Introduction to Tankless Hot Water Heaters

Tankless hot water heaters, also known as on-demand water heaters, provide hot water only as it is needed. Unlike traditional tanks that store and continuously heat water, tankless units heat water directly through a heat exchanger, ensuring you never run out of hot water while also reducing energy consumption and costs.

Benefits of Tankless Hot Water Heaters

  • Energy Efficiency: By heating water on demand, these units can be 24%–34% more energy efficient than traditional water heaters for homes that use 41 gallons or less of hot water daily.
  • Longevity: Tankless water heaters typically last longer than traditional tank heaters, with life expectancies of more than 20 years compared to 10-15 years for tank models.
  • Space Saving: These units are compact and can be mounted on a wall, freeing up floor space in your home.
  • Continuous Hot Water Supply: Ideal for families and high-demand usage, ensuring hot water is always available without waiting for a tank to refill.

Signs Your Tankless Water Heater Needs Attention and How ROMA Can Help

Tankless water heaters are known for their efficiency and convenience, but like any appliance, they can develop issues over time.

Here are some common indicators that your tankless system may need professional attention, along with how ROMA Heating & Cooling can assist:

1. Fluctuating Water Temperatures

  • How ROMA Can Help: We can inspect and repair or replace the flow sensor and ensure all internal mechanisms are functioning correctly.

3. Decreased Water Flow

  • Sign: A reduction in water flow or pressure in your hot water supply might be due to a clogged filter or aerator.
  • How ROMA Can Help: Our service includes cleaning or replacing filters and aerators, and checking for any blockages in the lines.

4. Error Codes on the Display

  • Sign: Most modern tankless water heaters have digital displays that show error codes when there are issues.
  • How ROMA Can Help: We can diagnose the problem based on the error code, and make the necessary repairs or adjustments.

  • Sign: Rumbling, clanging, or whining noises from your tankless water heater could indicate a serious problem, such as a failing component or scale build-up.
  • How ROMA Can Help: We can flush the system or replace any components that may be causing noise due to wear or damage.

Calculating the Right Tankless Water Heater for Your Home

Selecting the right tankless water heater involves understanding various factors that affect water heating requirements. By accurately calculating these needs, you can ensure your water heater is efficient, cost-effective, and provides a steady hot water supply. Here’s a detailed breakdown of how to calculate the correct tankless water heater size for your home, including tables and lists to simplify the process.

Key Factors in Choosing a Tankless Water Heater

  1. Flow Rate (Gallons Per Minute – GPM)

    • Definition: The amount of hot water the heater can produce at a given time.
    • Consideration: Calculate the number of fixtures (faucets, showers, appliances) that might use hot water simultaneously.
  2. Temperature Rise

    • Definition: The difference between the incoming water temperature and the desired output temperature.
    • Consideration: A higher temperature rise requires a more powerful heater.

Steps to Calculate Your Needs

  1. Determine Peak Hot Water Usage

    • List all water fixtures and their average flow rates (GPM).
    • Calculate the total flow rate by adding the flow rates of all fixtures that might be used at the same time.
  2. Calculate Required Temperature Rise

    • Estimate the average incoming water temperature for your area (colder climates will have colder incoming water).
    • Subtract this from your desired water temperature (typically around 120°F).
  3. Selecting the Right Model

    • Use the combined information of flow rate and temperature rise to find a heater that meets these requirements without overcapacity.

Example Calculation Table

Here’s an example table calculating the flow rate needed for a typical family home:

FixtureFlow Rate (GPM)
Shower2.5 GPM
Kitchen Faucet1.5 GPM
Bathroom Faucet1.0 GPM
Dishwasher1.5 GPM
Total6.5 GPM

Assumed incoming water temperature: 50°F (common in colder climates)
Desired output temperature: 120°F
Temperature rise needed: 70°F

Using this information, you would look for a tankless water heater that can handle at least 6.5 GPM with a temperature rise of 70°F.

Considerations for Energy Efficiency

  • Energy Factor (EF): Higher EF ratings mean greater energy efficiency. Consider models with an EF rating of 0.90 or higher for the best energy savings.
  • Gas vs. Electric: Gas models typically offer higher flow rates and are more suitable for larger households with higher hot water demand. Electric models are easier to install and maintain but might be better for smaller households.

Installation Considerations

  • Professional Installation: Ensure that your unit is installed by a qualified professional to meet safety standards and optimize performance.
  • Ventilation: Gas models require proper venting to expel exhaust gases.
  • Space: Even though tankless units are compact, consider the space for potential future maintenance and ease of access.
