Infinity HD70e - 69kW Commercial Water Heater
Rinnai Heavy Duty 70e External Commercial Water Heater
The Rinnai HD70e external commercial water heater has the added advantage that the unit is externally mounted. This feature gives greater flexibility at the design stage and can offer an alternative solution where flue runs are problematic or internal space is not available.
As with all units in the Rinnai heavy duty range the HD70e has frost protection.
A range of external ancillary items including a pipe cover box and security cage are available where necessary.
Capable of flow rates of up to 979 litres per hour at a 50°C rise, the HD70e is suitable for installation on a secondary return.
Ideal for commercial, industrial and large domestic installations.
Rinnai commercial water heaters are available in both Natural Gas and LPG

HD70e as a Solar Booster
The HD70e will deliver 12.6 l/min @ 50˚C Rise using 5.02m³ gas. If we increase the incoming water temperature we get the following saving:
|Flow rate||Energy||Saving on gas|
|12.6l/min @ 40°C Rise||35.1kW||21% (1.05m3)|
|12.6l/min @ 30°C Rise||26.4kW||40% (2.0m3)|
|12.6l/min @ 20°C Rise||17.6kW||61% (3.1m3)|
|12.6l/min @ 10°C Rise||8.8kW||81% (4.1m3)|
A 20 tube panel will yield approx 1439kW/yr* so a fairly standard arrangement of 3 panels would yield 4317kWh/yr
Consequently this equates to 4317kW free energy or the equivalent of 401.6 m³ gas per annum
