United Plumbing’s Comprehensive Guide to Selecting the Correct Breaker Size for Your Tankless Water Heater in Los Gatos

August 4, 2023

In the realm of home appliances, an energy-efficient and reliable solution that stands out for providing endless hot water is the tankless water heater. However, it isn’t as simple as plug-and-play to install it. One crucial consideration is selecting the correct size for the circuit breaker. United Plumbing, Los Gatos’s reputable water heater service provider, is here to guide you through this process.


The Breaker Size and Its Importance in Tankless Water Heaters: Understanding the Basics

Before delving into the specifics of selecting the appropriate breaker size for your tankless water heater, understanding its significance is crucial.

The Role of Correctly Sized Breaker

In an electrical circuit, the breaker serves to shield it from overloading. The breaker ‘trips’ or breaks the circuit when it draws current beyond its capacity, thus averting possible hazards like electrical fires. For a tankless water heater, a breaker of the right size guarantees the unit operates safely and at its best.

Essential Factors in Choosing Breaker Size for Your Tankless Water Heater

Consider these key factors when determining the size of the breaker for your tankless water heater:

  • Power Rating of Heater: This is the electricity amount, measured in kilowatts (kW), used by the heater when it operates at full capacity. Larger breaker sizes are required for higher power ratings.
  • Supply of Voltage: In the U.S., the standard voltage for residential electrical systems is either 120V or 240V. The breaker size is directly influenced by the supply voltage.
  • Heating Elements Count: Depending on the model, tankless water heaters can have multiple or a single heating element. The breaker size is influenced when the total power is divided among multiple elements.

Building Codes in Your Local Area: The breaker size and overall electrical setup may be influenced by specific building codes in different regions.

A Basic Guide to Calculate Breaker Size

Follow this straightforward calculation for a rough estimate of the right breaker size:

Size of Breaker (in Amperes) = Power Rating of Water Heater (in kW) x 1000 / Voltage Supply

Bear in mind that this is only a rough calculation and might not take into account specific manufacturer’s instructions or local building codes. Consulting a professional plumber before making a final decision is strongly advised.

Bella is very knowledgeable about tankless water heaters. She determined that the heater that I purchased from Amazon was the wrong model. She went above and beyond the call of duty. She drove me in her car to the UPS store so I can return the heater and then drove me to the supplier store in San Jose (Pace Supply) so I can buy the correct one. She is very honest and showed me the wholesale price of the heater and used her coupon to get me the wholesale price. Umed, the technician, is an expert and did a great job installing the unit. He arrived on time, was very polite, and cleaned the area after his work was done. Bella and Umed put the customer first and provided an excellent service. I highly recommend United Plumbing because of Bella and Umed, their honesty, great service and expertise.

Technician Beck came on thanksgiving day, working from 3pm till almost 9pm, to replace a new water heater. In the middle of the installment, he even had to go back to his office and pick up new parts. It was very difficult to set up the tubes at my place since the space for the tubes/water heater was limited. Technician was very patient and friendly the whole time. The pipes after Beck’s work are better designed. I am very grateful they are willing to come on a big holiday like thanksgiving, getting the challenging work done without any complaints. Otherwise it would be a cold shower thanksgiving for us. Highly recommend.

United was quick to do an inspection and quote to replace our 20 year old tank water heater for a tankless and was able to start the job the same day. Professional and great service and the price was the lowest I received out of 3 or 4. Highly recommend!

Yuri was great! Yuri came to inspect the pipes that were hearing while the water is running but unfortunately we weren’t able to hear anything at the time of the inspection. Yuri was able to install a new faucet in my kids bathroom. If you are looking for a plumbing company use United Plumbing, from the office to the field the service was great! I will definitely use Yuri and United plumbing again in the future.
