"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

In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.

Water heater installation code requirements are in place to keep your family and home safe. Water heaters that are installed wrong can simply not work. However, that's an, if you're lucky, type of situation. More commonly, incorrectly installed water heaters pose a real threat from carbon monoxide poisoning, gas leaks, water leaks, and even explosions. 

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.

It takes between one and three hours to replace a hot water heater element, depending on whether you hire a pro or do the work yourself. For example, a professional plumber with all the necessary tools and experience can often finish the job in one to two hours, whereas DIY will take two to three hours because it'll involve more preparation and troubleshooting.

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.
