"Quick! Contacted me within minutes of Home Advisors inquiry, showed up and did outstanding work within 3 hrs of initial contact - even though it was a no-rush job. Got my water heater set up in a jiffy; good price and I am glad I called them. Would highly recommend."

"Removed old water heater and installed new water heater and brought water heater up to code. They arrived on time and performed the work efficiently and neatly. The price for the direct vent water heater plus installation was about $250 less than another local quote. Overall I am very satisfied with the price and quality of the installation."

"The technicians are amazing at Ethical Plumbing. My mother passed away and the next week I found a water leak in her basement. I called Ethical Plumbing and they got me on the schedule the very next day and made everything so easy. We have since found a different problem that they also helped us with. Always shows up on time and diagnoses the problem and offers different solutions. Thank you!"

"We had a situation the evening before, with a leak in an upstairs bathroom tub that sent water down into the master bathroom. The remediation company came that next morning to dry things out, but they did not have the skillset to work on the actual plumbing problem. I reached out to Angi's list, put in what I was looking for and selected Three Sons Plumbing. When I hit the go button on Angi's list, I received a call within a few minutes from Brandon the owner. He came over immediately and assessed the problem. He and his helper worked with the remediation team and had the plumbing issue knocked out in less that 45 minutes. Great service. Very reasonable rate. Overall job well done. I would recommend Three Sons anytime. Sean"

Water Heaters FAQs, answered by experts

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

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.

The chemicals in a water softener can wear down the anode rod in the heater and shorten its life span. However, for most people, the benefits of the softener outweigh this potential drawback.

Have a plumber inspect the anode rod annually for damage, as replacing the anode rod is far less expensive than replacing the entire water heater.

You can and should vent the gas from your hot water heater to the outside of your home. Traditionally, these gases were vented back to other gas appliances, like stoves or furnaces, but many jurisdictions have outlawed this practice due to the risks it provides. 

Most water heaters today use atmospheric venting that exhausts the gas out of the home through a pipe.
