Aqua Hot fuel consumption (was Re: dry camping)

[Leroy Eckert]

I guess that is what I was trying to say. Not matter the configuration, if hot
water is not moving it is not possible to have continuous hydronic or radiant
heat. Well stated Pete.

going over the road, I turn off the "hydronic heat" switch
on the dash board. That keeps the burner from running, but the
circulation pumps still pump as I'm able to turn on the thermostats
and get heat from the A-H using engine heat only. This is one of
those non-intuitive Blue Bird "secret" (otherwise non-documented)
facts. I hate to admit this, but I only discovered this recently. But
I only recently discovered that the Engine Pre-Heat uses the AquaHot
to heat the engine. In my case both the "pre-heat" and the "hydronic
heat" switches must be on for it to work.

At least, it's how it works with my system.
