"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

A single shower consumes an average of over 17 gallons, while brushing your teeth with the water running uses up to four unnecessary gallons. Watering the lawn spreads hundreds of gallons of water across the yard each time. Limiting water usage in these areas can significantly cut down your water bill.

Due to the high temperature, using stainless steel vent pipes for your tankless water heater’s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.

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.

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.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.
