Rinnai hot water – instant, continuous, limitless and sensibly economic

Installers, specifiers and end users’ installers have the most practical and economically viable solution for all domestic and commercial hot water heating and delivery needs in Rinnai’s comprehensive range of energy efficient A rated, electronically controlled continuous flow gas fired units and systems.

The natural gas or LPG water heaters guarantee a limitless supply of accurately temperature controlled safe and useable hot water, time after time after time to any type or size of site or application. The Rinnai range delivers energy saving performance and low greenhouse emissions through new low NOx burner technology.

All units and systems can be installed as stand-alone or manifolded to provide unlimited hot water for the largest of all commercial sites such as big hotels, busy gyms, high rise offices etc.

Water temperature is and can be pre-set through easy-to-use built in digital controls, eliminating the risk of scalding and potentially eradicating the need for thermostatic mixing valves. Water can be used simultaneously at several points of delivery with no fluctuation of temperature. The newly updated Rinnai Infinity range is designed for use directly off the mains, with no need for large, ungainly and energy inefficient storage vessels.

For example, Rinnai’s Infinity 16i continuous flow water heater is designed to meet the hot water needs of domestic and light commercial applications. The Infinity 16i, weighing just 18kg and measuring less than 675mm (H) x 139mm (W), has a delivery capacity of 15.2 litres per minute, at a temperature rise of 25°.

Rinnai Heavy Duty water heaters are high efficiency gas continuous flow water heaters with outputs up to 69kW. The Rinnai Heavy Duty HD50i Internal water heater is a wall hung, gas fired, continuous flow water heater capable of producing hot water at 770 litres per hour at a 50°C rise. The HD50i has a 125mm concentric flue which can be extended up to 15m, less 1m per 45° bend.

Compact and reliable, the HD50i operates between 1-10 bar pressure, which is suitable for mains and systems with boost pumps. Incoming water temperatures in excess of 60°C are accepted, making the HD50i suitable for secondary return systems. Water can be delivered at high volume with minimum gas consumption. All models have full electronic ignition with no pilot light and operate on demand only, consuming no gas when not in use.

All Rinnai internal HDC condensing continuous flow water heaters, are room-sealed, power flue appliances while the external weatherproof models have forced exhaust which enables them to be compact, saving both floor and wall space.

Rinnai’s unique condensing technology incorporates two heat exchangers to achieve optimum water heating generated from every cubic metre of Natural Gas or LPG. The condensing process delivers up to 95% thermal efficiency, which translates to significant energy savings when compared to standard on-demand water heaters or conventional stored systems.

For applications where the use of stored hot water cannot be avoided, i.e. in refurbishments where there may be a constraint on the amount of gas available, usually through the gas main size, Rinnai’s ‘pack’ system covers this shortfall by fitting a small amount of storage capacity.

Rinnai Gas Hot Water Storage Pack represents the best value-for-money solution on the market today with everything delivered direct to site in one complete package

The pack consists of up to five heavy duty water heaters with an equal number of flue kits (for internal heaters) or an equal number of pipe cover boxes (for external models) and sufficient valve packs. Also included is one hot water storage vessel (stainless steel 300L, 500L or 800L glass lined steel) along with necessary valves and one primary pump with valves and one unvented kit. Add to this an expansion vessel of either 50L or 80L capacity, and all relevant valves. Common header flue systems are also available to further stream line the installation.

Typical applications for the commercial ranges include cafés, nurseries, factories and offices, laundries, hotels and restaurants, sports clubs, shower blocks in caravan parks – and many more.

Rinnai has also embraced renewables in the form of the Rinnai Booster, which, it claims, is the most energy efficient boosting solution on the market today. The water heater maximises solar gain, as it only functions and consumes energy when more hot water is needed to boost the solar gain, meaning that the true impact of solar is being achieved. The rest of the time the unit is inactive.

Rinnai continuous flow hot water systems deliver on all levels in a cost effective and practical manner. Easy to install and operate the units provide a flexible and energy efficient solution for domestic applications and for all sectors of business and industry.
