Powered flue fan-assisted heaters (Kestrel)

Kestrel 150S

Our Kestrel 150S powered flue fan-assisted heater provides ideal heating for smaller building spaces. With a maximum output of 4.4kW, it is the smallest heater in our powered flue range, but effectively achieves up to 93.9% heating efficiency, so can help building owners lower their running costs.

Unlike most gas heaters which burn oxygen from the room, our Kestrel 150S wall heater does not take air from the interior to support combustion, so it provides long-lasting, efficient and comfortable heating without reducing room air quality.

Our Kestrel 150S powered flue gas heater has an integral thermostat where all the controls are contained inside a lockable compartment and can be supplied with safety guards, if required. It can also be configured for natural gas or propane.

All of our powered flue fan-assisted heaters come with a 1 year warranty and 5 years heat exchanger warranty.
