In theory you can adjust the fuel pump for altitude by using a pump with a lower dosage. Then the frequency is high enough even at lower fuel amounts to avoid starvation of the flame. Newer heaters do it that way.
Thank you for the good video. I have my ram promaster 159 extended, tall roof, almost done. It is time to put in my heater. Trying to decide between these two. The van is 365 use. All tanks are on the inside of the van. It is well insulated. There is no 'garage', it is all living space. We will cover windows and will isolate the cab from the living compartment when it is cold. Will the 2000 STC be enough?
He didn''t want to answer the question as he represents Webasto. Regularly use the STC 2000 over 7000' with no issues. Keep a window cracked and your fan on a 10-20% out. No issues for over 4 years!
I have used the STC 2000 regularly over 7000' and a couple of times over 10K feet. keep a window cracked and if you have a fan run it 10-20% out and you should be fine. Been doing this over 4 years!
You reference the evo 40 at 6800 BTU’s while the manufacturers site says it’s actually around 13,000 BTU’s.

Very informative thank you.

Yes it is more than enough. I have a similar van and that heater keeps me toasty!
Glad they made a high altitude evo 40 now
That webasto guy never got to the bottom of the issue tho
Hi David, what do you want to know about that we might be able to answer or get an answer to?

Hmmmm, I am often over 8,000 feet . Can I even use the EVO40? Plus I live part of the year at only 900 feet. Sigh.
