Demand Duo Lite 180 L


Demand Duo Lite 180 L

A cost effective variant of the highly successful commercial Demand Duo range, developed especially for domestic applications. The Demand Duo Lite is comprised of an electric tank and gas boost continuous flow water heater.

Benefits at a glance

  • The high input, fast heating system ensure the storage tank refills and reheats fast
  • Heavy duty insulation minimises heat loss, to keep energy costs under control
  • Status monitor makes it easy to check on the operation of your water heater
  • System is centralised, which helps to reduce the total cost of installation


How does it work?

The thermostat senses the temperature of the water in the tank, and when it drops below the set temperature, the primary pump is activated. This in turn starts the Rinnai continous flow water heater which returns heater water to the tank. 

Suitable for
The Rinnai Demand Duo Lite is ideal for applications requiring a large, intermittant demand for hot water. For example, spa baths, large homes with multiple showers being used simultaneously, small hair salons or small laundrettes.
