"I would absolutely recommend water heater express to anybody that needs a water heater replacement. As luck would have it they were able to replace my tankless the same day I called which was great because that way whenever my wife got home from her work trip she had hot water for her much needed R&R in the tub when she got home."

"Dave picked up the new water heater at Home Depot and arrived on site with time to spare. The installation went smoothly. Once completed, Dave discussed the operation of my pressure reducer valve (PRV) which may need replacement in the future. We also took the opportunity to "chew the fat" and swap "war stories". I would definitely ask for Dave's assistance in the future. RHx"

"The job went great! They were able to remove a very large drainpipe that was 5 feet below the road. Additionally they installed a larger pipe for us, and did an excellent job getting it seated in place and covering it up. The road going into our farm doesn't flood anymore and the water is able to drain nicely on the sides where they helped dig the angle much better than any piece of farm equipment we had on hand. Mr. Lozy was kind enough to help us dig a really small pond for the deer as well. With his excavator it took 3 minutes, what would have taken me 18 hours and a broken back to do with a shovel."

"My husband and I were referred to CGC Water by close friends. Everything from the first appointment with the sales man to having the project complete felt very intentional and customer focused. They took water samples, listened to what we wanted, answered all of our questions (we had plenty) and set us up with everything we needed. I was really happy that they got us on the schedule quickly, we did not have to wait 4+ weeks that other projects have taken. The install was very thorough and even though nobody will see the equipment the install spot was left clean and the piping all looks nicely hung. That may not matter to everyone but I noticed. Before leaving, the technician made sure all equipment was working and retested the water to make sure it meets our expectations. Now we have a Kinetico whole house water softener, and a Kinetico RO drinking water system. I am so glad we went with the Kinetico system. I can tell a difference in everything! I dont get spots on the dishes anymore, my towels dont smell funky after washing them and having good water has even helped with dry skin. I love the drinking water too! I really can tell a difference from other drinking water and I always fill my water bottle up at home before leaving the house because other water just does not compare. I really appreciate the follow up as well, we opted for the scheduled salt deliveries and filter changes so we dont have to worry about it as much. I highly recommend CGC and the Kinetico water equipment."

"I needed my Water Heater replaced. During the estimate Jamal was straight forward about the pricing and showed me what would be replaced. Didn't try to sell anything that wasn't needed for my household. I also liked the warranty for parts and labor. They did excellent work. Customer Service also was great with follow up calls and appointments. Thank You! Sunday Scarbrough"

Water Heaters FAQs, answered by experts

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection

While possible, professional assistance is recommended to ensure compliance with local regulations and avoidance of avoidable risks.

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.

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.

Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.
