Rinnai’s hot water story began in the early 90s with the introduction of Rinnai Infinity. Simply translated, it meant you would never run out of hot water. M Abdulally introduced this revolutionary hot water solution in the Sri Lankan market and to this day is the only gas powered hot water heating solution in the island.

Our manifold pack consists of 2 to 25 heavy-duty continuous flow water heaters plumbed together. This allows for higher flow rates than a single unit can achieve. The outlet temperature is preset and remains constant, even when the flow varies, providing a reliable source of hot water that only uses gas when there is a 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. What’s more the Demand Duo is the perfect solution to replace your existing storage hot water heater with no changes required to the water pipes.
