"Robby not only helped me with a complete remodel of my bathroom but also replaced my hot water heater and made a new connection for a washing machine to be moved inside the house while turning the old connection, in an outside shed, into a much needed utility sink. All work was done in Jacksonville, FL at 3235 Hickorynut st. The bathroom remodel was on a very tight time schedule of 4 weeks and a complete gut job. Robby was an absolute professional and able to make the 4 week goal from start to finish. Pricing was very affordable for the remodel, new washing machine connection, utility sink install and hot water heater replacement. Always on time and great communication throughout the project. Call him with your project ideas and plumbing needs and you will not be disappointed. Highly recommend this plumber!"

"A pipe that supplied the hot water heater was leaking water onto the floor in the garage. Zef and an assistant from Flow Solutions was able to arrive within a couple of hours of my call. The problem I could see was that water was on the floor under the water heater. They quickly found the problem in the wall behind the water heater. They pulled out the wet drywall and the insulation, found the leaking pipe and replaced it. I liked it that Zef told me about the licenses he holds for doing this work. He explained to me that the wall must be left open to let it dry well before repairing it. (I will most likely be contacting the person to repair the drywall and insulation through this wonderful service, HomeAdvisor, Inc.!!)"

"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."

Water Heaters questions, 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

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit. 

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.
