Dimplex Quantum QM125

Quantum is the worlds most advanced storage heater. It uses low-cost, off-peak energy, making it the most economical electric heating system on the market today. Plus, it adapts to match lifestyle and climate conditions, delivering heat only when it's needed. With its compact, state-of-the-art design, Quantum is the perfect upgrade for static storage heaters and suits a wide range of applications.

Dimplex Storage Heater features

  • Cost savings - Quantum is up to 27% cheaper to run than a standard storage heater system. It's also up to 47% cheaper to run than an electric convector or radiator system.
  • Heat on demand - Quantum stores energy up during periods of low demand, turning it into efficient heat only when needed. Through its use of a sophisticated self-learning algorithm, the IQ controller can take just the right amount of heat to match the users lifestyle and changing weather, intuitively and precisely.
  • Total control - Quantum QM125 is fitted with the iQ controller so you can pre-set your heating requirements, just like central heating. Manual adjustment, if required, is also simple with its easy-to-read LCD display and user-friendly low torque rotary knob, designed with the visually impaired in mind.
  • Peace of mind - Quantum comes with a 2-year warranty and is also BEAB approved.
