"My solar water heater had a leak. He knew right away what to do. They could not fix it on the spot because there was no part. However, they called the next day to set up a new appointment. It took 2 weeks, but it was fixed. I appreciate how helpful they were."

"For three months, I had high water bills. Come to find out I had a leak on the outside of the house and on the inside of the house. Nowhere obvious. Rather than have my floors and yard all tore up I elected to get a full above ground plumbing replacement. Jack did a superb job also arranging for the required holes in the plaster board to be replaced and resurfaced. He was excellent, professional, and responsive. I would recommend him to anyone requiring any type of plumbing need especially a whole house plumbingreplacement."

Water Heaters FAQs, answered by experts

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

The average lifespan of a water heater is eight to 12 years. If your water heater is approaching its first decade of life and is giving you problems, talk to a plumber about your replacement options.

Keep in mind that certain parts of a water heater, such as the anode rod, may need replacement long before the heater itself. An anode rod often has a lifespan of three to five years.

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

If your system is not vented properly, you could experience what’s called backdrafting. Backdrafting is when your ventilation system isn’t working as it should, and instead of releasing gases outside, they get trapped inside your home. 

Gas and propane water heaters create a few types of combustion gases, but the most dangerous is carbon monoxide. If there’s too much build-up of these gases inside your home, it can lead to carbon monoxide poisoning.

Price variations arise from size, type (tankless or tank), efficiency grades, and installation complexity, including labor and materials.
