"⭐⭐⭐⭐⭐ Excellent Service – Highly Recommend! We recently had our water heater replaced by Northwest Plumbing, Heating & AC, and we couldn’t be happier with the experience. From start to finish, the team was professional, knowledgeable, and easy to work with. They showed up when promised, explained everything clearly, and completed the installation efficiently and professionally. The workmanship was excellent, they kept everything clean, and made sure the new water heater was working properly before they left. It’s refreshing to work with a local company that takes pride in its work and genuinely cares about taking care of its customers. If you need plumbing work or a water heater replaced, I would absolutely recommend Northwest Plumbing, Heating & AC. Five-star service all the way!"

"My water heater was not making hot water. Steven came promptly and on time. He had the experience and skills to quickly diagnose and proactively treat the problem and prevent a recurrence. He was patient with my hovering around and asking questions and even offered helpful information when he sensed I was curious. He completed the job professionally and efficiently and economically as possible and advisable. I couldn't be more pleased with his work."

"A little high priced for a toilet repair. The stopper was not fitting on the seal when you flushed causing it to run constantly. $395 was a pretty high in my opinion for a $20 toilet kit. We should have done that ourselves. Water Heater did have problems and we were happy to get a new one and have installed. There again, paid a high price for water heater."

Water Heaters FAQs, answered by experts

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of time it takes to drain a water heater averages from 10 to 30 minutes.

Signs your electric water heater is failing include inconsistent water temperature, reduced hot water supply, longer heating times, or discolored water (rusty or cloudy). Unusual noises like popping or rumbling suggest sediment buildup, while leaks or corrosion around the tank signal structural damage. If your unit is over 10 to 15 years old and experiencing frequent issues, it may be time to replace it.

The average lifespan of a water heater is eight to 12 years. If your water heater is approaching its first decade of life and is giving you problems, talk to a plumber about your replacement options.

Keep in mind that certain parts of a water heater, such as the anode rod, may need replacement long before the heater itself. An anode rod often has a lifespan of three to five years.

A tankless water heater with a flow rate of 10 GPM should replace a conventional 50-gallon water heater. To avoid a surprise cold shower or two and to keep your energy costs in check, it's important to replace a conventional tanked water heater with the equivalent tankless water heater. Your household size and the number of hot-water-using devices you use at once can help you determine the best-size tankless water heater.
