Review RINNAI H735012 Genuine Oem Replacement Part

The Rinnai H73-501-2 is a high-performance tankless water heater designed for residential applications. This model is part of Rinnai's prestige series, known for their energy efficiency and advanced technology.

The H73-501-2 is a condensing tankless water heater, meaning it can extract more heat from the same amount of fuel compared to non-condensing models. It has a maximum input of 199,000 BTUs and can provide a continuous supply of hot water at a flow rate of up to 7.3 gallons per minute. This makes it suitable for larger homes with multiple bathrooms and high hot water demand.

This tankless water heater features an intuitive digital control panel, allowing for easy temperature adjustments and diagnostics. It also comes with an advanced recirculation system, which can save water and energy by keeping hot water in the pipes and reducing the need for long waits at the faucet.

The H73-501-2 is designed with a compact footprint, making it easy to install in tight spaces. It also features a direct-vent system, which allows for installation in areas without a chimney. The unit is constructed with a corrosion-resistant stainless steel heat exchanger and comes with a built-in condensate neutralizer to protect the system from acidic water.

Additionally, this model is Energy Star certified, meaning it meets or exceeds the energy efficiency guidelines set by the U.S. Environmental Protection Agency. It also comes with a 12-year heat exchanger warranty and a 5-year parts warranty, providing peace of mind for homeowners.

In summary, the Rinnai H73-501-2 is a powerful and energy-efficient tankless water heater suitable for larger homes with high hot water demand. Its advanced features, compact design, and long warranty make it a smart investment for homeowners looking to upgrade their water heating system.

The Rinnai H73-501-2 is a tankless water heater model that is known for its efficiency and continuous hot water supply. Here are some pros and cons to help you make an informed decision about purchasing this water heater:

Pros:

1. Endless Hot Water: As a tankless water heater, the Rinnai H73-501-2 provides an endless supply of hot water, eliminating the need to wait for a tank to refill.

2. Energy Efficient: Tankless water heaters, in general, are more energy-efficient compared to traditional tank water heaters as they only heat water when it is needed.

3. Compact Size: The Rinnai H73-501-2 has a compact size, making it an ideal choice for spaces where a traditional tank water heater would not fit.

4. Long Lifespan: Tankless water heaters have a longer lifespan compared to traditional tank water heaters, with an average lifespan of around 20 years.

5. Low Standby Loss: Since the water is not stored in a tank, there is no standby loss, which results in energy savings.

Cons:

1. Higher Upfront Cost: Tankless water heaters, including the Rinnai H73-501-2, have a higher upfront cost compared to traditional tank water heaters.

2. Requires Professional Installation: Due to the complexity of the system, professional installation is required, which can add to the overall cost.

3. May Not Be Suitable for Large Families: While the Rinnai H73-501-2 can supply a constant stream of hot water, it may not be able to keep up with the hot water demands of larger families.

4. Potential for Higher Energy Bills: While tankless water heaters are energy-efficient, they can result in higher energy bills due to their constant energy usage.

5. Potential for Mineral Build-Up: Hard water can cause mineral build-up in the heat exchanger, which can reduce the efficiency of the water heater over time.

In conclusion, the Rinnai H73-501-2 is an excellent choice for those who want an endless supply of hot water, a compact size, and energy efficiency. However, it comes with a higher upfront cost, requires professional installation, and may not be suitable for larger families or those with hard water.

If you are considering purchasing the Rinnai H73-501-2, it is recommended that you carefully consider your hot water usage needs, the size of your family, and the cost of professional installation before making a decision. Additionally, if you have hard water, you may want to consider investing in a water softener to prevent mineral build-up and maintain the efficiency of the water heater.
