Instantaneous electric water heaters coming soon

Rinnai’s new range of instantaneous electric water heaters are suitable for all commercial and domestic applications that require decarbonising technology capable of delivering domestic hot water (DHW) needs.


Rinnai instantaneous electric water heaters

Rinnai’s approach to producing decarbonising technology has resulted in a DHW electric water heater that has been designed to offer direct heating capability. The technologically advanced bare wiring technology rests in the water enabling the system to achieve the pre-set water temperature quickly and accurately. The electric on demand water heaters are lightweight at less than 4kg, and diminutive (450 x 235 x 94).


The KW rating within the range is scalable with a choice of 21kW, 24kW and 27kW, ensuring suitability for a wide variety of applications. A compact design allows for easy installation and is proven to increase energy efficiency and therefore reducing operational costs. Ease of installation and handling are a major feature.


Rinnai’s instantaneous on demand electric water heater range can maintain a temperature range from between 20°C and 60°C, which is adjustable digitally in 0.5°C increments. All units can also accept preheated water.


Other features of the range include:

·      Overheat protection

·      Multi-functionable display

·      Full electric control

·      Rapid heat up capability

·      Quick reaction to sudden shifts in grid capacity output

·      Solar compatible.


All models have LCD screens that provide visual information on current water temperature, operational performance and Eco Mode – which supplies confirmation of the appliance operating economically and therefore reducing unnecessary energy wastage and costs.


Rinnai’s instantaneous electric water heater has a renewable system operation setting that recognises incoming water temperatures more than 30°C, then applies only the correct amount of energy to achieve the required temperature uplift making them an ideal solution to use with solar thermal and renewable systems.
