Quantum is the world’s most advanced, Lot 20 compliant and SAP accredited high heat retention storage heater.
The pure white casing and anodised aluminium grilles create a clean and stylish look which complements any environment; a perfect upgrade for older, static storage heaters.
Now with upgraded iQ controls, the Quantum Series G.6 retains rotary dial operation and adds more intelligent software functions than ever, saving you money and giving you increased control over your heating comfort.
At the heart of Quantum is the intelligent automatic charge control. This algorithm learns your usage, lifestyle and climate conditions and adapts accordingly, using only the required amount of low cost, off-peak electricity needed to charge the unit to meet your heating requirements. This ensures that no energy or money is wasted, so you can relax and enjoy your perfect room temperature – all without lifting a finger.
By using primarily off-peak energy, it is predicted that 90% of the heating requirement will be met with low cost energy, offering you savings of up to 27% compared to a standard storage heater system** and up to 47% compared to an electric convector or radiator system**.
Quantum now has 3 customisable heating timers, each with four time and temperature settings for each day of the week. You can also temporarily adjust the heat levels manually with the user-friendly rotary control if you prefer, to give instant heat when you need it - day and night.
The newly added ‘Boost’ function provides a more specific temporary boost of heat outside of timed heating periods, in addition to the existing ‘Advance’ function. An improved ‘Away’ mode allows for a return time and/or date to be set, allowing the heater to maintain a lower background temperature in your absence to avoid mould or damp, before returning to regular timed operation upon your return. Other features of the new Quantum Series G.6 include PIN-code locking with customisable rulesets, per-heating mode peak-rate/stored energy control, ‘setback’ temperatures, frost protection, charge control offsets and more!
For the first time, Quantum can now be remotely controlled via the internet using the Dimplex Control smartphone app*. With Dimplex Control, you have total control of your supported Dimplex products, anytime, anywhere. The app allows you to control and configure your heaters or hot water cylinders, individually or by zone, and easily track the energy usage of each.
Quantum is the product of over 70 years of heating experience, from our own in-house research, development, design and manufacturing facilities in the UK. Unlike most electric heaters, Quantum is BEAB Approved – the highest safety standard achievable in the UK. This means you can enjoy a wonderfully warm home and sleep soundly knowing Quantum is designed to be extremely reliable and maintenance free. However, for additional peace of mind, we also offer a FREE 10-year guarantee*** with additional online registration.
Switching to Quantum gives you complete control over your home heating, providing adaptability and affordability with its unique storage heating technology.
