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 full output this heater will draw a minimum of 51a and so it is recommended to fit an upgraded alternator to cope with the additional electrical load, if you run the stock alternator you are still able to run the heater at full output but 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 are not a replacement for Diesel or Gas powered heaters, if you need something powerful then 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 period of time then the electric heater will suit your requirements. At full out put this 600w heater will drain a 110a/hr leisure in battery in approximately 1 hour 45 minutes. As you can see there are pro's and con's to every type of heating system! If you are in doubt about 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 which 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 in case any temperature sensitive items or equipment is installed or stored within the vicinity of the heater.
