"The crew was on time (slightly ahead of schedule), through in their work, professional, cleaned up before/after, and highly responsive. Scheduling was done through text, as was the pre-consultation. Further, PorterHouse was price competitive, and offered me one of the better quotes/prices for a water heater replacement."

"Outstanding service from start to finish. The technicians were phenomenal and took care of every detail, from removing our old unit to installing the new tankless water heater. The job required custom retrofitting and running new piping to make sure the unit fit properly, and the crew handled it all seamlessly. Clean, efficient, and top-tier craftsmanship. I couldn’t be happier with the results and highly recommend them."

Water Heaters questions, answered by experts

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

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.

Typically, only a high-efficiency water heater with an inducer fan can be vented outside the house. Otherwise, your water heater needs to be installed on the inside and vented through the roof. However, certain areas may allow a standard-efficiency water heater to be vented outside. Check your local building codes to be sure.

In most municipalities, a license is not mandatory for water heater installation or replacement. However, we strongly recommend hiring a licensed plumber or water heater installer to handle the work. Licensed installers are far less likely to make a mistake during the installation, which means paying for the experience decreases your risk of a leak and other issues. You can use our state licensing tool to find out if a contractor you’re considering in your area holds a plumber’s license.
