Product Features

HWAM® Autopilot™

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.

HWAM® SmartControl™

HWAM® SmartControl™ electronic air regulation gives you a sublime level of comfort and goes easy on the environment and on your pocket.

Materials

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.

Combustion Air System

No oxygen, no fire. It’s that simple. That is why a constant flow of air to the wood-burning stove is needed to create clean and effective combustion in your HWAM.

Convection

All HWAM wood-burning stoves are convection stoves. This means that the wood-burning stove quickly emits heat after lighting.

3 way "Airwash"

Dancing flames are both fascinating and relaxing. Furthermore, flames are beautiful in all phases from the initial lighting to the burning of coals.

Comfort

A HWAM wood-burning stove is designed for user-friendliness throughout the duration of its service lifetime.

Unique Door System

All HWAM stoves have an easy and unique closing system, which ensures that the door fits tightly
