Excellent productThe water heater is excellent, high quality and a good price.
On the minus side, the truck shipping (required, due to weight) left something to be desired.

Nice! Heats my 46f water to 125 with no troublesWorked better than expected. I wanted a condensing unit so I could vent with PVC (no chimney). I did get the bigger unit since we have some cold water in the winter months (38f). This thing can heat my 46f (test day) water to 140f (highest I went) without any problems. I ran the 2 sinks, tub and washer and it reached those temps with ease. I could have went with the 160k btu unit and would have been safe. It really gets into condensing around 4gpm. Not sure how (because I never touched it after install) my tank heater lasted 19 1/2 years. It's still going but only gives 10min shower in the morning.
If this thing last close to that or longer with annual maintenance, I'll be a happy camper :) I'm still curious to see gas usage during summer (water heater and stove) using this Tankless over the tank.

Takagi TH3DV Natural Gas Tankless H2O HeaterWe replaced a battleship sized 80 gallon electric hot water tank with the Takagi TH3DV and not only did we gain great performance and efficiency but gained a storage room as well by removing the old tank and placing this shoe box size unit on the wall (actually about the size of three shoe boxes) - It delivers HOT water to the hole house without missing a beat - I even installed a spigot at the unit so I can have hot water for the garage and to wash my cars! We would recommend this unit to anyone.
