For those who use tankless water heaters to wash horses, what gallon-per-minute flow rate can accommodate a reasonably comfortable hose, wash, and rinse?
I’m considering a Camplux portable propane heater, which I can buy locally. Camplux offers 1.32gpm, 1.58gpm, and 2.11gpm. In comparison, the InstaHot system, marketed specifically for horses, comes in 1.4gpm, 2.7gpm, and 3gpm. So I’m guessing flow rates in this ballpark work?
Of course, more gpm = more $. If the 2.11gpm Camplux is the way to go, I’d justify the extra cost. But for my needs, I don’t want to spend the extra money just because 2.11gpm is “more” and therefore “must be better” if a lesser flow rate will do just fine.
I want this for the occasional, pre-clip bath in fair weather (60F - low 70F) when it’s warm enough for an outside bath but still too chilly to comfortably offset cold hose water. At the moment, my Cushings guy and hairy pony need to be clipped but it’s a little chilly for their comfort (and mine) for a cold water wash. I usually wait until the weather is warm enough for them to tolerate a cold water bath (more or less) but the weather and my schedule don’t always work out. I’m ready to depend more on something that will allow me to bathe and clip around my schedule, not Mother Nature’s.
