to maintain a comfortable and consistent temperature, preventing overheating and energy waste.


Seasonal Adjustments

Summer Settings

During warmer months, you may not need as much heat. Adjust the input settings accordingly to save energy and prevent unnecessary heat accumulation in your home.


Safety with Children and Pets


Always supervise children and pets around storage heaters. The surface can become very hot and may cause burns upon direct contact.

By following these guidelines, you can ensure your storage heater operates safely and efficiently, providing comfortable warmth to your home while optimising energy use and costs.

Regular maintenance and proper usage are key to maximising the benefits of your storage heater and ensuring it serves you well for many years.
