12v 400w Ducted Electric Cab Heater

The T7design 12v DC 400w electric heater is perfect for many applications that require a fume-free and reliable heating system. These units are designed, manufactured and hand-assembled by T7Design Ltd. This unit is also available in 600w output.
Our heaters are designed to be safe and reliable. We have chosen high-quality brand name components manufactured by the leaders in their respective fields.

Applications

Our electric heaters have been installed in all sorts of applications, including:

VW Beetle, Porsches & Other Air-Cooled Vehicles:

Perfect as a source of heating & defrosting for vehicles that have been fitted with an aftermarket exhaust system or no longer have the original exhaust based heating system altogether.

At maximum output, this heater will draw a minimum of 51a, so it is recommended to fit an upgraded alternator to cope with the additional electrical load. If you run a stock alternator, you can still run the heater at its maximum output; however, only for a short period of time before you need to turn the heater down or turn it off entirely to allow your battery enough time to recharge.

VW Campers/Transporters & Other Converted Vans:

These units cannot replace Diesel or Gas powered heaters; if you need something powerful, you can't beat systems manufactured by Eberspacher, Webasto or Propex. However, if you only need something to warm your interior space to take the chill out of the air for a short time, then the electric heater will suit your requirements. This 600w heater will drain a 110a/hr leisure battery at the total output in approximately 1 hour 45 minutes. As you can see, there are pros and cons to every type of heating system! If you doubt what heating system best fits your requirements, please don't hesitate to give us a call.

Design & Safety

Only the safest heating elements are used. Not only is the surface of the heating element fully electrically insulated, but it is also mounted within a non-conductive and temperature-resistant housing. The heater elements are self-limiting, this means the closer they get to their maximum temperature threshold, the less current they draw, and the less power is dissipated.

Without airflow, the highest temperature the element can reach is approx. 285°c, this is far lower than traditional Resistive Wire, which can get as 480°c and Quartz Halogen at 500 - 1500°c. Another advantage of lower operating temperatures is the increase in useful life; the less extreme running temperatures, the longer component life you would expect to achieve.

In the unlikely case of a total fan failure, we have included a 'single use' thermal fuse into our design. If the internal temperature reaches 110°c, the fuse will break contact, shutting off the power to the heating elements. Even so, the unit would be fine acting as a convection heater. However, it's wise to play it safe if any temperature-sensitive items or equipment is installed or stored within the vicinity of the heater.
