Do You Need Electric for Tankless Water Heater Propane?

While propane tankless water heaters do not require electricity to heat water, they do need a small amount of electricity to power the control panel and ignition system. This is in contrast to electric tankless water heaters, which require a significant amount of electricity to heat water and are not recommended for areas with low incoming water temperatures or high demand.

Propane Tankless Water Heater Specifications

Propane tankless water heaters typically have the following technical specifications:

Specification Typical Range
Flow Rate 2-12 GPM
Temperature Rise 35-80°F
Fuel Type Propane
Electrical Requirement 120V, 1-2 Amps

The higher flow rate and temperature rise of propane tankless water heaters make them better suited for colder climates or larger homes with higher hot water demand. However, they do require proper venting to the outside, which can add to the installation cost.

Electrical Requirements for Propane Tankless Water Heaters

While propane tankless water heaters do not require a significant amount of electricity to operate, they do need a small amount to power the control panel and ignition system. Typically, these units require a 120V, 1-2 Amp electrical connection.

The control panel is responsible for monitoring and regulating the water temperature, flow rate, and gas input. The ignition system is responsible for lighting the burner when hot water is needed. Without electricity, these critical components would not function, and the water heater would not be able to operate.

It’s important to note that the electrical requirements for propane tankless water heaters are much lower than those for electric tankless water heaters, which can require up to 240V, 40-60 Amp electrical service.

Considerations for DIY Installation

For those considering a DIY installation of a propane tankless water heater, there are several important factors to consider:

  1. Proper Sizing: Ensure that the tankless water heater is properly sized for the home’s hot water demand. This may involve hiring a professional to perform a heat loss calculation and determine the appropriate unit size.

  2. Gas and Venting Requirements: Propane tankless water heaters require proper gas and venting lines to be installed. This may involve running new gas lines or installing a dedicated venting system to the outside.

  3. Local Building Codes: Always check with local building codes and authorities to ensure that the installation meets all necessary requirements. This may include obtaining permits, inspections, and following specific installation guidelines.

  4. Safety Considerations: Proper installation and maintenance of a propane tankless water heater are crucial for safety. Ensure that the unit is installed in a well-ventilated area, and follow all manufacturer’s instructions for safe operation.

Advantages of Propane Tankless Water Heaters

Propane tankless water heaters offer several advantages over electric models, including:

  1. Higher Flow Rates and Temperature Rise: Propane tankless water heaters typically have higher flow rates and temperature rise capabilities, making them better suited for colder climates or larger homes.

  2. Energy Efficiency: Propane is generally a more energy-efficient fuel than electricity, which can result in lower operating costs for the homeowner.

  3. Continuous Hot Water: Tankless water heaters, regardless of fuel type, provide continuous hot water on demand, eliminating the need for a storage tank.

  4. Compact Size: Propane tankless water heaters are typically smaller and more compact than traditional tank-style water heaters, making them easier to install in tight spaces.

Conclusion

In summary, while propane tankless water heaters do require a small amount of electricity to power the control panel and ignition system, they are generally more suitable for colder climates and larger homes than electric models. When considering a DIY installation, it is important to properly size the unit, follow local building codes, and ensure safe operation. By understanding the technical specifications and electrical requirements of propane tankless water heaters, homeowners can make an informed decision on the best water heating solution for their home.
