"The whole experience replacing the water heater from the beginning to completion of the job was excellent. I do not have any complaints. I shopped around to other water heater company's and nobody could even come close with price or workmanship to premier water heaters. I would not have any problem recommending premier water heater"

"My technician Kyle was very informative and respectful. He explained what was going on and was very professional. Kyle even left me with an electric heater for the evening until they could replace my furnace the next day. Kyle was back early the next morning to start the replacement of my old furnace for the new one and it is working great! I am so happy that I was able to get this done right away."

"It went very, very well. I called Windy City Rooter at 8am and before 11am they were fixing the water heater. I thought a new one was needed but that was not the case. The temperature & pressure valve caused the leakage. it was replaced immediately. James and Justin were very friendly, courteous and professional. Both provided excellent service."

Water Heaters questions, answered by experts

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

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.

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

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.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.
