Q: Does an electric water heater need its own circuit breaker?

• <div><p>A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.</p><p>Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code&ndash;and to ensure it runs as efficiently as possible.</p></div>

Q: How big should a hot water heater expansion tank be?

• <div><p>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.</p></div>

Q: What’s the best place in my house for a hybrid water heater?

• <div><p>Basements, specifically those without any air conditioning, are the best location for a hybrid water heater. These rooms are less likely to experience extreme temperature fluctuations, which can affect your hybrid water heater&rsquo;s efficiency and performance. Basements often have more than enough space for their tanks and proper air circulation. Hybrid water heaters can also be a bit noisy, but putting them in your basement will keep the noise away from your main living areas.</p></div>

Q: Is 20 years too old for a water heater?

• <div><p>If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.</p></div>

Q: Can you switch to a tankless water heater from a heater with a tank?

• <div><p>Yes, you can replace a current tank water heater with a tankless model or vice versa. If you&rsquo;re maintaining the same fuel source&mdash;gas or electricity&mdash;the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you&rsquo;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.</p></div>

I contacted them on short notice and told Clint we had a family event planned the next day that we would like to have the windows cleaned inside and out before that happened. Clint made a space for us in his busy schedule and came out that afternoon same day. They did a great job! Thanks so much...

"I have used the company several times. They are up front with an estimate that they stick too. They arrive when they say they will and even give you a notice by phone when they are a few minutes away. No problems with their work at all. Today I called them and they came out. It was more of a 'boiler issue' to which I was referred to a company specializing in boilers. I wasn't charged a dime, even with him quick fixing a leaky shut off valve. Most places would have at least charged me for a minimal service charge just for showing up. They do business the old fashioned way and they will be my plumbing people from now on."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."
