"My hot water heater was replaced the same day. Old hot water heater was installed in 2000 so it didn't owe us anything. Done Right Today was courteous, professional, and offered a reasonable price. My wife and I were very pleased with their work. David and Jan Magaha"

"Fabulous! We needed our water conditioner serviced and other company wouldn't touch it because they didn't install it and just wanted to sell us a new one. Rebecca scheduled us for the following day! Steve Venditti was great, has 20 years of experience and knew what he was doing. He spoke with the manufacturer and they decided what needed to be done. He had the parts on his truck and 4 hours later the job was done. $500 included parts and labor and service call. Very fair price and excellent service. Totally professional. Highly recommend."

Water Heaters questions, answered by experts

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. 

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.

The size needed for your expansion tank is determined by the size of your home's water heater. Expansion tanks are available in 2-gallon and 4.5-gallon sizes. A 2-gallon tank will be appropriate for water heaters up to 50 gallons. An adequately sized tank should have a volume that equals 2% to 5% of the water volume within the system. A plumber can evaluate your home's water pressure, water heater size, and other factors to provide suggestions for picking out the best expansion tank.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

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.
