Novieex Propane vs Electric Specs
Fuel type
The Novieex 3.6 GPM Propane Tankless Water Heater uses propane gas as its energy source. It requires a gas inlet with NPT 1/2" fittings and a gas rated pressure of 11.24" w.c. (2.8 kPa). In contrast, the NOVIEEX 13kW 240V Electric Tankless Water Heater runs on electricity. It needs a 240V power supply, a 60A double-pole circuit breaker, and 6 AWG wires. You must choose based on your home's existing infrastructure. If you have natural gas or propane lines, the gas model is ready to go. If you have a robust electrical panel, the electric unit is the better fit.
Voltage and power
Power delivery differs significantly between these two units. The propane model operates on 110V-120V AC/60Hz for its controls but uses 86,000 BTU of gas power for heating. The electric model draws 240V and delivers 13kW of heating power. The electric unit requires a higher amperage setup, specifically a 60A circuit, which is standard for high-output electric tankless heaters. The propane unit uses lower voltage for its electronics. You need to verify your electrical capacity if choosing the electric version, as it demands a dedicated high-amperage line. The propane unit relies on gas pressure rather than high-voltage electrical draws for its primary heating function.
Temperature range
Both heaters offer precise digital temperature control, but their ranges vary. The Novieex 3.6 GPM Propane Tankless Water Heater allows adjustments from 95°F to 149°F with ±1°F precision. This wider upper range can be useful in very cold climates or for high-demand appliances. The NOVIEEX 13kW 240V Electric Tankless Water Heater adjusts from 77°F to 140°F in exact 1°F increments. While the electric model starts at a lower minimum, the propane unit reaches higher maximum temperatures. You should select the propane model if you need water hotter than 140°F. Otherwise, both provide stable control to prevent scalding or chilling during use.
Dimensions and build
Size and weight vary between the two models. The propane heater measures 28.5 x 17.3 x 10.8 inches and weighs 19.8 pounds. It is a larger, boxier unit. The electric model is much more compact, measuring 15.86" H x 11.14" W x 3.18" D. It is ultra-slim, designed to save space in tight closets or utility rooms. The electric unit saves over 80% more space than traditional tanks, and its slim profile is more discreet. If space is limited, the electric model is the clear winner. The propane unit requires more wall space and depth due to its internal gas components and burner system.
Safety systems
Both units include comprehensive safety features for indoor installation. The propane heater features a multi-protection system guarding against gas leaks, overheating, dry-firing, and freeze damage. It also includes an LED touchscreen interface for monitoring. The electric model boasts an 8-layer safety system. This includes water and electricity isolation, dry-combustion prevention, over-temperature cutoff, over-pressure relief, leakage protection, grounding protection, IPX4 waterproofing, and smart fault self-diagnosis. The electric unit offers more distinct electrical isolation layers. However, the propane unit specifically addresses gas leak detection, which is critical for its fuel type. Both ensure safe operation for families.
