Heat storage stones to suit the HWAM 5530 modular woodburning stove.
Heat storage is a phenomenon known from the large mass stoves where heat is stored in the stones surrounding the combustion chamber.
Heat storage in a wood-burning stove is the combination of the wood-burning stove’s ability to quickly and comfortably distribute the convection heat and the mass stove’s ability to store the heat.
The compartment can be filled with a large amount of stone. Stone has a special ability to store heat from the wood-burning stove, which will then slowly be emitted into the room, even long after the fire has died.
While the wood-burning stove is burning, the stone in the heat storage compartment will be heated up. Once the fire in the combustion chamber has died, the stone will continue emitting the stored heat into the room.
Tests show that stone in the small heat storage compartment will keep warm for up to 10 hours, whereas stone in the large storage compartment will keep warm for up to 14 hours after the last stoking.
The models HWAM 3130, HWAM 3520, HWAM 3650, HWAM 3660, HWAM 3760, HWAM 4150, HWAM 4160, HWAM 4550, HWAM 4560, HWAM 4660, HWAM 5530 and HWAM 7150 are constructed with a heat storage compartment for the heat storage.
As an extra feature, HWAM 3520, HWAM 3650, HWAM 3660 and HWAM 7150 have a knob which regulates the convection air to the heat storage compartment. When the convection damper is closed, the heat stored in the stone will be retained in the heat storage compartment for as long as possible; once the damper is opened, the heat will be distributed to the room as quickly as possible.
A wood-burning stove with HWAM® Autopilot ™ ensures excellent combustion – for the benefit of the environment and your firewood consumption – without any manual regulation of the air supply.
Thanks to a bimetal spring, the air supply to the combustion chamber is automatically adjusted to get the most heat out of your firewood. The bimetal spring expands or contracts, depending on the temperature of the combustion chamber, thereby regulating the dampers so that the fire is supplied with the right amount of air.
All HWAM stoves are equipped with HWAM® Autopilot ™ as standard.
