The many advantages of continuous flow systems

  • never run out of hot water, regardless of how long your teenagers are in the shower
  • only pay to heat the water you actually use
  • the compact unit is easily installed in small yards making it ideal for units, townhouses, and inner-city homes
  • LPG and natural gas models available
  • indoor and outdoor fitted options
  • condensing systems are up to 90% energy efficient
  • most of the leading brands offer 6 or 7 Star energy rated options
  • 20-year useful life - storage units last about 10 years
  • no issues with storing water at + 60°C to prevent bacteria growth and adjusting the delivery temperature to 50°C for safety. Simply set the desired delivery temperature at the unit for instant results.

What size tankless water heater do I need?

Unlike storage hot water systems, estimating the right tankless unit for your needs is a little more involved. As the unit will continuously produce heated water the number of people in your home is not as important. The major factor is how many outlets will be used at the same time.

For instance, if there are 3 showers in your home and all of them are used at once every night, you'll need a larger unit than a home with 3 bathrooms but only one shower in use at a time. Simultaneous kitchen water needs also need to be considered.
