Rinnai INFINITY HD units are higher capacity gas continuous flow water heaters for applications where higher flow rates and higher temperatures are needed. 

The HD200 external has an inbuilt status monitor, which has an added feature of displaying an LC (00) error code when the unit requires cleaning (due to scale build-up).

Two models to choose from:

  • HD200 external unit with status monitor
  • HDi200 internal unit

Ignition system

Direct electronic ignition

Exhaust system
  • External unit - forced flue
  • Internal unit - room sealed forced flue
Frost protection

Fitted as standard. Frost protection operates automatically, as long as the appliance is connected to the electrical power supply, by activating when the temperature inside the unit drops below 3.5 °C, and turns off once the temperature inside the unit reaches 7 °C.

HDi200 1.00, 1.70 0.75, 1.15
Ingress protection rating

IPX4

Line pressure (min.)

NG - 1.13kPa, LPG - 2.75 kPa

Line pressure (max.)

3.5 kPa (maximum standing pressure under abnormal intermittent conditions is 5.0 kPa).

In the case of commercial metering, (i.e. 35-37 kPa coming in), there may be a requirement to regulate the incoming pressure down.

Noise level

59 dB(A). Some people are susceptible to low level noise. This needs to be considered if locating an appliance near a bedroom.

NOx af

less than 60 ppm

Power consumption
  • HD200, normal 48 W (NG), 60 W (LPG), automatic frost protection 100 W
  • HDi200, normal 64 W (NG), 67 W (LPG), automatic frost protection 100 W

Both units have a standby of 2 W

Pressure relief

Valve opens at 2060 kPa, closes at 1470 kPa

Safety devices
  • Flame failure
  • Boil-dry protection
  • Overheat protection
  • Fusible link
  • Pressure relief valve
  • Combustion fan RPM check
Water supply

Nominal operating pressure: 

  • HD200: 130-1000 kPa
  • HDi200: 140-1000 kPa

Activation flow rate: 2.4 litres per minute

Please note: If the water inlet pressure or flow rate drops below the minimum values stated above, operation of the INFINITY is not guaranteed. The unit requires both minimum flow rate and pressure to operate correctly.
