Performance
First Hour Delivery Sometimes called First Hour Rating, this is the number of gallons of hot water the heater can supply per hour when starting with a fully heated tank.
Triangle Tube is best known for two things: feats of hydronic innovation and incredibly efficient products. These qualities are intertwined in Triangle Tube's Smart Series Indirect Fired water heaters. The Smart water heaters feature an exclusive "tank-in-tank" design that Triangle Tube has been refining for three decades. To heat domestic water, the outer tank of the Smart 50 fills with boiler water and the surface of the inner tank becomes a heat exchanger. Two inches of polyurethane insulation ensures that your domestic hot water stays hot, and stainless steel construction of the inner tank provides exceptional durability. When it comes to making a decision on your next water heater, the Smart lives up its name.
Product Features
Tank-in-Tank Efficiency The tank-in-tank design of Smart Series water heaters uses less energy to heat your domestic water supply. Using boiler water as a heat source for the Smart 50 means that whenever your boiler fires it is providing heat not just for your home, but for your water as well.
Tank-in-Tank Safety High temperatures prevent the growth of bacteria. High quality stainless steel and Triangle Tube's tank-in-tank design allow your domestic hot water to be stored at higher temperatures than traditional water heaters, providing peace of mind in every application.
Incredible Recovery Rate The large surface area of the inner tank means that water is heated very quickly. Smart Series Indirect Fired water heaters boast a recovery rate up to 300% greater than that of conventional water heaters.
Self-Cleaning The inner tank of the Smart 50 is contoured to promote water movement. This design prevents lime build-up in your water heater and keeps it running efficiently.

Q: Please explain "indirect fired." Does it need to be connected to a existing boiler? by Fernando from District of Columbia on September 13, 2015
A: An indirect fired water heater is a storage tank with a coil inside and inlet and outlet taps (connection points). The indirect fired water heater is installed as a separate zone, circulating hot water from the boiler to a coil inside the indirect fired water heater.
I ordered Triangle Tube's SMART 50 indirect water heater six months ago when my previous tank was near failure and leaking profusely after 23.5 years of service. It was delivered promptly to my home in perfect condition. My plumber installed it that week and it has reliably provided hot water ever since.
I have a boiler system that heats my home via 3 separate circuits, and another circuit dedicated to this tank. My plumber recommended this brand as a result of his experience, and I have been very satisfied so far. This well-insulated tank has reduced my utility bills as well.

"My experience with eComfort was exceptional. My product was delivered promptly and in perfect condition."
We live in a ski town and though usually only two retirees in the home, we sometimes have 12-15 skiers and snow-players as guests. We need lots of hot water. Our plumber was concerned about the touted online performance rating of the Smart 80 (gallons first hour, etc.).
Not to worry! With proper attention to the pump capacity and boiler supply and return pipe sizing, we are delivering 100,000 BTH/H with our Triangle Tube Prestige 175, and we have all the hot water a 3-bath home can use with this setup. Love the construction, look/feel, and long warranty. Great unit!

It works good except mine started leaking all over the floor inside of 2 yrs and now my contractor says he hasn't heard from the dealer for the warranty. No drain in on the unit so I can't just move it out of my basement.

Replaced a 22 year old Triangle tube heater with the Smart 40. My furnace hardly ever runs to keep my hot water hot unless I am using it. Really holds the heat. I have had it installed about a month now and I think it was a great purchase. A little expensive, but if it last as long as my last one, I'll be happy.
