Rinnai INFINITY® VT24 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.

Suitable for:
• external domestic applications
• low simultaneous hot water demand applications (homes with 1-2 bathrooms).
• mains and medium pressure systems
• solar installations as a gas boost

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