12V 500W FULLY ELECTRIC HEATER

12V 500W FULLY ELECTRIC HEATER

*NEW*

Heater specifications

 

Dimensions 

Length of box 210mm (245mm overall including duct outlets)

Width 140mm

Height 123mm

 

Power 

Input 12v – 14.5v

Elements are woven carbon fibre in glass tubes X 4

Elements rated 12v 125W

Heater output @ 12v = 500W

Current draw on max settings @ 12v = 45A (Current draw can climb to approx 55A operating circa 14v).

Heater is not designed to run on a battery that is not receiving charge, optimum output is above 13.5V

Fan is dual ball brushless and puts out 158cfm

 

Electrical and switching

Main positive and negative leads are 6mm and need to be connected directly to the vehicle battery.

Switch assembly has a negative lead that can screw to the vehicle and a positive lead with a 1A fuse that can be connected to accessories or ignition.

Main unit has a 50A bi-metallic circuit breaker installed internally.

Main unit also has two relays mounted internally, one controls low heat (2 elements) and low fan, the other controls high heat (4 elements) and high fan.

 

Controls

The fan can operate without the heater elements on, this will blow cabin temp air.  Firstly turn on ignition and rotate fan switch clockwise to get fan speed one, further again for fan speed two. 

Once a fan speed has been selected the white led surrounding the switch bezel will illuminate.

To operate heat you need at least fan speed one engaged otherwise the HEAT button will not illuminate and the heater will not heat. This is a safety feature to prevent element overheat.

Select fan speed one then press the heat button, you will see the red led around the heat button glow, this commands the heater to operate two elements and a low fan speed.

Select fan speed two and all four elements will come on as well as the high fan speed.

To turn the heat function off press the heat button a second time, the red led will go out and the heater elements will disengage.

 

Air

The unit is designed to operate in a recirculatory environment with no introduction to air sources outside the area that needs to be heated.

Air intake is at the rear of the unit and this needs to be free of any restrictions to ensure adequate operational airflow is achieved.

Air expulsion is at the front of the unit via two 61mm outlets that accept flexible duct that can be clamped to them.

Fan pushes 158cfm on high

Temp test on a 18c day in an open shed recorder circa 38c at the outlets on LOW HEAT and circa 48c on HIGH HEAT.

RECIRCULATORY environments will yield higher outlet temps.
