I have a question concerning this system as our new Reflection 337 has this installed. My system seems to take several minutes to send hot water to either the kitchen sink or the shower and bathroom sink. Is this normal. During my walkthrough I was advised of the adjustment located outside on the tank, and told to leave it on the maximum setting, which it is. I’m usually hooked up to city water, and couldn’t imagine how much water I would waste waiting for it to heat up to shower, if we were boondocking. I’ve accepted the fact that hot water will cost me now because of the need for propane, but this lengthy delay is annoying. Any info would be appreciated. TIA. We love everything else about our new Reflection and probably just need to get use to this new technology.
