What is the difference in "Digital" natural gas and "Millivolt" natural gas?
I'm set on a Raypak 399K btu, but dont know the difference between the 2...
There is also a "Cupro-Nickle" model and a Low-Nox version.
Swim season will be from Mid May till late September probably with this heater. Close it down around mid October and Open it up in late April/early May. Heater will be under a enclosed deck near the pool. Heater will be placed in a part of the deck with about 5' head room and plenty of room to work around and maneuver.
Anyone shed some light on these? They are all within $300 of each other.
