Hour Delivery Capacity

One of the aspects that truly set the Rinnai GHF4135 apart is its superior first-hour delivery capacity. This system is capable of delivering up to 257 litres of hot water in the first hour, surpassing the standard capacity by a notable margin. This capacity guarantees a steady hot water supply, even during peak times, and allows it to deliver generous amounts.

Natural and Propane Gas Options

In terms of fuel source compatibility, the Rinnai GHF4135 offers versatile installation options by being compatible with both common gas types, LPG and Natural Gas. You have the option to select from the available lp gas models - natural or propane - that aligns with your preferences and requirements.

This dual gas optionality ensures that the Rinnai GHF4135 can adapt to different energy sources, providing flexibility during installation.

Safety Temperature Shut-off

Safety is a paramount consideration when dealing with hot water systems. The Rinnai GHF4135 doesn’t compromise on this aspect. It features a propane gas thermostatically controlled system with a safety temperature shut-off, providing an essential safety measure for users. Moreover, the device is thermostatically controlled with safety, ensuring optimal performance and peace of mind.

The system automatically turns off when the water temperature hits a certain point, averting overheating and potential mishaps. This controlled with safety temperature feature ensures the safe operation of the system and provides peace of mind, knowing that you and your family are protected from potential hot water incidents.

Enhancing Durability and Performance

The design of the Rinnai GHF4135 prioritizes durability and performance. This is evident in the inclusion of a vitreous enamel lined steel tank, inbuilt anode protection, and a pressure temperature relief valve, all of which contribute to the system’s longevity and superior performance.

The enamel lining acts as a barrier between the steel and water, offering superior protection against corrosion - a crucial factor in extending the tank’s lifespan. The enamel, fused to the steel at high temperatures, creates a durable and impermeable surface that resists cracks, scratches, and rust, and withstands high temperatures, contributing to the tank’s longevity and leak prevention. With an 8-year warranty on the internal cylinder of the GHF4135, Rinnai reflects its confidence in the unit’s long-term performance and energy efficiency.

Vitreous Enamel Lined Steel Tank

At the heart of the Rinnai GHF4135’s durability is its vitreous enamel lined steel tank. Vitreous enamel lining consists of glass-like materials known as frits, which are ground into fine particles and melted onto the steel surface to create a strong, inseparable coating. This coating, serving as a protective barrier between steel and water, greatly minimizes corrosion, thus prolonging the tank’s lifespan.

The robust enamel lining, resistant to cracks and scratches, withstands high temperatures, preventing leaks and ensuring reliable, long-lasting operation.

Inbuilt Anode Protection

The Rinnai GHF4135 comes with an inbuilt anode protection feature that plays a crucial role in maintaining the system’s durability. This sacrificial anode, typically made of magnesium or aluminum, functions through an electrochemical process known as electrochemical protection.

The anode material corrodes preferentially to the water heater’s steel tank, thereby protecting it from corrosion. This process significantly extends the lifespan of the tank, as it attracts corrosive elements in the water to itself, corroding in place of the tank.

The durability inbuilt anode protection reduces maintenance by preventing tank corrosion.

Pressure Temperature Relief Valve

A key feature of the Rinnai GHF4135 is its pressure temperature relief valve, a critical safety feature that ensures the system operates within its rated capacity during temperature rise. The relief valve is designed to open at a set point, usually around 210 degrees Fahrenheit or 150 psi, ensuring safe operation of the water heater within its rated capacity.

If the temperature or pressure exceeds the limit, the valve discharges water to restore the system to safe operating conditions. This feature not only ensures the system’s longevity but also provides added peace of mind for homeowners, knowing that their hot water system is equipped with safety measures that guard against potential issues.

Standard installation includes removal of the old water heater and connection to existing plumbing, assuming the new unit is installed in the same location. However, additional installation costs may be incurred for tasks such as lifting the unit, installing recess boxes, making building modifications, or electrical upgrades. It’s advised to have an upfront agreement on prices for these extra services to avoid any unexpected costs.

Comparing the Rinnai GHF4135 to Other Hot Water Systems

Despite the multitude of features and benefits the Rinnai GHF4135 offers, it’s worth comparing it with other hot water systems on the market. This system offers energy efficiency and capacity advantages over some competitor brands, while lacking advanced features found in others.

As part of the Hotflo range, the Rinnai GHF4135 is notable for energy savings and affordability in terms of installation costs. However, competitor brands like Rheem Stellar 330 and Aquamax G270SS may lead to greater long-term savings through their superior energy-efficient performance and larger capacity.

This makes it a competitive option within the Hotflo range and a viable choice for homeowners looking for a reliable and efficient hot water system.

Competitor Brands

Competitor brands like Rheem and Dux offer alternative options with varying features and benefits. For example, Rheem offers the Stellar 330 with distinct features including a larger capacity and a 5-star energy rating, indicating a focus on efficiency and capacity in their products.

Nonetheless, the Rinnai GHF4135, boasting an impressive energy rating, quick recovery system, and durable design, stands strong against these competitors. While Rheem is recognized for its reputable manufacturing and reliable products, the Rinnai GHF4135’s unique features and competitive pricing make it a strong contender in the hot water system market.


In conclusion, the Rinnai GHF4135 135L Gas Hot Water System proves to be a high-efficiency, versatile, and safe solution for various homes. Featuring a superior first-hour delivery capacity, flexible installation options, and a suite of safety features, it certainly stands out in the market.
