Sizing Your Battery Backup: Power Requirements for Noritz Models

Choosing the right size battery backup for your Noritz tankless water heater is critical. An undersized system will not provide enough power. An oversized system means wasted money. Understanding your unit’s power needs is the first step.

Every Noritz tankless water heater has specific electrical requirements. You can find this information on the data plate or in the owner’s manual. Look for ratings in Watts (W) or Volt-Amperes (VA). You will also see Amps (A) and Volts (V). Watts represent the actual power consumed. VA represents apparent power, which is important for sizing UPS systems. For inductive loads like fans, VA can be higher than Watts.

Most residential Noritz tankless heaters operate on standard 120V AC. They typically draw between 100 to 200 Watts during active operation. This is for the control board, igniter, and exhaust fan. The unit does not pull power constantly; only when hot water is flowing.

To calculate your required battery capacity, consider:

1. Noritz Unit’s Wattage: Find the operational wattage. Let’s say your Noritz uses 150 Watts.
2. Desired Run Time: How long do you want hot water during an outage? For instance, 4 hours.
3. Total Watt-Hours (Wh) Needed: Multiply wattage by run time. 150 W * 4 hours = 600 Wh.
4. Battery System Efficiency: Battery systems are not 100% efficient. Account for 80-90% efficiency. So, divide your needed Wh by 0.8 or 0.9. For 600 Wh, you would need 600 / 0.8 = 750 Wh battery capacity.
5. Inverter Size: The inverter converts battery DC power to AC power for your Noritz. It must handle the peak wattage. Use the continuous wattage of your Noritz. An inverter rated for 300-500 Watts continuous output is usually sufficient for residential tankless heaters. Always choose a pure sine wave inverter.

Here’s an example:

• Your Noritz model N-084M requires 120W of operational power.
• You want to run it for 6 hours during a power outage.
• Total power needed: 120 W * 6 hours = 720 Wh.
• Factoring 85% efficiency: 720 Wh / 0.85 = approximately 847 Wh battery capacity.
• Look for a portable power station or UPS with at least 850 Wh capacity. Ensure its inverter can provide 120W continuously and is pure sine wave.

It is wise to slightly overestimate your needs. This gives you a buffer. Remember, batteries lose some capacity over time. Consider how often you use hot water during an outage. You might only need it for specific times of the day. This planning ensures you pick a system that truly meets your needs. Proper sizing guarantees hot water access when you need it most.

However, if the municipal gas supply system relies on electrical pumps or monitoring that loses power, your gas supply could be affected in very rare, widespread outages. This is generally not a concern for short-term residential power cuts.
• Propane (LP Gas): For propane tank users, your supply is self-contained. As long as your tank has fuel, your Noritz heater can use it. This makes propane models excellent for off-grid or remote locations, especially when paired with a battery backup. Ensure your propane tank is adequately filled before an anticipated outage.
• Pilot Light: Modern Noritz tankless heaters use electronic ignition. They do not have a standing pilot light. This means they are entirely dependent on the battery backup for ignition. Older tank models might have a pilot light.

Protection Against Freezing:

• Tankless Heater Freeze Protection: Noritz tankless heaters have built-in freeze protection. This feature uses a small amount of electricity to warm the heat exchanger when temperatures drop. This prevents water inside the unit from freezing and causing costly damage.
• Battery Backup and Freeze Protection: Your battery backup must be able to power this freeze protection feature. If the battery backup system dies or is too small, the freeze protection will fail. This is critical in cold climates. Always ensure your backup system can sustain this minimal power draw during an outage.
• Draining the Unit: For prolonged outages in freezing temperatures, especially if you anticipate the battery running out, draining your tankless water heater is the safest option. Refer to your Noritz owner’s manual for specific draining procedures. This prevents internal pipe bursts. It requires some effort but protects your investment.
