Models

paloma condensing water heaters phh32

Paloma condensing water heaters are designed for an outdoor and indoor installation, and with the compact, space-saving design they are ideal for the wall mount.

Outdoor model PHH-32ROFN can be installed outside only, usually inside the recess box, and with the built-in electric blower the venting system is not required.

Indoor model PHH-32RDVN is the sealed combustion, direct vent water heater, which, thanks to the condensing technology uses the affordable PVC venting, vs. non-condensing water heaters that use expensive stainless steel pipes.

Thanks to the built-in electric blower, flexible 2-pipe direct vent system and the sealed combustion, the flue gases as the products of the gas combustion are transferred outside safely, making the water heater great for installation anywhere inside the house.

Features

Power and water flow

Paloma tankless water heaters work within the power range from 11,000 to 199,900 Btu/hr, thanks to the modulation gas control valve and the burner, while the water flow runs from the minimum 0.4 gallons per minute to high 9.5 GPM when the unit runs with the highest power. This is what makes these Paloma heaters ideal for homes with two to three baths.

ICAD

Paloma PHH-32RDVN offers the exclusive sensing burner and ICAD Safety System, which monitors and optimizes gas combustion and shuts down the unit in a case of the increased level of carbon monoxide.

Diagnostic system

Self diagnostic system is built into the heater. If there is a problem with the unit, an error code appears on the LED display of a remote control. These codes are as follows: 1L, 05, 11, 12, 13... This article provides more info about the tankless problems you might experience and this one how properly to maintain the tankless unit.

Remote control

Digital remote control provide not only convenience to change the temperature of hot water but comfort and peace of mind to monitor the operation of the heater.

DUOnex system

As said before, Paloma condensing water heaters from PHH-32 series are with the maximum water flow of 9.5 GPM ideal for two to three bath homes, but thanks to its easy expansion capability and DUOnex system they can combine the power of two units into one and provide even more hot water, which is great for high demanding homes. With an optional MIC-185 even larger system, up to 20 units, can be combined.

Safety devices

  • ICAD - Incomplete Combustion Avoidance Device
  • Overheat film wrap, which wraps the heat exchanger and detects the unsafe overheating at its early stage.

  • Three flame rods to monitor flame failure.

  • High-limit switch for hot water temperature.

  • High-limit switch for the flue temperature.

  • Freeze protection up to -30 F.

Paloma condensing water heaters are mainly designed for residential use, but can be converted for commercial installation so the maximum temperature of hot water now changes to higher 185 F, and installed as part of the circulating water system. The warranty is 12-years on the heat exchanger and 5 on parts.
