Today, we want everything fast-paced. We become impatient and unwilling to wait for many things, and that includes hot water. Whether you are washing your hands, the dishes or taking a shower, you want hot water immediately. You may have heard about tank-less water heaters and how they provide instant hot water.

How did a Tank-less Water Heater work?
  1. When a hot water tap is turned on, cold water travels through a pipe into the unit.
  2. The water flow is detected by a sensor that ignites the gas burner, to heat the water in the heat exchanger.
  3. The water typically follows a serpentine pattern through the heat exchanger, absorbing as much heat as possible.
  4. An electronic control unit modulates the gas burner to maintain set water temperature.
Why choose a Tank-less Instant Hot Water System?

A Virtually Endless Supply of Hot Water

A traditional storage tank hot water heaters can only heat a certain number of liters at a time. Pre-heated water in the tank once used up needs a recovery period to get the fresh contents back up to an acceptable temperature.

The tankless hot water system, on the other hand, heats water when you need it and can maintain an indefinite flow rate. You won’t run out of the water no matter how many shower lines are turned on.

Lower Energy Bills

The large tank requires a lot of energy to maintain the temperature of the stored ware 24/7. Tank-less hot water systems have a burner that only needs to run when the hot water is needed.

Space Savings

Removing bulky storage tank saves space. Tank-less water heaters are a fraction of the size of a traditional storage tank heater, about the size of a small suitcase. Also, smaller units are more aesthetically pleasing because it doesn’t dominate the exterior of your home.

Reduced Emissions

Tank-less hot water heaters reduce greenhouse gas emissions, about a third of what electric storage hot water system produces.

Longevity

Traditional storage tank water heaters have a lifespan of around 10 to 12 years while a tank-less hot water system lasts up to 20 years.

Cleaner, Fresher and Healthier Water

Water from a storage tank may build up bits of rust and scale within. In, tank-less system since no tank to rust and no water to store. The water stays cleaner and fresher. You only need to heat the water to 50°C, as the prevention of bacterial growth is NOT an issue with tank-less units. 

What size of Hot Water System do you need?

Simultaneous use is one of the fundamental determining factors. The number of people in your home combined with how and when they use hot water.

  • How many people are there in the household?
  • Do they all take showers at the same time of day?
  • Do they take showers simultaneously in different bathrooms?
  • Do the showers have WELS 3 Star Rated Showerheads (maximum 9 Lt/Min) or standard 18 to 25 Lt/Min shower heads?
  • Do some prefer baths, which use more hot water? Is the bath or spa oversized, requiring even hotter water?
  • Do you run the washing machine, using hot or warm water, while people are showering?
  • Is your dishwasher connected to the cold or hot water? If hot, do you use it while hot water is being used elsewhere?
  • Do you live in a cold climate with cold incoming weather?
