Triangle Tube Smart 40 - 36 Gal. - Indirect Water Heater Review Mar 30, 2016

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.

Expensive but is a nicely manufactured product.

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.

I replaced a Dunkirk XEB-3 (20 yrs. old) with the Dunkirk boiler above. The new one is all most identical to the old one, that is the pipes were located same as the old, so gas and water lines were easily plumbed. The old electrical wires could be used although lengthened to connect to the digital controls. The circulators location has changed, it's still provided with its wiring provided. Venting is the same as the old one. I was happy to get another Dunkirk that installed easily.

Great Heater I'd Buy Again😎 Aug 23, 2016

I replaced my old Modine heater, with a new Modine heater and it works great. The old one, the only thing that went wrong with it, was one of the fan blades broke in half . The old one , didn't owe me nothing, I had it in my shop for 38 years.
