RIWORY 85,000 BTU Tankless Propane Water Heater Specifications

Instant and Continuous Hot Water Performance

The RIWORY tankless gas water heater is designed to provide endless hot water on demand. Unlike tank heaters that can run out during peak usage, this system heats water only when needed, ensuring uninterrupted supply.

With a maximum flow rate of 3.6 GPM, the unit can comfortably support:

• One shower and one sink at the same time
• Two bathroom fixtures simultaneously
• Kitchen sink and bathroom sink together

This makes it ideal for small families, couples, or households where hot water demand is moderate but consistent.

High-Output 85,000 BTU Heating Power

At the core of this system is its 85,000 BTU heating capacity, which allows it to deliver hot water quickly and maintain stable temperatures even during colder seasons.

Key benefits of this output level include:

• Fast heating response
• Reliable winter performance
• Sufficient power for multiple fixtures
• Reduced temperature drop during simultaneous use

The system ensures that water reaches desired temperatures within seconds of activation.

4-Stage Energy-Saving Combustion Technology

One of the standout features of the RIWORY propane tankless water heater is its intelligent 4-stage energy-saving combustion technology. This advanced system adjusts the burner output in stages rather than operating at full power all the time.

Advantages of staged combustion include:

• Minimum heat load as low as 8,500 BTU
• Improved comfort during summer use without mixing cold water
• Adequate heating power during winter conditions
• Reduced propane consumption
• Enhanced energy efficiency

By dynamically adjusting heat output, the system balances comfort and efficiency throughout the year.

Intelligent Constant Temperature PLUS System

Temperature fluctuations are a common complaint with older gas water heaters, especially when multiple fixtures are in use. RIWORY addresses this issue with its Intelligent Constant Temperature PLUS system.

This system:

• Automatically adjusts the air-fuel ratio steplessly
• Maintains water temperature within ±1°F
• Prevents sudden temperature spikes or drops
• Enhances safety for children and elderly users

Even if another faucet is turned on unexpectedly, the water temperature remains stable, significantly reducing the risk of scalding.

Advanced Anti-Freeze Protection for Winter Use

Cold climates can pose serious risks to tankless water heaters. The RIWORY HO-Bas series gas instant water heater includes multiple anti-freeze protection systems to ensure safe operation during winter.

Anti-freeze features include:

• Four built-in heating modules rated at 25W each
• Automatic activation when temperatures fall below 39°F (4°C)
• Windproof device at the top air outlet to block cold air intrusion
• Protection of the heat exchanger and internal pipes

These features work together to prevent freezing damage and ensure reliable winter performance.

Pure Copper Heat Exchanger and Durability

The RIWORY gas tankless water heater uses a 100% pure copper heat exchanger, which plays a critical role in efficiency and longevity.

Benefits of the copper heat exchanger include:

• Thermal efficiency of up to 95%
• Excellent heat transfer performance
• Reduced heat loss
• Strong resistance to corrosion
• Service life of up to 5 years

This high-quality component ensures fast heating and long-term reliability under regular use.

Energy Efficiency and Cost Benefits

Because it heats water only when needed, the RIWORY propane tankless water heater avoids the standby energy losses associated with tank systems.

Energy-saving advantages include:

• Lower propane consumption
• Reduced operational costs
• Efficient combustion control
• Minimal wasted energy during idle periods

Over time, these efficiency gains can help offset the initial investment, especially for households with regular hot water usage.

Comprehensive Safety Protection Systems

Safety is a major priority for indoor gas appliances. The RIWORY tankless water heater gas model includes a wide range of built-in safety protections that work together to ensure secure operation.

Safety features include:

• Over-temperature protection
• Anti-dry combustion technology
• Water over-pressure protection
• Low water pressure starting protection
• Anti-scald protection
• Abnormal combustion flame protection
• Dual gas solenoid valve
• Automatic thermostatic system

These layered protections reduce the risk of malfunction and enhance peace of mind for daily use.
