Capacity: 3 Showers + 1 Appliance
Flow Rate: 0.5 to 9.0 GPM
Max Temp. Range: Up to 185ºF
Gas Inputs: 13,000-199,000 Btu/h
Energy Factor: 0.93%
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 change in temperature 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.

T-H2-DV Tankless Two are better than One
By John the pilot
from St. Charles, Missouri
Comments about T-H2-DV Takagi Tankless Water Heater, Direct Vent (Natural Gas):
In my first review, We had just the first one installed (see previous review and pictures). I also stated based on "actual operating conditions" we would need a second unit and that Laclede Gas Company would be upgrading our meter to 400,000 BTU.An exact analysis was done to determine the maximum possible BTU burn with all appliances in our home (Furnace, Gas Cook-top, Gas Dryer & Two Tankless Systems). Our burn rate could exceed 700,000 BTU/hour. Based on these findings, our Natural Gas Service Line was replaced with a 1 inch PSI line vs. the WC line we had before (WC = Water Column Inches; form of measurement for Natural Gas). We have a new meter with this service with two lines going into the home. The "original" line is for all the appliances except the new T-H2-DV Tankless Systems. The original line has an "Inches to WC" pressure regulator mounted outside the home on the Gas meter. The second line is 3/4 black pipe but is under a constant 2 PSI to the two Tankless Units. There are then 2 Maxtrol 325-5AL inches to WC pressure regulators; one for each unit (see new photos). Important to note: Laclede Gas Company did not charge one red cent for the upgraded service line or new meter! They included the outside Maxtrol Inches to WC pressure regulator and I bought the two for inside the home. I spent just over $100 for both. MAKE SURE THAT YOU GET THESE REGULATORS THAT ARE NON-VENTED IF THEY ARE INSIDE YOUR HOME!Ok, so how do the two systems work? Awesome! When high demand is needed, both systems fire up and provide as much as 12 GPM at 185 degrees. We need this very high temperature for "virus" kill. The T-H2-DV comes with an "easy link" cable with each unit so the units can "communicate" when linked together. I inquired about a longer "easy link" cable as my units would be spaced too far apart for one cable in addition to running the cable within conduit. I ended up splicing the two cables which gave me plenty of length. There are only two 18G wires so splicing was not an issue and the two wires are of different color so no worry about cross connection.It's interesting to note that when only one unit is needed, they alternate use. Therefore, I won't worry about one unit being used more than another.Great product [...]Install time for second unit with modifications to the gas line and plumbing was under 8 hours.
Bottom Line Yes, I would recommend this to a friend

T-H2-DV-LP TAKAGI TANKLESS WATER HEATER
from Asheville, NC
Comments about T-H2-DV Takagi Tankless Water Heater, Direct Vent (Propane):
It has been 3 weeks I have installed the T-H2-DV-LP TAKAGI TANKLESS WATER HEATER and it has beeen working great. I have not seen the Propane bill yet so no clue how much energy savings I got from changing the old tank heater to tankless heater.

T-H2-DV Tankless Wonder!
We live in the midwest. It's January and our inlet water temperature is 42 degrees. Based on actual running conditions, we really need two units and have since ordered the second unit to increase our flow rate. We can adequately run the shower, dishwasher and washing machine at the same time and have very good hot water! However, to fill our Jacuzzi tub at a good rate, we need the second unit.We have had our gas meter outside upgraded to 400,000 BTU per hour whereas we had 1/2 of that before. The utility company did not charge us for the upgrade. If you don't have a water softener and you have hard water issues, make sure you protect your investment with a softener so you won't have a shortened life from your tankless system.We also purchased the temperature controller so we could run the temperature of the water up to 185 degrees to kill virus's should the kids get colds or the flu when washing the dishes. My wife also uses this setting for very hot water for the washing machine. Works great with the high efficiency washing machine units. If you don't get the remote controller the temperature is factory set at 125 degrees. If you do get the controller, the instructions are with the controller how to set the temperature availability up to 185 degrees. The programming is done at the remote controller and not the dip switches on the T-H2-DV.The isolation valve kits are a must if you need to service the unit, such as cleaning out the cold water inlet filter. Without these valves, you would have to turn off the water to the whole home. Not smart idea. Good choice in doing this and it makes for a cleaner install.We also got a concentric vent termination kit (TH-CVPC33) which is three inch PVC kit so it has a clean look outside. It has such a nice look, we are looking at seeing if this kit will also work on our high efficency furnace so we can have a more uniform look on the side of our home.All in all, a great product! We did our homework. Takagi is the best of the best and if you are looking at running more than one unit, you can hook up to four units to get flow rates into the 30 gpm range of endless hot water.Great product and great service from Pex Supply.PS.. I'm not a plumber or electrician. I can do remodeling and I did the install myself with the help of my son in one afternoon. If you have to get this installed, get several bids and diagrams of how they will do the plumbing, gas and exhaust. Keep in mind if you want to add another unit later, make sure they account for that in the install.
