If you’re looking to upgrade from the Webasto Evo heaters, you’re in luck. All interfaces stay exactly the same as before. There is no need for changes in application and all existing accessories from Webasto dual top 6 or 8 heaters can still be used.
Webasto heaters are well known for their reliability, deadly quiet operation, and lots of heat production for both air and water. Webasto diesel heaters are also very economical to run, significantly more so than most other types of heaters.
Webasto is a global innovative systems developer founded in Germany back in 1901. Their automotive heaters have been a staple in the automotive industry since the 1960s. Webasto heaters for semi trucks, specially designed heaters for RVs and Webasto marine diesel heaters have existed since 1985.
Webasto dual purpose heaters for water and air heating - the Dual Top Evo series, launched in 2012. They are among the top 3 most popular heaters for RV’s around the globe. The Webasto dual top Evo 6 and dual top Evo 8 models are so named for the amount of heating power in kW they output.
These heaters use diesel for fuel which makes them easier to refill and cheaper to operate per BTU than propane heaters. Diesel is readily available at gas stations and you don’t need a licence to install diesel heating systems.
If you’re considering between propane and diesel heating solutions it is worth noting that diesel fuel consumption is much more efficient. Simply put if you’re looking for superior heating performance and better temperature control choose a diesel heater.
Diesel heaters are also sometimes called Webasto coolant heaters or coolant heating solutions. This is because they circulate coolant over a heat exchanger and then pump it back through the engine and HVAC system. The result is a pre-heated engine and plenty of warm air for the interior.
These Webasto heaters also double up as water heaters. As the hot coolant passes the heat exchanger it transfers its heat to plates through which water flows. The water is heated and can then be used in a tap or a shower.
In extreme climates, the heater can even be used with additional accessories to warm the fuel, hydraulic fluid and batteries.
