T7Design 3.5kw Lightweight Heater with Side Vents 12v

3.5kw Lightweight Heater with Side Vents 12v

The 3.5kw Lightweight Heater with Side Vents is our second smallest and lightest hot water-based heater after the 2.2kw Micro Heater, sacrificing a little weight for more performance this unit can be used as a more powerful defrost heater and can also provide more cabin heat. The side vents version incorporates two adjustable lower vents to blow air direct into the footwells of the cabin and up to 3 positions in the top half of the enclosure for air ducting. There are 4 different diameters of outlet to choose from ranging from 32mm (1.25") up to 51mm (2").

PLEASE NOTE: The upper 3 options do not refer to a specific location on the heater and the outlets are supplied lose in the box for the user to rivet them in place where required. If only two vents are needed, then please chose a 'Blanking Plate' for one of the options.

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 the outlet nozzles. The Axial fans are at a 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 connect up all outlets to feed the windscreen.

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.

The dimensioned drawing shown below is for our standard 3.5kw Lightweight Heater but shares the same overall dimensions as the side vents version.
