What is a storage heater?

Electric Storage Heaters utilise the cheaper off-peak energy available overnight to heat the high heat retention energy cells contained within the unit. The storage heater then utilises the integrated convector heater to release the heat throughout the day in accordance with the desired user-programmed time schedule.

How do storage heats work?

Like other heaters you may browse, electric storage heaters contain a heating element. Heat-retaining bricks often made of ceramic or clay will surround these heating elements within the unit. These materials are used because they’re categorised as high heat retention materials which are perfect for a storage heater.

The heating of the bricks is often done overnight which can be beneficial if you have a dedicated tariff which is cheaper overnight (will talk more about this shortly). These heat-retaining bricks will then hold the heat within a thermally efficient enclosure to prevent losing heat. This is where the name storage heater comes from. The heat is stored until it’s needed for later use in the day.

Most modern storage heaters will have a programmable time schedule which will allow the heat to be released at the right time. This is perfect for early mornings or cold afternoons when you’d like to warm your space but you’re worried about the cost of doing so.

Which electric storage heater is the best?

There are a number of different brands out there designing and creating electric storage heaters, meaning you should shop around and find the best option to suit you. Your needs are going to vary depending on where you’re installing the heater so it’s worth exploring as many options as you can.

You should be looking at the output and whether or not that is suitable for your room. You don’t want to purchase a storage heater that isn’t strong enough to heat your space, but you also shouldn’t purchase one that’s too strong otherwise you’ll be wasting money!

For an office?

If you’re looking for an electric storage heater for your office there are a few things to think about The biggest one is how large your office space is. If your office space is open plan and you’ve got more than 10m2 then you may need to consider looking at a 1500W output storage heater to help cover the entire room.

For a house?

A home is often made up of several smaller rooms that don’t take too much to heat which means that a smaller/less powerful storage heater would be suitable for your rooms. This should save you some money in the long run and make sure that you’re able to heat the entirety of your room easily and efficiently. 

Are electric storage heaters expensive to run?

The running cost of electric storage heaters largely depends on several factors, including the size of the space being heated, the insulation quality of the building, and the specific model of the heater. Modern storage heaters are designed to be more energy efficient than older models, offering better heat retention and more precise control over temperature and timing. This increased efficiency can translate into further reductions in running costs.

Off-peak tariffs

Off-peak energy tariffs in the UK are a practical and economical option for managing electricity consumption during designated low-demand times, commonly in the nighttime and weekend hours. These tariffs are especially beneficial for homes or offices equipped with storage heaters. These heaters are engineered to accumulate and retain thermal energy in periods when energy costs are lower, and then steadily dispense this heat over the day. By syncing with off-peak times, users can achieve notable reductions in their electricity bills, a benefit that becomes particularly pronounced during the colder seasons when heating needs intensify.

Moreover, the use of off-peak tariffs plays a significant role in enhancing energy efficiency and supporting environmental stewardship. By drawing power during times of reduced demand, these tariffs assist in evenly distributing the load on the electricity grid, fostering a more reliable and effective energy provision. This approach is also instrumental in lowering carbon emissions, as power plants can maintain more consistent operation levels. Storage heaters align well with these goals, demanding little upkeep and being simple to operate, ensuring a steady supply of heat all day after being charged in the off-peak window. This synergy of financial and ecological advantages positions off-peak tariffs as an astute choice for users with storage heaters across the UK.

Storage heater installation

It's important to be well-informed about the finer details of installation and the essential UK regulations to ensure everything is correctly executed. Storage heaters are an excellent choice for reducing costs and promoting environmental sustainability, particularly when used alongside off-peak electricity tariffs. However, their installation is more complex than a simple plug-and-play. It is imperative to stay vigilant regarding UK building regulations and ensure that all electrical safety standards are thoroughly met. When installing a storage heater in the UK, consider the following regulations:

  • Building Regulations Compliance: Ensure installation complies with Part P of the Building Regulations, related to electrical safety in homes.
  • Electrical Safety: Adhere to the UK national standard BS 7671 (IET Wiring Regulations).
  • Energy Efficiency: Check if the heater meets energy efficiency standards, particularly in new builds or major renovations.
  • Fire Safety Regulations: Maintain proper clearance around the heater for fire safety.
  • Ventilation Requirements: Ensure adequate ventilation to prevent condensation and dampness.
  • Certified Installation: Use a qualified electrician for installation to ensure compliance and safety.
  • Manufacturer’s Guidelines: Follow the specific installation instructions provided by the heater's manufacturer.

Adhering to these regulations ensures safe, efficient, and compliant installation of storage heaters.
