"recently had our water heater replaced and had a great experience from start to finish. The team was professional, knowledgeable, and completed the installation quickly and efficiently. They explained everything clearly, cleaned up after the job, and made the whole process stress-free. The new water heater works perfectly, and we couldn’t be happier with the service. I would definitely recommend them to anyone needing water heater replacement or plumbing work!"

"Amazing work they did. I had a water supply leak inside my ceiling which caused water damage to the ceiling. They showed up quickly. Even though the leak was very hard to detect, they did not give up. Found the source and fixed it. Very happy with the work they performed."

Water Heaters questions, 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.

Not all types of water heaters require a venting system. Electric tankless water heaters don’t use natural or propane gas, so no venting is required. Instead, they use electric burners to heat water quickly and efficiently. However, any system that does use gas or propane will require ventilation.

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.

Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.
