Rinnai INFINITY® VT16 External

The Rinnai INFINITY® VT is a continuous flow gas hot water system for external domestic applications. This type of hot water system produces endless hot water, and is a energy efficient water heating system, because it's only on when you need hot water.

The Rinnai INFINITY® VT range has an improved minimum start-up flow rate, saving on water, and ensuring your Rinnai INFINITY® is future proofed for water efficient tapware. 


Suitable for:
• external domestic applications
• low hot water demand applications (small apartments or homes)
• mains and medium pressure systems
• solar installations as a gas boost

Hard or acidic water will need to be treated to use this product.

Gas type
