"I planned to change out my old standard water heater with a tankless unit some time this year. Got an ad last month advertising JL Anderson does this so out of curiosity I called for an estimate and met with Richard a few days later. I didn't realize until speaking with them this new style requires slightly different venting and plumbing but Anderson could oversee the whole thing. Because they handled the entire installation of my HVAC system a few years back and did a great job I knew they'd be perfect to do this install. We're loving this new system already and can't wait to see the benefits it shows over time. Once again they were great to show me my options, explain the process and provide a quick/simple install (only took a few hours-thanks Curtis!). I called them a few days later with a question unique to my situation-Joe took my call and was very helpful-just as he was years ago. Total experience went smooth and I'm confident they back up whatever they do. I highly recommend JL Anderson-you'll be happy with their work!"

"I call Hater Heater Express based on previous reviews. Jeremy Williams took my call and after I explained that I needed to replace my 18 year old water heater, he asked what time of the day would be best to come out and take care of my replacement. He explained that he liked to provide same day service and any hours I would be available would work for him. We agreed to meet at my house at 3:30pm and he estimated that the time to replace my water heater with a new one would take about an hour. He also provided an all-inclusive price to remove and haul away the old water heater, install a new unit. In short, Jeremy arrived on time, completed the install in under an hour and charged my as per his original quote. I highly recommend Water Heater Express of Lafayette."

"Service guy came as scheduled. Sent his "service" requirements to home base Home base calls back and lists, a very long list of what needs to be done and a very long list of what is not covered and what each item costs. The overall cost was outrageous and they weren't willing to give it to me in writing. Everything I had to pay for was overpriced, of course! They told me my other option would be to purchase my own water heater and they would reimburse me for what there water heater would cost, but no reimbursement for Labor, building permit, or any upgrades required by the local building department. The requirements of the building department were minimal. I went to Home Depot and had them do the installation and saved many hundreds of dollars. Lesson learned, have AHS do simpler repairs that don't require municipal building department approval. Have AHS pay for the equipment, and purchase installation from a trusted local installer."

Water Heaters FAQs, answered by experts

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

The average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

Flushing biannually, checking the anode rod, and temperature settings maximize equipment lifespan while reducing surprise costs.

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.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.
