"EXCELLENT CUSTOMER SERVICE Eddie visited our house the very day we called about our water heater. He came out, inspected the very tough location where the water heater is located and delivered an estimate with 3 options on the spot. We decided which direction to go and let Eddie know at which time he promptly scheduled our installation. On the day of install he arrived when he said he would, put down every type of floor protection you can imagine and proceeded the very difficult task of manipulating a 50 gallon water heater out of a small closet 10 feet up in the air. He worked with his partner to remove the old one, replumbed and installed the new one, again in a very tight space. Eddie ran all new venting to the outside, added electronic monitoring, and crawled under the house several times to make certain the drains were all functioning properly. We could not ask for better service and the attention to detail was amazing. This is our second experience with Excalibur Plumbing and they have both been wonderful experiences. Great customer service!!!!"

"Fantastic. Everyone at Cold Is On The Right, from Kari in the office to Billy in the field, is terrific. Our job was complicated: remove two conventional hot water heaters, one of which was in the attic, and replace them with a tankless system. In addition, our house had two separate water loops, which need to be merged into one. Cold Is On The Right did everything on-time and on-budget. They're professional in every way. I recommend the company unreservedly and count myself a customer for life. Jeff Bowden, Austin."

"We recently had Colin install our new water heater, and the experience was truly excellent from start to finish. He was friendly and patient, taking the time to walk us through the process and explain the new unit. What stood out most was the detail-oriented nature of the work; everything was installed perfectly. When the job was complete, the work area was meticulously cleaned up. The new water heater is working perfectly, and we are very satisfied. We would absolutely call 1-800-Plumber+Air again for any future plumbing needs."

Water Heaters FAQs, answered by experts

The average lifespan of a water heater is eight to 12 years. If your water heater is approaching its first decade of life and is giving you problems, talk to a plumber about your replacement options.

Keep in mind that certain parts of a water heater, such as the anode rod, may need replacement long before the heater itself. An anode rod often has a lifespan of three to five years.

You don’t have to replace expansion tanks at the same time as your hot water heater. You may be able to go six to 12 years or more before needing to replace your expansion tank. At $150 to $450, hot water heater expansion tanks are usually much more affordable than the cost of hot water tanks themselves, which average about $1,190.

The good news is that most home warranty plans cover hot water heaters, regardless of whether you have a tank or a tankless model. Your hot water heater should be covered by your home warranty because it's considered an essential home appliance.

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.

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–and to ensure it runs as efficiently as possible.

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.
