"I was very impressed with Mr. Chris Massey! I placed a call to him at about 9:10 in the morning to request a quote for a hot water heater replacement. I received his voicemail; however, within only 20 minutes he called me back and was apologetic for missing the original call. I could sense at that point that he was a sincere individual. I explained to him that my electric water heating unit was located in my crawlspace. I also provided him with the dimensions of the tank and its accessibility in said crawlspace. He responded as if he had completed these type of projects countless times in the past. Without even looking at it he gave me a quote right there over the phone. After doing some research I knew that it was a very reasonable one so accepted it immediately. He then told me that he could pick up a new unit and be at my house by around noon. He was actually pulling into my driveway before 11:00 AM. He finished the whole removal/installation process in under two hours and filled me in on everything that he did. He was intelligent, personable and quick. I'd give him 7 stars if I could. This gentleman is truly a class act!"

"The owner and co-worker came out yesterday for a quote and they were very honest and professional and being that they had really great reviews, I went with them. They came out today and had the work done in 3 hours (we had a hot water heater relocated from our laundry room to the garage) and fixed 2 outside faucets that haven’t worked in a long time. With that being said, when I say they were professional about everything, they were! There was no mess from them at all, they cleaned as they went which goes a long way in my book. I would definitely recommend this company to anyone that needs any sort of plumbing work done."

Water Heaters FAQs, answered by experts

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

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.

Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty. However, even if you get away with performing the task yourself, incorrect installation, lack of a building permit, and improper repair work, regardless of licensing status, can all render your water heater unprotected by both the manufacturer's warranty and any installation warranties. 

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 you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.
