LPG regulators also have different flow or PSI limits. For large items that require a lot more LPG you need to have the regulator that matches your appliance needs. A pool heater requires a large amount of gas as our Wolf equipment keeping in mind that we can be using one burner vs 12 plus ovens and fryer. That was part of our problem.
On demand hot water heaters? We have a fancy one that we can adjust the LPG heating temp. and the on/off ?? of the supplied water PSI. The shower temp. is perfect until the water pump kicks in, 40/60 psi and then we are either boil or freeze. Years of this and could never find the "magic" settings. As someone else said............. keep it simple. No more fancy HwH.
