Demand Duo

Delivers on Demand.

Rinnai’s Demand Duo system links from one to six of our highly efficient heavy-duty continuous flow water heaters to a heavily insulated stainless steel storage tank. The linking of water heaters to a storage tank, allows for short periods of peak hot water use that are greater than the continuous flow rate the water heaters can achieve on their own. Using new controller technology that offers various temperature settings and a host of other features you can't go wrong with a Demand Duo.

Whats more the Demand Duo 1 is the perfect solution to replace your existing storage hot water heater with no changes required to the water pipes.

We recommend the installation of a Demand Duo system when hot water consumption has a predictable volume. This is usually based on the number of people living in a particular building and their hot water usage or industrial machines that require regular peaks of water.

The Demand Duo unit is often used on flow and return systems that distribute the water around a building.
