For over 60 years. Dimplex has built its portfolio to the point where it is now the brand leader in electric space heating, offering over 700 products, the widest in the world. Its growth can be attributed to providing affordable heating solutions that are efficient, reliable and durable, as well as attractively designed.

The UK Heating market is changing at a very fast pace. Rising CO2 Emissions and spiralling fuel costs mean find a more energy-efficient way to heat our home is our main priority.

Features of The Quantum Heater


Great advances in insulation technology and controllability ensure the Quantum heater is up to 27% cheaper to run and uses up to 22% less energy than other comparable electric heaters.

The Quantum heater uses insulation material which comes close to the lowest theoretically possible thermal conductivity – an insulation with a thermal conductivity even lower than that of still air.

Better still, Quantum uses off-peak tariffs whenever possible to minimise costs, so users can enjoy all the benefits of electric heating, with running costs unattainable by other direct acting electric systems. And to top it all, the Quantum heater is easy to install and virtually maintenance free.
