A Powerful Winter Warmer Allows You to Have a Perfect Night's Sleep
When temperatures drop outside, it is a relief to know you will be comfortable regardless of the weather. The laminar combustion in Wallas heaters produces dry, clean heat, which keeps the interior and windows dry. Fully enclosed burning process makes it smoke-and-odor-free and is relatively quiet ensuring a good night’s sleep. Wallas cottage heaters can be installed either directly through the wall or to the chimney, and minimal exhaust gas is vented outside ensuring the air is always fresh.
With a very low fuel consumption, a Wallas 33 liter (9 gal.) fuel tank will heat your cottage for almost six days. Wallas particularly recommends the Neste MY Renewable Diesel™, which is high-performing low carbon biofuel. The fuel tank is typically hidden under the cottage away from the eyes or right below the device. Energy-efficient cottage heater requires only about 0,2-04 amps, which is why a small solar panel is sufficient to recharge the battery.
A seamless Nordic design is easy on the eye, both functional and beautiful, and comes in two color options; graphite gray and winter white. It is a stylish addition to the social spaces that are the heart of your cottage.
Fully enclosed laminar burning process ensures a quiet sound level and dries the indoor air.
Low temperature on unit for everyone’s safety.
Highly energy-efficient heater saves fuel and electricity.

FUNCTIONAL DIAGRAM
Wallas heaters have a fully enclosed burning process. A fan draws combustion air in and blows the exhaust gas into the outlet through a heat recovery unit. The enclosed process ensures exhaust gas will never contaminate the indoor air.
The fuel is drawn to the burner by a pump, which allows the placement of the fuel tank for instance under the cottage, where it can be easily re-filled.
The fuel in the burner is ignited by a glow plug. The fuel vaporizes and burns with a clean, blue fire. Once ignited, the burner is constructed to maintain the heat and the glow plug turns itself off.
All the above takes place fully automatically.
