Paloma Industries is the #1 gas appliance manufacturer
in Japan. The commercial model PH28CDV incorporates TWO unique safety features
not found on competitive tankless gas water heaters.
First is the OXYGEN DEPLETION SENSING system (Indoor Model Only). Emissions from
the sampling burner are constantly analyzed for carbon monoxide gas. If necessary,
the fan speed is adjusted by the on board cpu. If the fan speed adjustments do
not resolve the combustion problem, the burner will be turned off and a potentially
dangerous situation avoided. An error message will be displayed.
Second is the FILM TYPE OVERHEAT SENSING. Waiwela alone 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*
5 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
