HWAM Advantages

When you choose a HWAM or WIKING wood-burning stove, you get a stove that helps you achieve optimum combustion. All HWAM and WIKING stoves are equipped with HWAM® Autopilot™ and WIKING® Automatic™, respectively. If you want an electronic and more advanced solution, HWAM® SmartControl™ is available as an additional purchase for most of our HWAM stoves.

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.

In a WIKING wood-burning stove, the regulation of air during lighting and re-stoking is managed automatically through the WIKING® Automatic™ device.

A heat-sensitive bimetallic spring expands or contracts depending on the temperature in the wood-burning stove. When lighting the fire, the damper will be open to ensure that the flames are supplied with the correct amount of air to get the fire started. The following quick rise in temperature will automatically cause the damper to close, thus ensuring clean and efficient combustion. When the fire starts to die out, the damper opens automatically again to allow for new firewood to be added or to let the fire die out.

WIKING® Automatic™ offers many advantages:

• Better comfort
• Easier lighting
• Clean and efficient combustion
• Minor impact on the environment

With HWAM® SmartControl™ you need not worry about how to achieve the optimum and most eco-friendly combustion — the electronic control will take care of this.
Simply download our App “IHS Smart Control” on your phone or tablet. Set the desired room temperature. The app will notify you when it is time to fire to keep the right temperature — without any manual adjustment of the dampers.

To start a fire, you must use the right amount of wood, heat and oxygen. And to achieve the cleanest and most eco-friendly combustion, you need the right combination of wood, oxygen and temperature.

To this end, HWAM® SmartControl has been developed in collaboration with DTU (Danish Technical University). It automatically ensures an optimal combination of oxygen and temperature to achieve clean combustion. The correct amount of oxygen is very important for optimal combustion. HWAM® SmartControl™ constantly measures oxygen levels at the outlet of the wood-burning stove and continuously adjusts the vents to ensure the right amount of oxygen. To reduce the risk of particle and gas emissions, the fire must reach a minimum temperature of 750° C in the shortest possible time. HWAM® SmartControl™ helps adjust the position of the vents to achieve this temperature.

Denmark has the strictest legal requirements in Europe when it comes to particle emissions from wood-burning stoves. Therefore, you can light the fire with a clear conscience, sit back and enjoy while the wood-burning stove does all the hard work.

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 and HWAM 5530 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.

Here at HWAM, we have been working with sheet iron for more than 45 years, and we know what advantages it provides for our customers.

Most wood-burning stoves today are made of sheet iron. Sheet iron gives the opportunity to make designs that are not possible with cast iron.

Its smooth surface gives the wood-burning stove the same finish as other pieces of furniture in the house. Furthermore, sheet iron begins to radiate heat upon lighting the stove. The melting point of sheet iron is 1,600 degrees, while that of cast iron is only 1,200 degrees. Cast iron can also crack if heated too quickly, which is impossible with sheet iron.
