Check out how Paloma water heaters from PH2-25 series are designed to use sophisticated features to optimize the combustion, increase the performance and safety of the unit.
Powerful Paloma tankless water heaters from 8.4 series are recommended for homes with one to three bathrooms, as they can provide up to 8.4 gallons per minute of hot water. That means longer showers and baths, plus dishwashing, with endless hot water when you needed it.
Higher flow rates can be met in the southern warmer climates where the water heater can be used as the whole-house unit, while in the northern and colder regions, where the incoming water is cooler, Paloma PH2-25 is used in smaller homes or for point of use service.
Like other models from Paloma, PH2-25 is still energy efficient with 30 % or more energy savings than the tank-type units.
They are factory built to use the natural gas but can be bought or converted (by the certified installer) to use propane gas, with the energy efficiency of 84%, which makes them Energy Star compliant.
Paloma PH2-25 series offers two types of tankless water heaters, an outdoor PH2-25ROFN, and direct-vent or indoor model PH2-25RDVSN, with the 3"/5" concentric venting kit for safe exhaust and intake of the fresh air. The modulating gas valve allows them to work in the power range from 11,000 to 180,000 BTU and produce water flow from 0.44 to 8.4 gallons per minute.
The units are excellent in providing hot water on demand and in continuous supply, but they are restricted by how much hot water they can provide. This is why Paloma recommends using the DUOnex system to connect two units into one and give even more hot water. When two Paloma units are combined into one DUOnex system, the first-hour delivery can reach high 480 gallons.
Endless and on-demand hot water.
Paloma tankless water heaters from the PH2-25 series are mainly used for heating potable water but can be used as part of the circulating water system. It comes with the 12-year warranty on the heat exchanger and five on other elements. To have a valid warranty and use the unit for a long time, proper maintenance and preparation should be performed regularly.
