"I had a 20+ year old water heater. The expansion tank developed a leak. I contacted Wagner and Sons. Mike gave me a suggestion to temporarily fix the leak. After discussion I contracted him and his son to replace the water heater and expansion tank. He said he could be there at 12:00PM on Monday. He was right on time. He replaced the water heater and the expansion tank in just over one hour. Hauled away the old heater for free."

"They came in the time allocated. I had two areas I needed looked at , main shut off waterline which some tightening of fittings that were done. The other was replace a part in the faucet if the tub that mixes cold an warm water. Only the cold worked. He tried to loosen and clean the warm part, it needed to be replaced. They went to the local hartware and purchased it. It now works fine now. One suggestion would be that every time an additional charge was mentioned, I had to ask specifically how much it would add to the total bill. I definitely will hire him again."

Water Heaters questions, answered by experts

If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the U.S. Department of Energy, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

No state requires you to vent an electric water heater. Other installation requirements for water heaters will vary, though, depending on the state and local jurisdiction in which you live. Some places require permits, while others don’t. Some may force you to place the appliance a certain distance from any walls or other appliances, while others don't. When you find a local professional to install a water heater, this expert will ensure you follow all the local regulations.
