Girard Tankless gswh-2


Hello - Does anyone have this tankless water heater? Running into issues with mine, had it installed by the dealer before picking up. The problem is the temp is not consistent at all. One second it's piping hot and the next it's freezing cold. I have a 50 psi regulator and propane tank is full. First I thought maybe the campsite was low pressured, but I have been to 5 different campsites and its the same thing. No other faucets are on during showers.
