Rinnai Infinity units can be placed inside a cupboard or even in the ceiling cavity and simply flued through the wall or roof.

As it is best to locate the unit no more than 20m from the outlet, internal units can be located centrally in the house, ensuring one unit can supply hot water to most expansive houses, requiring less piping and making installation faster.

Internal units are also ideal for upper storey apartments or townhouses where access to unobstructed exterior walls can often be difficult, or if you simply would rather not view the unit on the outside of the house.

It is important that you select the right Rinnai Continuous Flow system to deliver the optimum results. Heating capacity requirements are determined by considering how many bathrooms (and kitchens) there are in your home and also considering how much simultaneous demand there will be for hot water. This is usually affected by how many people there are in the house using hot water at one time.
