    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 100 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.
  • Tank-in-Tank Efficiency
  • Using boiler water as a heat source for the Smart 100 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.
  • 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 100 is contoured to promote water movement. This design prevents lime build-up in your water heater and keeps it running efficiently.

Please explain "indirect fired." Does it need to be connected to a existing boiler?
