Triangle Tube - Indirect Water Heaters prevent hot spots to extend their life

You don't need to give up performance and comfort to reduce your hot water heating costs.  Indirect water heaters can provide the performance of traditional storage type water heaters with the energy efficiency of instantaneous models.  In addition to the savings on your utility bills every month, the replacement costs can be eliminated.  

The Smart Series Indirect Water Heaters feature a stainless steel inner tank for superior corrosion resistance.  But superior materials are only half of the story.  In addition to resisting corrosion, the Smart Indirect Water Heaters feature a unique tank-in-tank design that is self cleaning and eliminate hot spots within the tank.  The stainless steel inner tank is surrounded by boiler system water in the outer tank.  This hot boiler system water is able to transfer it's heat over the entire surface of the inner tank.  This prevents the formation of hot spots within the tank.

In traditional water heaters hot spots form at the bottom of the tank in gas fired models.  In electric models the heating elements are hot spots.  And in most other indirect water heaters, the heating coil within the tank is a hot spot.  Why are hot spots a failure method?  Hot spots encourage scale formation.  The suspended minerals in water are attracted to heat, and will gather on the hottest areas in the tank.  As this scale builds up, it acts as insulation on the heating element.  This makes the hot spot hotter, encouraging more scale formation, and then insulating the hot spot further.

Eventually this area becomes so hot, that the area fails.  Tanks will fail due to the stress caused by the extreme heat.  

Triangle Tube's Smart Series Indirect Water Heaters virtually eliminate this problem.  They are backed by a lifetime replacement warranty as prove of their durability.  There are 7 sizes to choose from from 30 gallons to 120 gallons  Contact Triangle Tube or your local Triangle Tube installer for more information.
