We just returned from Yellowstone and the water coming from the park was cold which equaled NO hot water for showers, no matter how slow you let the water flow.
Tired of this heater.... Curious to see if anyone has replaced their heater with a standard tank (not sure where it would fit) or installed another brand of heater.
Waiting for Girard to open this morning for them to tell me I don't know how to operate the unit...
Would love to have a normal water heater, with cooler / cold temps this fall in the East this fall it makes camping no fun!
Ditto your comments, but I think we've cracked the nut. We now get any range of desireable shower temp with no fluctuations.
Knowing that Berkshire tested their plumbing to a static pressure of 80 psig with no failures (but will not recommend any static (supply) pressure above 45 psig for third party component warranty considerations - like the Girard WH), I cranked my inlet pressure regulator up to 52 psig (where available), and turned the heater selection switch to "Low" (one burner operation). I now get a CONSTANT (no fluctuation)
temp choice ranging between lukewarm and too hot.
Word of caution
: Don't add any devices, fittings or tubing upstream of the WH, like a custom manifold valving at the water panel, which will cause a dynamic (flowing) pressure drop (remember - the regulator gauge shows static pressure at hookup; if you want to see how much the dynamic (flowing) ∂P is, just turn on both the hot and cold outside shower, and then read the gauge).
