Operations at temperatures above 65°C

Rheem commercial gas models 621 265, 631 265, 621 275, 631 275 are designed to operate at temperatures up to 82°C for sanitising and other applications.

Where the water supplied by the water heater is required consistently at any temperature above 80°C, we strongly recommend you use a pumped recirculation system. (Please refer to the Equa-Flow® section.)

Gas pipe supply

The gas supply piping should be sized in accordance with AS/NZS5601.1.

The gas supply pipe must be sized so that the minimum gas pressure is available at the inlet to each water heater when all appliances are operating at maximum gas consumption.

The minimum gas pressures is 1.13 kPa for natural gas.

Approximate daily energy consumption

These daily gas consumption figures are approximate. They’re based on:

  • A daily usage of hot water per water heater in litres, at 50°C rise
  • Using natural gas, but they can be used with reasonable accuracy for other gas types
  • Mains pressure supply systems only

The figures do not allow for pipe heat losses. An additional allowance must be made for large manifold systems and installations designed with a circulated flow and return system.

Use the table to calculate

  • The approximate energy cost for a particular installation
  • The average daily hot water consumption when the energy consumption is known
