How does the Dimplex Quantum Tariff save me money?

As part of our award winning4 partnership with Dimplex, we’ve designed this tariff to offer low-cost electricity, helping keep your bills down and your home warm comfortable.

This tariff is the first of its kind, all powered by the smart technology in your storage heaters.

  • Dimplex Quantum storage heaters have technology inside them that we can use to communicate with the National Grid.
  • We can make sure your heaters store the energy you need when it’s cheapest, which is usually at night.
  • Your heaters are then able to release the stored heat for when you need it.

It’s better for the environment too:

  • We’ll control your heater charging during the night. That's when pressure on the grid is lower, and we can take advantage of cleaner, renewable electricity.


The Dimplex Quantum tariff is just one of the ways we are rewarding customers for better energy use through our PeakSave initiatives. PeakSave rewards customers for changing how and when they use electricity helping to reduce demand at its busiest.

Don’t have a Dimplex Quantum storage heater?

This is a special-price Economy 7 tariff we can offer to customers who have a Dimplex Quantum storage heating system.

If you have storage heaters installed from a different manufacturer, we can’t offer you this tariff, but you can still get an energy quote and pick from our available tariffs.

How do Dimplex Quantum storage heaters work?

Quantum from Dimplex, is one of the world’s most advanced electric space heaters. Like other smart storage heaters, it stores heat using off-peak electricity. This off-peak electricity is cheaper for you because it’s when there’s less demand on the National Grid. The heater then releases the stored heat for whenever you need it.

The Quantum smart storage heater can adapt to your usage, lifestyle and climate conditions. This means that will only provide heat when it’s required, making sure less energy and money is wasted.

Is it worth upgrading my storage heaters?

If you already have electric storage heaters in your home, but they’re older, you might want to consider upgrading them. New models can hold more heat for longer periods. They also have better insulation to make sure heat is only released when it’s needed (often via a fan-assisted system). Many modern storage heaters also feature a thermostat and timer or programmer. This means you can set heat to be released at the time that suits you.

Newer models are better for control, heat retention and overall efficiency.
