INFINITY® VT20 External Continuous Flow Gas Hot Water System

Model: INFVT20
Rinnai Infinity VT20 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 water.
The all-new Rinnai Infinity VT range delivers:
- more speed - The Rinnai Infinity VT responds to changes in flow requirements faster than before.
- more efficiency - The Rinnai Infinity VT saves on energy use by being able to more precisely match energy input, at low flow rates, to heat water to the required level.
-
more responsibility - The Rinnai Infinity VT has an improved minimum start-up flow rate, saving on water, and ensuring your Infinity is future proofed for water efficient tapware.
