Storage heaters are electric heating systems that store heat during off-peak hours and release it when required, meaning you’re paying for cheaper (overnight, off peak) energy.

It employs convection currents to distribute heat throughout the space. As the heat rises, the hot air from the heater draws in cooler air. As a result, this heat is regulated by the heater. The cycle continues, distributing heat evenly throughout the space.

How do storage heaters function?

Storage heaters store affordable electricity-generated heat during the night and release it during the day. They use electricity to heat ceramic or clay bricks overnight and progressively release the heat to keep your home warm the following day.

Night storage heaters are mainly designed for households with time-of-use electricity rates, such as Economy 7. These have cheaper electricity rates overnight (approximately midnight to dawn, but times can differ).

This allows you to heat your home during the day using less expensive off-peak electricity.

 

How much do storage heaters cost?

The price of storage heaters in the UK can alter depending on several factors, including the heaters type, size, brand, and additional features.

Standard storage heaters cost between £300 and £600 per unit, excluding installation fees. Advanced variations with enhanced features, such as digital controls or increased energy efficiency, may be priced at £600 to £1,200 or higher.

Advantages of storage heaters

  • Energy efficiency: The energy efficiency of storage heaters is one of their greatest benefits. These heaters utilise nighttime off-peak electricity to charge thermal blocks or core elements, releasing heat during the day.
  • Cost-effective: Storage heaters are renowned for their affordability. They can significantly reduce your monthly heating costs.
  • Even heat distribution: Unlike alternative heating methods, storage heaters provide consistent and even heat distribution. They progressively release stored heat throughout the day, keeping your homes temperature comfortable and stable.
  • No gas required: Storage heaters operate solely on electricity, making them a viable option for households without a gas connection. 
  • Low maintenance: Storage heaters are recognised for their minimal maintenance requirements. Unlike boilers and other heating systems, which may require routine maintenance, storage heaters require minimal upkeep. 

Disadvantages

  • Limited temperature control: Storage heaters release heat gradually throughout the day, dependent on their charge from the previous evening. This means that you have limited real-time control over altering the temperature. 
  • Ineffectiveness in mild weather: Storage heaters are most effective in regions with distinct day-to-night temperature differences. These heaters may not be as effective in milder climates or seasons with a smaller temperature difference between day and night.
  • Bulkiness and aesthetics: Storage heaters can be more cumbersome and less aesthetically appealing than other heating options.
  • Limited portability: Once installed, storage heaters cannot be moved or relocated without difficulty. 

How to maximise the use of storage heaters 

New regulations require modern storage heaters to include casings to retain more heat or fans to help distribute warm air throughout the room when necessary. In addition, they have more advanced controls, such as:

  • A thermostat allows you to regulate the room’s temperature continuously.
  • Smart charging is used to store the optimal amount of heat.
  • Others connect to your WiFi network and can be managed from your mobile device.
  • Some storage heaters can detect room temperature changes and automatically adjust the heat output.

Storage heater features

The features on storage heaters are listed below for your benefit:

  • Thermal bricks: A storage heaters thermal bricks or core are its main component. These high-density bricks are made from materials with exceptional heat retention properties, such as clay or ceramics.
  • Timing and temperature regulators: Modern storage heaters feature user-friendly temperature and time controls. This allows you to set the operating time and temperature of your appliance.
  • Automatic payment: The sensors within storage heaters monitor the outdoor temperature and modify the charging times accordingly. When it is colder, the heater will charge for extended periods to ensure that there is sufficient stored heat to maintain a comfortable indoor temperature.
  • Mechanical ventilation: Effective and secure operation of storage heaters depends on adequate ventilation. They typically include a grille or vent at the top to vent surplus heat and ensure adequate airflow.
  • Ventilated heat distribution: Some advanced storage heaters are equipped with a fan that helps distribute the stored heat more uniformly throughout your room.

Summary

In conclusion, storage heaters are a cost-effective and convenient method of heating that combines practicality and efficiency. These devices provide warmth while minimising energy consumption via a variety of features.

With their thermal blocks, precise controls, safety features, and eco-friendly operation, storage heaters are a cost-effective option for homeowners seeking to maintain a comfortable living environment.

Storage heaters can provide a sensible balance of comfort and savings, whether you are seeking a sustainable heating solution or trying to manage your household budget better.
