11,900 BTU Lightweight Heater with Side Vents 12V

(2 customer reviews)


12V, 11,900 BTU lightweight water heater with two adjustable vents and up to three 2″ outlets.



Our 12V, 11,900 BTU lightweight water heater provides for a cozy cockpit, even in colder climates. It is an ideal fit homebuilt aircraft, equipped with watercooled engines, particularly Rotax, AeroMomentum and Viking.

It comes standard with two adjustable lower vents to blow air directly into the footwells of the cockpit and up to 3 positions in the top half of the enclosure for air ducting. The outlets have a diameter of 2″.

Two outlets above the adjustable vents are standard as well, a third outlet on top of the heater is additionally available.

The lightweight water heater uses a specially designed copper & brass heater core offering excellent heat transfer capabilities for its size, this is accomplished using a high flow core design, high fin density and ultra-thin wall tube.

A lightweight axial fan is used to draw air through the heater core and expel it through the outlet nozzles. The Axial fans are at a minimum 50% lighter and use 25% of the power over traditional centrifugal blowers.

    I haven’t installed the heater yet, the quality however appears to be great. I briefly hooked it up to a battery and was blown away (pun intended) by the strong airflow. Fast shipping as well.
