PuroWIN DELUXE Ash container
With our 240-liter ash container, emptying intervals of up to one heating season can be achieved (depending on fuel type and boiler output). The hot-dip galvanized steel container is equipped with wheels for easier handling. A flexible screw compresses the ash further and automatically transports it into the ash container.

Full efficiency without high-voltage power
Intelligent motor control and ember maintenance reduce power consumption to just 120 watts – the PuroWIN DELUXE can be operated with a 230V connection – no high-voltage power supply is required. This saves energy costs and makes operation especially efficient.

PuroWIN DELUXE Awards
Windhager offers up to 5 years full warranty. The PuroWIN wood chip boiler has been awarded the Energy Globe Award in the Fire category and the Plus X Award in the categories Innovation, High Quality, Functionality, and Ecology. As part of the Salzburg Business Award, the PuroWIN achieved an excellent second place in the Innovation category. In addition, the PuroWIN received the Agrarfuchs Gold award from the state of Upper Austria and the German Federal Ecodesign Award from the Ministry for the Environment.
