I just bought a Pro-Heat hydronic unit from a large auction site. I was looking on this same site and found a system that automaticly extracts air from the closed loop systems. It has an "air scoop"valve an "air discharge vent" a "regulator valve" and a "4 gal expansion tank pressurized to 12psi".
Would this be helpful for my Pro-Heat setup?
Do any of you with these type of systems ever have problems with air getting in your systems and locking up the flow?

Dear Nelson,
Not if the system is properly installed and properly bled.
If your system is closed, and you use distilled water, a properly bled system shouldn't have an aeration problem.

The necessary expansion tank will help with the change in volume the water goes thru as it heats.
Remember that antifreez has only 5/8 the heat transfer ability of just water , so if the coach doesn't see -40 often parked unheated , only about 1/3 of the circ fluid need be antifreez . the rest dist water.
Be sure to create schematics of the electric and all water piping / valves etc as these are a nightmare to trouble shoot at O' Dark 30 .

I have an 80K btu Webasto 2020. Includes an elec water pump & with that and the engine running I never need to purge. If ever you're going to run the system seperate from the engine cooling loop, then the extra expansion tank would be required or you would have big leaks. But I would recommend always keeping the two connected. Call the folks that sell the Webasto, they are a big help.
