Kunzel™ Pellet-One
Indoor Wood Pellet Boiler from Aqua-Therm


Aqua-Therm is proud to be the exclusive distributor of high efficiency German engineered  Kunzel  Pellet-One Indoor Wood Pellet boilers.

The  Pellet-One   is available in two sizes to easily supply the heating and domestic water needs for residential and small to medium sized commercial or office applications.

The Pellet-One comes with a five-year Limited Warranty.

Like our other boilers, it can be easily integrated with existing heating systems while offering the convenience of wood pellet fuel.

The  Pellet-One systems  can be installed with proprietary automatic fuel feeder systems and by utilizing state of the art microprocessor controllers, provide a continuous maintenance free fuel supply for extended periods.  The only limitation is the size of the fuel hopper connected to the boiler.

An appropriately sized fuel hopper is available for residential use while custom solutions are available for larger system requirements and commercial installations.
Cleaning and servicing is easy: The practical front-mounted burner unit can be swung out wide to make the inner parts accessible.
The overall dimensions of the boiler are small and manageable thanks to the compactly built heat exchanger.
The differential temperature controller automatically controls burner and boiler circulation pump with just a few prior settings by the installer.
