The T-H2, Takagi's greenest model, is the 2nd
Generation High Efficiency Tankless unit with an average efficiency of
92% with natural gas (estimated) and 95% 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. With a
variable gas input up from 13,000 Btu/h to 199,000 Btu/h and with its
high efficiency, the T-H2 can deliver 9.0 gallons (Max.) of hot water
per minute under ideal conditions and when you Easy-Link 4 units
together you can produce up to 36GPM (Max.) as a result, the unit will
meet the needs of large homes, as well as light commercial and
industrial applications. Able to deliver water up to 185ºF, the T-H2 is
appropriate for sanitary applications needing 180ºF water to meet code
requirements.
The T-H2
features sixteen temperature presets for flexibility of installation. To
achieve any temperature other than the sixteen presets, the user will
require the TM-RE30 temperature controller
