The Rinnai N Series 30% Hydrogen blend ready water Heaters utilise market leading patented technology to deliver cutting edge efficiencies and performance. Stainless-Steel Primary Heat Exchanger increasing durability and providing market leading warranties (Up to 7 years)

Advanced condensing heat exchangers combined with innovative down firing pre-mix burner technology ensures every cubic metre of natural gas or LPG is utilised to the maximum.


The N Series can deliver high volumes of temperature accurate hot water. Rinnai Water Heaters can deliver hot water at accuracy level which is + / - 1˚C of the heater set point. The N1600 can produce up to 37 litres per minute and there is also an additional flow booster setting within the N Series which can allow even higher volumes if the right conditions are met (dynamic water pressure of over 3 bar and water heater set to 40 or below).

With the powerful fan motor, the N Series can also achieve flue runs of up to 46 meters utilising the Rinnai concentric 80/125 flue run but can also be utilised in a common flue arrangement.

The N1600 weighs in at 29kg. The appliances can be wall mounted but if wall space is not available, they can also be installed on a cascade frame. The result of this kind of flexibility when it comes to installation means these water heaters can be used for any type of application however big or small. Some examples of applications of these would be but not limited to Bars, Restaurants, Gyms, Healthcare, Hotels, Process, Brewing, Food Production and Farming.

Rinnai Water Heaters react to demand and modulate accordingly, because of this they can produce savings both on a monetary and emission level. With Rinnai hot water solutions there is no storage within the water heaters themselves therefore there is no heat loss.


All Rinnai water heaters are designed to the standard EN26 which means a lot of safety features are built into the appliance. An example of these measure would be the water temperature safety shut off and exhaust temperature sensor. The water temperature safety shut off will shut down the water heater if the water temperature leaving the appliance increased to 3 degrees of what it was set too. The exhaust temperature sensor would also shut of the appliance if the exhaust gases were too hot. This is especially important given the fact that most condensing flues are made from plastic and if the exhaust temperature rose too high the flue could melt.

The units are renewables-ready and suitable for use as a temperature booster for solar thermal and heat-pump installations.

The Rinnai 1600i Condensing LPG Gas Water Heater is also future-proofed against regulatory and legislative changes.

*Please note this water heater includes an easy to fit LPG conversion kit, allowing you to seamlessly switch between natural gas and liquid petroleum gas for uninterrupted hot water.
