"I am completely satisfied with Becks. Every encounter from initial txt msg through phone call, scheduling, meeting the technicians, and their work in assessing and completing the repair was exemplary. My job was done in a timely manner which was a relief as another company quoted me a 4 day delay. My water was off at the main so I really didn't want to wait that long. The technicians were knowledgeable and professional and answered my questions. They left no mess behind. I have some future upgrades in the planning stage and will definitely consult with them at that time due to the experience I had today. So, in short, my water is back on. My leak is gone. The technicians were wonderful. I recommend Becks without reservation"

"I woke up yesterday to find I had no hot water. As soon as I logged on to HomeAdvisor to look for a plumber to replace my old water heater Andrew Hornbeck of Hornbeck Plumbing and Heating called me immediately. He came to my house that afternoon, gave me an estimate, and my water heater was replaced by 6:00 pm the same day. How's that for prompt service in an emergency situation! He was courteous, knowledgeable, and nothing but professional. He and his employee did an impeccable job of cleaning up and they even unclogged a drain for me which was not part of the job. I am having Andrew come back to my house next week to replace my kitchen sink since he did such a good job on my water heater project. Karen Morgan in Doylestown"

Water Heaters FAQs, answered by experts

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 want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.

Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters—both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your water heater needs to be replaced, so pay attention to anything that changes with your heater or hot water.
