Gas Hot Water Systems

Rinnai INFINITY

Rinnai INFINITY Gas Water Heater

The Rinnai INFINITY at its functional core, is a powerful energy-efficient gas water heater that is suitable for both residential households and heavy duty commecial use.

Designed with innovative technology and the environment in mind, the Rinnai INFINITY features a superior energy-efficient tankless system, as it only heats water that flows through the unit, delivering fast and instantaneous hot water whenever it is needed. In turn, your running costs and greenhouse gas emissions are reduced significantly. And unlike storage water heaters which will eventually run out of hot water, the Rinnai INFINITY will never run out of hot water when there is multiple usage within a household or a building.

Advantages

Advantages of Super High-Efficiency INFINITY

Fast and Continuous Hot Water Flow

Water is not stored but enters inlet pipe and gets heated via a direct fired heat exchanger only when hot water is required, generating an instantaneous and unlimited flow of hot water.

Compared to a Standard Tank: During times of heavy usage, a traditional storage tank water can be depleted, causing delays in hot water supply.

Save Energy and Running Costs

Rinnai tankless system heats water only when it is needed, sensing the demand no matter how many appliances are in use at the same time, turns off when it is not in use, resulting in less wasted energy, and saving significantly on your energy bills.

Compared to a Standard Tank: Storage tank requires water to be heated and reheated to maintain desired set temperature regardless of usage or demand, resulting in a waste of energy.

Space Saving Compact Design

Our heaters are wall-mounted and the size of a suitcase, taking up less space for heating. The extra room space from the original system can make way for other services and equipment.

Compared to a Standard Tank: Traditional large tank requires more installation space and management.

Longer Lifespan

A Rinnai INFINITY Water Heater has up to twice the lifespan of a traditional water tank and requires low maintenance, the cleaning of gas heater filters and priming of pump are only required for quarterly inspection. You will have more confidence in maintaining a Rinnai INFINITY than a traditional storage heater.

Compared to a Standard Tank: Last longer in years and lower maintenance required.

Structural Loading

This system significantly reduces the load on structure which will translate to lower cost in reinforcing the concrete and steel structure.

Computer-based Electronic Ignition and Control System

Heater will adjust flame output and its water flow rate as needed to ensure a temperature set point is maintained.

Flexibility for Future Expansion

Easy modification by adding extra gas heaters if a higher capacity is required for future expansion.

Advanced Systems

Rinnai Advanced Hot Water Systems

Rinnai Tank-less Gas Water Heater Systems are in better demand these days due to its energy efficiency and space saving advantage. Commercial water heating demands higher flow rates than a single Rinnai INFINITY unit can provide at any one time, this is where our advanced hot water systems come into place. The Rinnai INFINITY gas water heater can be designed into a varied of hot water system solutions according to the demand, internal piping designs, and buildup of a vicinity. Our advanced systems include Manifolds Pack, Demand Duo, as well as Hybrid Hot Water System that combines with solar energy.

Manifold Pack

Rinnai Manifold Pack consists of a minimum of 2 INFINITY heavy duty water heaters plumbed together. It is designed as a staging system, so that only the required number of heaters start to match the desired hot water flow rate. Designed specially to compliment the Rinnai INFINITY heavy duty, the PAM (Pressure Activated Manifold) Valve System ensures that the units ignite in sequence, as the valve cannot open at flows less than required to operate one water heater. When it comes to installation considerations, Rinnai Manifold Pack hot water system can save up to 70% of space as compared to a boiler system used by many commercial operations.

Suitable applications: Manufacturing plants, processing industries, convention centers, hotels, hostels, commercial kitchens, commercial laundries, gyms, malls, cafes and restaurants.

Demand Duo

Rinnai Demand Duo combines between 1 to 6 INFINITY heavy duty water heaters with a storage tank that allows a short period of high hot water flow rate, and you will get greater results of the Manifold Pack. Demand Duo is a complete packaged storage hot water system made up of one or more heavy duty water heaters with a manifold system, primary pumps, thermostat and a stainless-steel tank that holds 250 to 315 litres (or 1,000 litres, depends on situation) of hot water per system. Installations of this type typically have a predictable hot water volume, usually based on a high peak volume of people living in a particular building either showering, washing or eating, or industrial machines that require regular peaks of water. Rinnai Demand Duo systems can also be used instead of the Manifold Pack for projects where limited gas supply is available.

Suitable applications: Manufacturing plants, processing industries, hotels, apartment blocks, student accommodation, commercial kitchens and commercial laundries.
