A high heat retention storage heater is an electric heater designed to retain heat during off-peak electricity hours and then gently release it over time. This permits the heater to operate at a reduced cost, as off-peak rates are less expensive than peak rates.

Using electricity, the heater heats a big mass, such as ceramic bricks or clay, which may store heat for a lengthy period. The stored heat can be gradually released using a thermostat to manage the room’s temperature.

How can they improve your EPC?

High-temperature storage heaters can substantially enhance the Energy Performance Certificate (EPC) rating of a property by increasing its energy efficiency. These cutting-edge heating systems operate by storing heat during off-peak hours, when electricity is less expensive, and progressively releasing it throughout the day. By utilising this heat storage technology, high-temperature storage heaters are able to reduce your reliance on peak-hour electricity, resulting in reduced energy consumption and carbon emissions.

This increased energy efficiency results in a more favourable EPC rating, indicating that the property is more sustainable and environmentally benign. Moreover, the efficient heat distribution provided by these heaters guarantees a comfortable living environment while minimising energy waste. By installing high-temperature storage heaters in your home, you can not only increase your EPC, but also reduce your energy costs and contribute to a sustainable future.

Energy Performance Certificates

An Energy Performance Certificate (EPC) tells you how energy-efficient a property is. It would be best if you had an EPC  in England and Wales when you’re:

  • selling a property
  • renting out a property
  • building a new property

You must order an EPC for potential buyers and tenants before you market your property to sell or rent.

In Scotland, it is not compulsory to have an EPC rating though there is talk of legislation changing this in the future.

An EPC contains:

  • information about a property’s energy use and typical energy costs
  • steps to improve a property’s energy efficiency and save money

An EPC gives a property an energy efficiency rating from A (best) to G (worst) and is valid for 10 years.

Electric panel heaters are 100 percent efficient, as 1 kilowatt of energy is converted into 1 kilowatt of heat. 

But due to the high energy cost, even a gas boiler with a 69% efficiency rating will score higher on the EPC than a brand-new electric heater. This is because heating the comparable property with peak rate electricity costs approximately four times as much as heating it with gas.

The most frequent error to observe among landlords is the replacement of outdated storage heaters with electric panel heaters.

However, an alternative is replacing the old storage heaters with contemporary heaters with great heat retention. Not only are they sleeker and more contemporary in appearance, but they also store heat more efficiently and positively improve the EPC rating.

The Operation of high heat retention storage heaters

Storage heaters heat a sequence of ceramic bricks or panels with electricity during off-peak hours, generally at night when energy rates are lower. Insulating these bricks or panels prevents heat loss and allows heat to be stored until required. During the day, the stored heat is released into the room via convection and radiation, maintaining a pleasant temperature.

High-heat-retention storage heaters’ advantages

One of the primary advantages of storage heaters with high heat retention is their capacity to keep the heat for extended durations. This means they can continue emitting heat even when the electrical heating element is turned off.

This is especially helpful for households and companies that must keep a constant temperature throughout the day. High-heat-retention storage heaters are a cost-effective solution to heat a space since they allow you to take advantage of decreased electricity prices and cut your energy costs.

They are also a fantastic option for those needing an eco-friendly heating solution, as they can assist in lowering the overall power demand and decrease carbon emissions. Storage heaters with high heat retention are an economical and environmentally beneficial solution for heating homes and workplaces.

They can help cut energy expenditures and carbon emissions by taking advantage of off-peak energy rates and releasing stored heat throughout the day. They can provide a continuous and comfortable source of inexpensive heat if used and maintained properly.
