"I want to thank Hosack Plumbing, and Kent, for getting my situation cleaned up quickly and professionally. My water heater install is perfect, my water pressure spot on thanks to the new PRV, and is ready for inspection. Kent was thorough, professional, and very clean. He noticed my mask when I answered the door and wore a kn95 mask the whole time. The life coaching advice was an added bonus. Kent's work was great and I'm very pleased with the service provided."

"This was a complex retrofit tankless water heater installation and out of 30+ companies called and solicited for this project, Brett and Dunn's HVAC was the only company to 1) entertain performing the installation correctly (gas line sizing and calculations), 2) had prior experiencing working with tankless heaters, and 3) took the time to work with me on a long list of specifications. These are bulletproof systems if the installation is done correctly and Dunn/Brett took the time to ensure the install was on point and everything went smoothly. They also installed a softener and filtration system. Everything went well from bid to install and I highly recommend Brett and Dunn's - will use again as I could not be more pleased!"

"Steve arrived on time, quickly diagnosed the problem with the water heater, gave me options to fix/replace without trying to steer me to one option or the other, and answered my questions. I opted for replacement and he got the appointment set up for the next day so we wouldn't be without hot water any longer than necessary."

"We chose Total Comfort Heating & Air Conditioning, LLC to replace our 40+ yr old HVAC system. The salesman (*Ken Ross) was knowledgeable and friendly. No hype, no sales pitches and no up selling. The Installers were punctual, pleasant, fast, and left the work area spotless. I would highly recommend this company to anyone in need of quality HVAC Services."

"My hot water heater went out. I called several plumbers and was being quoted astronomical amounts along with quite a wait time to get to me. Brice was able to get the job done quickly (since no hot water sucks) and at a price I could live with. He was super funny and professional and made me feel like a friend had come over to help. I will always call him first for any of my plumbing needs"

Water Heaters questions, answered by experts

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.

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.

No, you’ll need to drain the tank before changing a water heater element, as the water heater element sticks through the side of the tank and uses a gasket to prevent water from pouring out. However, you don’t always need to drain it completely. If you’re only replacing the upper heating element, you can drain the tank until the water line is below the element. If you’re replacing the lower element, you’ll need to drain the whole thing.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

When replacing an old unit, you might want to switch from a gas water heater to an electric water heater or vice versa. To do this, you will likely need to add infrastructure to the area. For example, you likely don’t have a gas line that served your old electric water heater. You’d have to call a plumber to put in a new gas line. If you’re replacing a gas unit with an electric one, the plumber will need to safely cap the old gas line. You will then need an electrician to add wiring for the new electric unit.
