Cascade Up To 12 Tankless Water Heaters for Maximum Usage Capabilities


  • Energy Efficient – only turns on when you need hot water. When the hot water demand stops, the unit turns off.
  • Saves Money – because the unit only uses energy when it’s heating the water, you only pay for energy when the unit is actually working.
  • Saves Space – tankless heaters heat the water only as you need it so they don’t require a large storage tank and use less space in your utility room.
  • Long Life Span – because water is constantly flowing through the unit instead of sitting idle in a tank, tankless units are not prone to corrosion and can have a life span twice as long as a conventional water tank.
  • Endless hot water – the heating element adjusts based on how much hot water is needed giving you endless hot water for as long as you need it.


  • Limited Usage for Multiple Outlets – tankless units limit to how much water can be heated at a single time. You may not be able to run a dishwasher, washing machine, and shower at the same time and get the same hot water quality unless you install more than one tankless water heater.
  • Power Outage – These heaters need electricity in order to regulate the temperatures. If the power goes out, so does your hot water.
  • Unit Cost – the initial cost of a tankless hot water system might cause you to think twice, especially if you need more than one to get the same hot water consistency for multiple outlets.
  • Tank Conversion Installations – if you currently have a conventional tank water heater, converting to a tankless system may require additional cost for modifications to accommodate the new system.

How Tankless Water Heaters Work

Tankless Water Heaters provide hot water only when you need it, and stop heating the water when you don’t need it, resulting in a more efficient use of energy. You have the benefit of limitless hot water without wasting energy.

  1. When a hot water tap is opened, the tankless water heater detects the flow
  2. The flow sensor activates to determine the amount of hot water needed
  3. The igniter activates
  4. The gas control valve opens to supply the correct amount of gas
  5. The fan and venturi activate to provide the correct amount of gas and fuel
  6. The premix burner ignites providing a flame to heat the water
  7. Cold water is pre-heated in the secondary heat exchanger
  8. Pre-heated water passes from the secondary to the primary heat exchanger
  9. The unit determines outgoing set temperature and adjusts the flame to heat the water
  10. Heated water moves to the buffer tank
  11. Desired hot water amount delivered to the faucet
