Paloma 9.5 Water Heater
(PH2-28) Review
Review of the Paloma tankless water heaters from 9.5
(PH2-28) series for homes with the high hot water demand.
Explore Paloma 9.5 top features and see how these tankless units can
save you money
and
time.
Available models
As found among other Paloma water
heaters, 9.5 series comes in two models that are used for heating
potable
water:
-
Indoor models - PH2-28RDVSN (or P for propane)
-
Outdoor - PH2-28ROFN(P)
Paloma 9.5 series are the largest non-condensing tankless
water
heaters
from this manufacturer, or models with the highest water flow and gas
input rate. The heaters can also be used as the commercial units, as
long as the conversion
(installation of the commercial chip) is done properly.
Technical data
Power and efficiency
All Paloma 9.5 tankless water heaters are designed with the
modulating gas valve, which allows them to work in the range
between the minimum power of 11,000 Btu and maximum power of
199,900 BTU, when it works in its full capacity. This power range and
the high water flow rate of 7.6 GPM ensures the comfortable
multiple-shower use, and the high thermal efficiency of
84 %, for both
propane and natural gas savings.
The energy-saving modulation won't be that efficient if there
is no help of the advanced microprocessor, which controls many
parameters during the water heating operation.
Adjusting temperature and
remote control
The operating temperature is factory set between 100 F and 120
F while the
temperatures from 85 F to 140 F can be achieved and regulated on the
Main remote control (UMC-117), which is supplied with the unit. The
remote controller is very simple, it allows you only to adjust and
monitor the
temperature in F, while the LED screen displays the water temperature,
and if
there is a problem, an error code.
Capacity and flow rate
Because of its high-volume capacity, the Paloma 9.5 models
are whole-house water heaters that are able to provide enough
hot water for up
to three simultaneous showers in colder regions (flow rate is 5.2 GPM
when the
incoming water temperature is 60 F) and even more in warmer regions
(maximum flow rate is 7.6 GPM when the incoming water temperature is
40 F).
If there is a demand for more hot water, the DUOnex
system can be used, which allows connection of the two units
into one system. Such a system known as DUO system, gives the First
Hour Rating of 525 gallons.
Venting
Paloma
9.5 water heater PH2-28RDVSN is the indoor
and direct vent model that utilizes the 3x5 stainless steel concentric
venting and the electric blower for the safe removal of the exhaust
gases out, either horizontally or vertically.
PH2-28ROFN model is the outdoor model that does not require
any venting (it uses the flue terminal), and it must not be installed
indoor or in an enclosure. Remote control is also supplied with the
outdoor models but must not be installed outdoor.
Features and Benefits
Paloma 9.5 tankless water heaters, as other Paloma models, are
equipped with the exclusive sensing burner and ICAD safety system that
optimize the combustion and protect the user if there is an increased
level of CO.
And if the water heater fails to heat the water, the
self-diagnostic program will register it, and the error code will
display on the LED screen of the remote control.
These units are very safe as they are designed
with several features, which protect against scalding, carbon
monoxide leak, fire (thanks to the Overheat Limiter Wrap), anti boil
and freezing. The freeze protection system uses the electric
heater to prevent freezing inside the water
heater, only if the temperature does not drop below 30 F.
Paloma tankless water heaters from 9.5 series come with the
12-year warranty on the heat exchanger and 5-year warranty on other
parts.
