Rinnai Infinity EF250 External

 

A new generation of continuous flow water heater
Temperature controlled continuous flow gas hot water system for external applications. Factory preset to 55 °C.

• High efficiency (95%)
• Lower gas emissions (due to a secondary heat exchanger)
• Subsequent savings (water is preheated so doesn't use as much energy)



 

Energy cost saving references 

1.  The calculations are based on independent energy consumption data from AS 4232 and heat loss data derived from the BRANZ HEEP program. Comparative electric cylinder was 180 L in capacity.

2.  60% Saving is for the Rinnai INFINITY® gas water heater VT models running on Natural Gas. Rinnai Rinnai INFINITY® gas water heater VT models manufactured after July 2011.

3.  15% Saving is for the Rinnai INFINITY® gas water heater VT models running on LPG. Rinnai Rinnai INFINITY® gas water heater VT models manufactured after July 2011.

4.  66% Saving is for the Rinnai INFINITY® gas water heater EF250, EFi250, and EF24 models running on Natural Gas.

5.  28% Saving is for the Rinnai INFINITY® gas water heater EF250, EFi250, and EF24 models running on LPG.
