Heating that’s cool
for the planet

With Quantum in your home, you can reduce your carbon emissions.

How? It’s all thanks to the intelligent charging tech inside every heater. When there’s high demand for electricity on the grid, Quantum can pause charging, preventing the need for carbon-heavy gas-powered generators to be switched on.

By charging up later on when the grid is more likely to be powered by renewables, your heaters can help to fight global warming as part of a more flexible grid.

Heating by the experts

The Quantum range is built on 70 years of heating experience – designed and manufactured by Dimplex right here in the UK.

Designed to Europe’s highest product safety standard (BEAB) and built for reliability, you can sleep soundly in a warmer, safer home.

Don’t just take our word for it. With a 10-year limited warranty 3 when you register the product with Dimplex, you know you’re investing in a name you can trust.
