Arizona LN – Warm Air Blower Box – Heater Matrix

Warm air blower boxes or fanned water heat exchangers are ideal for boats. The box is connected to a diesel water heater, much like a radiator would be. Instead of heating up like the radiator, the blower box is a water heat exchanger that uses the heat from the water to blow warm via a fan. This is a very good solution for boats that don’t have the space for radiators, or where radiators don’t fit the curvature of the hull. Warm air blower boxes can be hidden away inside cupboards and other voids to save space.
