The 2.2kw Micro Heater is the smallest and lightest hot water based heater available making it perfect for applications where weight or space is the number one priority.
The heater uses a specially designed copper & brass heater core which utilises micro tube technology, a high fin density and thin tube walls offer exceptional heat exchanger performance in a very small package.
A lightweight axial fan is used to draw air through the heater core and expel it through the single 2.5" outlet nozzle, these types of fans are at minimum 50% lighter and use 25% of the power over traditional centrifugal blowers.
The Micro 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. These work perfectly with one or two of our universal defrost vents feeding the windscreen. If you are going to utilise the vehicles existing full width defrost vents and under dash ducting then it is recommend to use a larger model of heater.
Typical weight savings over a production vehicle heating system can be in excess of 6kg.

The fan has no onboard speed control, the simplest way to operate this fan is to use an ON/OFF toggle or rocker switch. If you would like to adjust the fan speed please see our PWM fan controller.
Please ensure your supply is fused appropriately, it is recommended to use a 3a fuse and that your cable is rated higher than the fuse.
Please note that a corrosion inhibitor such as glycol or anti-freeze should be used to prevent corrosion and prolong the useful life of all components used in the vehicles cooling system.
Not suitable for use in cooling systems that run at pressure higher than 2 bar (28 psi).
