Leaders in continuous flow When you turn on a tap, you want water at the right temperature fast. Which is why, over the years, we’ve devoted considerable time and resource to leading edge research and development. We were the first to introduce continuous flow technology, and have been tirelessly working on improving this ever since. Our commitment to bring you the latest in technology has resulted in the next generation of water heaters.
What is continuous flow? It is exactly that—a continuous flow hot water system. Unlike storage tanks that can run out, continuous flow units deliver a pre-determined flow rate every minute for as long as the unit is running.

Model selection - domestic applications When specifying residential hot water applications there are some basic questions that you need to ask in order to correctly design a system. You also need to bear in mind future requirements of the building. The key point is water heating solutions should be designed to the number of outlets and not people.
Product selector - domestic applications Your budget, size of house, number of outlets, and hot water requirements all factor in determining the right continuous flow hot water system for your home. Use the product selector below to work out which model is right for you. 1. Determine the hot water outlets that will run simultaneously in your house, and list the flow rates against them.
Rinnai Infinity digital water controllers With a Rinnai Infinity digital controller, you choose your own personalised settings. Just select the water temperature you want (37-55 °C) in up to four different locations. This means you can set water at a safe temperature in the bathroom (a great safety feature), then set it higher, if you wish, in the kitchen and laundry.
Specifying commercial solutions Rinnai Infinity HD/EF units, manifolded units ( joined together), Demand Direct, Demand Duo, and Demand Rapid can provide all the hot water for large demand applications such as sports clubs, restaurants, motels, and apartment projects. For full details on Rinnai’s Demand solutions, please refer to the Commercial Water Heating catalogue available on our website www.rinnai.co.nz/waterheating_ brochures.html.
Designing central water heating systems Performance of Rinnai continuous flow units are directly related to hours of use and how well they are maintained. It is important when designing central water heating systems that they are sized correctly. This will extend the life of the system and reduce ongoing maintenance and servicing costs. Design principles 1. The Rinnai system should be regarded as a continuous flow system with storage back-up.
Fault indication In multiple unit installations it is important to know if a water heater is faulting. If a water heater is faulting this increases the wear and tear on the water heaters and will cause progressive reduction in the hot water supply if more units fail. Rinnai HD/EF water heaters can be fitted with a Rinnai HD Error Indication Switch (part R1070), volt free contact, which will close to indicate a water heater is not operating.
Manifold electronic control system (MECS) Infinity units can be manifolded together (up to 25) by connecting them in parallel to enable a greater hot water flow rate than is possible with a single unit. MECS is a totally integrated system, unique to Rinnai, that links each Infinity unit in the system and will turn on each unit as required. The system is designed to ensure gas is not wasted and that an endless supply of hot water is always available.
Circulating ring mains with Rinnai Infinities Hot water immediately when you turn on the tap—circulating ring mains give hot water instantly at all outlets. High temperature circulating ring main Notes on circulating systems with Infinity water heaters REUMSBMB (MECS master slave kit) Cylinder volume should be > 10 x the pipe volume between the Rinnai water heater and cylinder. Temper outlets as required with point-of-use tempering valves.
Positioning continuous flow units In order to provide safe and effective water heating it is important to adhere to all relevant gas installation standards. Prior to purchasing or siting an appliance check the guidelines detailed in this section. Internal models Internal models are designed for indoor installations only. They may be installed in an enclosure if the requirements of AS/NZS 5601.1 are satisfied.
General flue clearances - external models The following diagram has been provided to assist in determining where, and if an external continuous flow water heater can be installed. If in doubt, consult a licensed gasfitter who will have access to 'Minimum clearances required for balanced flue terminals, fan-assisted flue terminals, room-sealed appliance terminals and openings of outdoor appliances' from AS/NZS 5601.1 (p. 94-95).

Appendix 3: Commercial sizing guidelines Sizing guidelines for commercial applications when using secondary storage tanks The table below, based on industry experience, provides average hot water demand for various applications.
Appendix 4: LPG gas bottle consumption We often get asked about how long a gas bottle will last when running a gas appliance. Using the calculation below you can work this out yourself. LPG gas bottle energy calculation 1 kg of LPG gas contains 50.4 MJ of energy 1 kW = 3.6 MJ This means that a 45 kg LPG gas bottle has: 45 kg x 50.4 MJ = 2268 MJ This works for the different bottle sizes, here are the most common: 9 kg = 453.
Appendix 5: Gas boosted solar In New Zealand, solar systems will need boosting unless you are willing to run out of hot water. A gas boosted system is best because it only works when you need hot water that your solar system can't supply. How a gas boosted system works 1. The sun's rays heat water in the solar panels for free. 2. Hot water from the panels is stored in the tank. 3. If the water is too cold, the Rinnai Infinity gas booster heats the water on demand as it travels from the tank to your tap.
