3.5kw Lightweight Heater 24v
The 3.5kw Lightweight Heater is our second smallest and lightest hot water based heater after the 2.2kw Micro Heater, sacrificing a little weight for performance this unit can be used as a more powerful defrost heater and can also provide more cabin heat.
The 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 4x 51mm (2") outlet nozzles. The Axial fans are at minimum 50% lighter and use 25% of the power over traditional centrifugal blowers.
The 3.5kw Lightweight Heater is ideal for use in vehicles for defrosting windscreens, or as a backup heating device for vehicles if you already have a heated windscreen. If you have a large windscreen you can hook up all 4 outlets to feed the windscreen, or in medium sized vehicles you can utilise two outlets for defrost and two for dash or foot well vents.
Typical weight savings over a production vehicle heating system can be in excess of 6kg.
