Paloma Industries is the #1 gas appliance manufacturer in Japan. The Paloma outdoor models incorporate a unique safety feature not found on competitive tankless gas water heaters.

The FILM TYPE OVERHEAT LIMITER senses high temperature at all positions surrounding the combustion chamber. Other manufactures only sense at one point on the combustion chamber.

Three remote controls (one main control and two bath remote controls) can be installed together. One main remote control (UMC-117) comes with each unit.

WARRANTY*
12 Year warranty on heat exchanger
5 Year warranty on parts
1 Year warranty on service
*Effective on all water heaters purchased after 07-01-2008
