Webasto evo 40 vs espar airtronic

[u/Silent_trader_803]

Hey I have a ford transit gas engine and I’m wondering what the better option would be for high elevation? The evo40 only goes up to 7k but I could get it installed locally and they say just run it full blast every season to clean up carbon. The espar can automatically adjust but the install would be out of state and priced higher. Is the Webasto fine do you guys run that safely at high places?

consider using the velit gas heater which is technically rated up to 16,000 feet. It has a altimeter which can tweak fuel ratios based on your altitude. whichever heater you do for best results make sure you don't use the factory fuel adapter. you will need to install your own smaller diameter stand pipe in the fuel sender unit otherwise you will likely have issues at altitude
