Dimplex Quantum QM125RF HHR storage heater has the world’s most advanced controls and settings, providing efficiency above all other brands on the market. This smart heater uses the Dimplex Control App to control and configure multiple heaters individually or by zone, as well as monitor your energy usage, providing a smart solution to your home or work place electric heating. To connect to the App, the heaters require one Dimplex Hub (purchased separately) per property, this will connect to all the compatible dimplex heaters over Wifi and allow you to control your heating from anywhere in the world - no more wasted energy when you're away from home! This App-controlled storage heater also has a user-friendly rotary control that allows you to manually adjust your heating.

The new Dimplex Quantum RF Series boasts an array of new and improved features, including three customisable heating controls (each with four time and temperature settings for every day of the week), and an away mode that runs the heater steadily at a lower temperature until you get back to avoid mould and damp. However, the main draw of Quantum storage heaters is their (newly upgraded) iQ controller and it’s intelligent automatic charge control calculation. This algorithm takes into account your average usage, lifestyle, and even climate conditions, to work out the optimal amount of energy needed to reach your temperature at your desired time, ensuring no money or energy is wasted.

Dimplex Quantum storage heaters are 27% cheaper to run than standard storage heaters, and 47% cheaper than other electric heating systems, such as convectors and radiators. They are also EcoDesign Lot 20 compliant, with adaptive start and open window sensing technology. To make the most of these features, these electric storage heaters should be used in conjunction with an Economy 7 electricity tariff.

SAP accredited and BEAB approved, Quantum RFs and designed with safety and reliability in mind. They also come with a free 10 year guarantee (after online registration, terms and conditions apply).

Sadly, inherited storage heaters in my 16th century property and, as putting in gas central heating isn't an option at the moment, have replaced all the old heaters with Quantums.
Apart from looking much better than the old ones, they are so much more efficient and far more functional.
Would definitely buy again.

I replaced some 15 year old Dimplex storage heaters with these new quantum heaters - they have completely changed the home environment - now nice and warm when I want it and the biggest benefit is they're using about 15% less electricity - I would have been happy with just being warm...
