Tankless units heat water only when you need it.  So you save money and reduce waste by not heating and reheating the same tank of water.

When there is a demand for hot water, the unit senses the flow and starts the heating process.  This results in hot water that is not limited to what’s available in your tank, so you always have clean, hot water when you want it for as long as you need it!  When the demand for hot water ceases, the tankless unit shuts down and uses no energy.

Sequence of operation

  1. A hot water tap is opened such as a kitchen / bath faucet, shower, tub or washing machine
  2. The water flow through the tankless water heater detects the call for hot water
  3. The water flow turbine sends a signal to the control board which looks at multiple factors:
    1. Incoming water temperature
    2. Desired water temperature as set on the temperature controller
    3. Calculated difference between the two temperatures
  4. Depending on the calculated incoming and desired water temperatures, the gas flow into the burner assembly is modulated
  5. The electronic ignition sequence begins
  6. Water is heated to the desired temperature as it circulates through the copper heat exchanger providing endless hot water
  7. When the hot water tap is turned off, the tankless water heater sequentially shuts down and is placed in a standby mode pending the next call for hot water

What makes Tankless “Green”?

Superior hot water technology delivers greater efficiency and reliability, so everyone benefits – with environmental preservation and energy conservation that results in a better planet for us all.

Reduced Energy and Operating Costs

Tankless water heaters reduce energy consumption by up to 40% by heating water only on demand and avoiding standby loss.

Water Conservation

The compact design of a tankless water allows flexibility with installation so it can be located closer to fixtures and appliances, saving on water consumption because the “wait” time for hot water is reduced.

Cleaner Air and a Healthier Home

Tankless water heaters produce very low NOx (less than 40 PPM) and CO2 emissions, contributing to cleaner air and a healthier home and making it an environmentally sound gas appliance.

Protecting Natural Resources

With up to a 20-year service life, Tankless water heaters last 2-3 times longer and are significantly smaller in size than traditional tank water heaters, thus reducing the amount of material that ends up in landfills.

The primary components of tankless water heaters – including the copper heat exchanger and stainless steel burners – are recyclable.

Endless Hot Water

Never take another cold shower again!  tankless water heaters heat water on demand, so you’re never limited to a fixed pre-heated supply as with a tank.  You’ll enjoy hot water when you want it, for as long as you need it.  Take a shower, wash dishes and do laundry all at the same time!

Energy Costs

With tankless water heaters, you’ll enjoy up to 40% energy savings.  That’s because our units are designed to be highly efficient and only heat water when it’s needed.  When the demand for water ceases, the unit shuts down and uses no energy, a revolutionary advantage over inefficient tank-style heaters.

Clean, Fresh Water

When using a traditional tank-style water heater, rust and scale build-up can collect in the interior of the tank, where the hot water you use day-to-day for bathing and drinking is stored.  With tankless water heaters there is no tank to store water, so you’ll always experience fresh, clean hot water because these units heats water on demand as it passes through the unit.

Space Savings and Flexible Installation Options

Reclaim precious space in your home.  Traditional tank water heaters can take up to 16 square feet of valuable floor space.  However, tankless units are about the size of a carry-on suitcase- can be installed on virtually any wall inside or outside of your home.

Peace of Mind

With tankless water heaters, there’s no tank to leak or break, thus reducing the risk of flooding.  Plus, they offer a line of digital controllers that make it easy to set water temperatures precisely to ensure comfort and prevent scalding accidents.
