Hwam 3520 4.5kW Wood Burning Stove
The Hwam 3520 is a tall (1260mm) contemporary styled stove with a semi-circular footprint which has a depth of just 371mm. It has two compartments with the top compartment designed to hold an optional 44kg of heat storage stones. For an additional 49kg heat storage the 3520 can also be specified with stone side panel sets, including top, in five different colour variants – Grey Soapstone, Tobacco, Nox Petra or Rosewood Sandstone or San Sebastian Limestone.
The 3520 is Ecodesign Ready, Defra approved and its room-seal has passed the tough German DIBt test, which along with its direct external air supply option, ensures that it is safe to install where there is mechanical ventilation heat recovery (MVHR). The practical 2.0kW to 7kW (nominal 4.5kW) heat output range is controlled and managed with Hwam's Autopilot system with an option to upgrade to the state-of-the-art SmartControl which will improve the stove's efficiency by a further 5.3% as well as save up to 50% on fuel usage.
