An electric storage heater with a clean look and reliable performance. XLE is a modern replacement for older storage heaters.

XLE storage heaters offer dynamic storage calculation, adjusting the amount of energy that is stored to meet the user’s requirements without wastage. As a result, a greater amount of electricity can be saved with off-peak energy.

Users now have greater control over their heating with the built-in timer, allowing heating times and temperatures to be defined. Heat leakage, a common trait of conventional storage heaters, has also been greatly reduced allowing the room to be at a comfortable temperature in the morning and still have enough stored energy to heat on a night.

Features and benefits:

  • Harness off-peak electricity tariffs for low running costs.
  • Dynamically stores the right amount of energy to heat a room.
  • Fan assisted to quickly, quietly and more effectively distribute heat.
  • Programmable room temperatures with three seven-day timer profiles.
  • Supplied with energy cell packs.
  • Complies with Lot 20 of ERP Directive.
  • CE and BEAB certified.

Two year warranty.
