T-H2-OS-NG Takagi 2nd Generation High Efficiency Tankless Water Heater - Outdoor Only - Natural Gas
The T-H2, Takagi's greenest model, is the 2nd Generation High Efficiency Tankless unit with an average efficiency of 90% with natural gas (estimated) and 90% with propane (estimated). At a ∆T of 60ºF in warmer areas - where the winter ground water is 60ºF and with the output set at 120ºF - the unit will provide 6.1 GPM, or 366GPH. In other areas where the input temperature may be 40ºF or less, you can expect a flow rate of about 4.6 GPM or 276 GPH.
The T-H2 can provide at least three showers worth of water simultaneously along with one appliance at input temperature of 60ºF or greater.
The T-H2 can be vented with PVC, providing 0 clearance for DV installations. PVC venting can be used in all applications and 3" exhaust venting is coming soon. This state-of-the-art tankless water heater uses not one, but two heat exchangers to maximize the unit’s energy efficiency, resulting in the higher-than-average efficiencies stated above. The primary heat exchanger is made of "Heat Resistant Alloy" HRS35 Copper, Takagi has also added a "High Corrosion Resistant Stainless Steel" #316L secondary heat exchanger to recover waste heat from the vent stack before it leaves the unit to preheat the incoming ground water. This second heat exchanger and the resulting condensation that forms from the high efficiency operation, classify it as a "Condensing" Water Heater.
At a ∆T of 60°F in warmer areas - where the winter ground water is 60°F and with the output set at 120°F - the unit will provide 6.1 GPM, or 366GPH. In other areas where the input temperature may be 40°F or less, you can expect a flow rate of about 4.6 GPM or 276 GPH.
