Hot Water Units

What Is Condensing Hot Water Units in Perth?

A condensing hot water unit is an energy-efficient water heater. While a standard water heater operates with 80 to 85% efficiency, condensing water units will provide 95%!


 While these tanks cost about two times as much as conventional water heaters, they will pay for themselves over time as they recycle the heat.

This instant water heater utilizes the same technology as a gas storage water heater does. Once the hot water has been released out of the tank, it is filled with cold water. When needed, the tank is reheated, which is controlled by the electronic control monitor.

What is the Difference Between a Condensing and Non-condensing Water Heater?

A condensing water heater will reuse the extra heat. The water vapour will only be vented when it is no longer needed, about 38 degrees C. This means great potential hot water savings.
A non-condensing water heater vents the steam with temperatures around 150 degrees C. To be vented, it will need pipes that are corrosion resistant and heat resistant channels. These types of hot water devices generally mean a higher cost of operation.

  • Is there a good return on investment for the unit you have picked?
