Tankless Water Heater Propane Gas, 16L Instant Hot Water Heater with Fahrenheit Digital Display, Indoor Installation Up to 4.22GPM, 109188BTU

INSTANT HOT WATER ON-DEMAND: Boasting 109,188BTU (32KW) propane gas input, this on-demand tankless water heater delivers 16L/min (4.22GPM) flow rate with 25°C temperature rise—no preheating required. The instant-on design eliminates wait times, providing hot water within seconds for indoor showers, kitchen chores, or garage projects. Say goodbye to preheating delay of storage water heater.

INDUSTRIAL-GRADE MATERIALS: Constructed with high quality metal housing and UL-certified Category II stainless steel vent pipe (requires 3° downward slope to prevent condensate erosion), this propane tankless water heater withstands indoor humidity and acidic gas combustion byproducts. The tankless design minimizes limescale buildup, while the rust-resistant heat exchanger ensures long-term unclogged operation for stable thermal output.

FAHRENHEIT/CELSIUS DIGITAL DISPLAY: Equipped with a dual-unit digital display, easily switch between Fahrenheit (86°F-131°F) and Celsius (30°C-55°C) by pressing the mode button. Precision temperature control allows real-time monitoring, while the automatic overheat warning activates at 125°F (52°C) to prevent scalds. Ideal for households with children or elderly, presetting below 120°F (49°C) balances safety and comfort—perfect for this propane tankless water heater's versatile indoor use.

MULTI-LAYER SAFETY SYSTEM FOR RELIABLE OPERATION: Features include overheat protection (activates at 125°F), and gas leak detection that cuts off energy supply during anomalies. The fan continues running post-shutdown to cool internal components, while the 40-minute timer prevents dry burning—extending the lifespan of this propane tankless water heater indoor.

ROFESSIONAL INDOOR INSTALLATION REQUIRED: Indoor installation must be performed by qualified technicians due to complex gas piping, venting, and electrical connections. Improper setup risks gas leaks, CO poisoning, or equipment failure. Key specs: 110V power, 4.22GPM max flow, and compatibility with propane gas only—ensure compliance with local codes for safe operation of this on demand water heater.
