"Chris with Friesen Family Renovations, LLC was very professional and thorough in the work he has completed. He installed a new screen door, replaced my tub stem and faucet, repaired my subfloor in the kitchen and installed brand new LVP flooring to replace old and water damaged flooring. He also mounted a television for me, and did some drywall repairs as well. I would recommend this business to anyone looking for quality and dependable work!"

Water Heaters questions, 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.

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.

Installing a water heater without a permit can result in high fines—as much as hundreds of dollars per day, in some areas. It can also void your homeowners' insurance and cause problems when selling your home because it violates local building codes and safety regulations.
