How does a tankless water heater work?

  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 burner ignites providing a flame to heat the water
  6. Cold water passes through the heat exchanger
  7. The unit determines outgoing set temperature and adjusts the flame to heat the water
  8. Desired hot water amount delivered to the faucet

How much money can I save?
Depending on which make and model of tankless water heater you choose, and what size water tank you have now, and if it runs on gas or electricity, you could potentially save anywhere from 5% to 60% off your hot water heating bill. How? Most homes use hot water for a cumulative total of about one hour per day, yet they typically keep 40 or 50 gallons of water hot 24 hours a day. Having a system that eliminates the storage and heats water only as you use it can dramatically reduce your energy consumption.
Will one tankless water heater be enough to heat my entire house?
Yes. We help you choose the proper model to suit your home or building’s hot water needs, which is based upon the maximum flow of hot water you need at any one time.
How can a tankless water heater heat water instantly?
When you open a faucet, the flow of the water triggers the heater to turn on. Whether you use gas or electricity, the gas burners or electrical elements will turn on, rapidly heating the water as it passes through the unit.
What if I have hard water?
Since tankless water heaters do not store hot water, minerals have less of an opportunity to settle out of the water column and build up inside the heat exchanger. Additionally, the flow of hot water through the coiled heat exchanger flushes the product each time hot water is used. The use of a water softener is fine with a tankless water heater, and is recommended if you commonly experience hard water problems in your home.
