"Jeremy was very responsive and informative. I had a couple of other quotes that involved various iterations of "replace the old water heater and add these other features at the same time", and we were able to talk through the suggestions and determine what was really necessary. The final quote was very competitive, the new water heater is working great, and the installation itself was fast and without any problems that they couldn't solve without me!"

"Fast response took care of replacing my 20+ year old 120 gallon solar water heater. They ordered the water heater on a Monday afternoon had it installed by Thursday morning. It was not easy finding someone just to swap out a water heater that's for solar. Most plumbers shake in their boots when I mention solar, especially only a water heater swap-out."

"They replaced my tankless water heater, under sink valves with quarter turn ball valves and three toilets. The price was fair, a little high, but the quality of work and service was excellent. These plumbers know what they are doing. They were timely and had good communication."

Water Heaters questions, answered by experts

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

Heat pump water heaters, also known as hybrid water heaters, are the most efficient types of water heaters—both in terms of carbon emission and energy efficiency. This type of water heater utilizes as little as half of the energy of a traditional water heater while releasing no direct emissions. Tankless water heaters are also extremely efficient, although slightly less so than hybrid heaters.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

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.

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.
