Removing your storage heaters 

The bad news first: removing storage heaters is not a DIY job, so this is the part of the process that will cost you the most money. However, once the decks are cleared, installing electric radiators is a quick and easy process that your electrician can do as part of the overall project.

Hiring an electrician to remove your storage heaters

If you don’t know much about storage heaters, you may be disappointed to discover that removing them is not just a matter of disconnecting the heaters from the wall. That’s because storage heaters always come hardwired, so it’s never as simple as just whipping out the plug! Storage heaters are hardwired because they need special wiring in order to work with a two-tariff meter.

What to expect

Your storage heaters will be connected to the mains via two electric circuits: one which carries off-peak electricity, and another that carries on-peak electricity. This allows your electricity meter to record how much electricity you have used at different times of the day. Your energy supplier can then calculate how much energy to charge at the lower rate, and how much at the higher. When you have your storage heaters removed, your electrician will need to:

  • Remove or rewire off-peak circuits
  • Convert storage heater sockets to ordinary sockets
  • Earth and install circuit breakers where necessary
  • Test, certificate and write report

For one storage heater, this should take 1-2 hours. For an entire houseful of heaters, the process might take 1-2 days. Depending on where you live, the state of your existing wiring and the level of certification required.

You can expect it to cost you anywhere between £500 and £1000 to have an entire houseful of storage heaters removed.

What to consider

When looking for an electrician to do the job, you should consider the size of the task. It may work out cheaper to pay a lump sum if you just have a few storage heaters to remove. If you have an entire houseful of heaters to shift It’s likely more economical to choose an electrician who charges by the hour. To help your electrician work as efficiently as possible, make sure all rooms are tidy and your heaters are easily accessible before they arrive.

How to dispose of your storage heaters

Tool kit

Some electricians will include the disposal of your storage heaters within their fee. Others may offer to organise disposal as an optional extra. However, disposing of your storage heaters yourself can be an easy way to save money.

Dismantling your storage heaters

Storage heaters are very heavy – essentially, they’re metal boxes full of bricks, and can weigh anything from 40kg to 400kg. Luckily, they can be dismantled once removed: use a screwdriver to open up the metal casing and take out the heating bricks one by one. However, you should not attempt this if the storage heaters have been used for heating within the last week – the bricks are designed to retain heat and won’t be safe to remove until they’re cold.

Methods of disposal

Once you’re in a position to move your storage heaters, you have three main options for disposal:

  1. Take to the tip – This method is not recommended if you are getting rid of multiple heaters because of petrol costs and the potential damage to your car posed by the heavy bricks.
  2. Hire a skip – Skips are available in a range of sizes and allow you to dispose of a large amount of waste quickly and easily, with no risk of damaging your vehicle.
  3. Give them away – You could make use of community recycling sites such as Freecycle or advertise the bricks to local farmers/builders who can put them to use as hardcore for farm tracks or pit-filling.

Asbestos in storage heaters

If your storage heaters were installed before 1974, they may contain asbestos insulation. The Asbestos Information Centre have published a list of historical storage heater models which are known to contain asbestos. We recommend checking your storage heaters against this list before hiring an electrician. If there is any chance at all your storage heaters contain asbestos, you should consult an expert before removing.

Coming off Economy 7

Before installing electric radiators, you will need to switch from your Economy 7 tariff to a standard electricity tariff. This is essential: electric radiators use electricity as-and-when they produce heat. If you remain on Economy 7, you will be charged the inflated daytime electricity rate whenever you use your radiators – a sure-fire way to rack up a hefty electricity bill. Switching to a standard electricity tariff will allow you to make the most of energy efficient electric heating.

How to change your tariff

To change your energy tariff, you’ll need to phone your supplier and have a new electricity meter fitted. Most suppliers will do this for free. Don’t be afraid to shop around – the UK has a wide range of tariffs on offer, so it’s always worth comparing the market to find the best for you.
