"Of the four companies to look at my tankless water heater installation, Bill was the only one to suggest an alternative location that would be less expensive to install and much more serviceable in the future. He thinks like a homeowner, not some corporate guy trying to gouge the customer. I have already had him look at a second project and he had a great alternative to offer."

"They were quick to reply to my quote request and Blain arrived when they said he would. I noticed my water heater had gone bad around 11:00am and they had the new one installed around 6:00 the same evening. Blain was extremely nice, professional, and respectful and the work seems to be top notch."

Water Heaters FAQs, answered by experts

While not all homes require a hot water heater expansion tank, they are necessary in most newer homes and are often mandated by local building codes. Codes typically require an expansion tank if your plumbing system is a 'closed-loop' system, which often includes a backflow preventer or pressure regulator on the main water line. Some municipalities have specific requirements. Installing an expansion tank on a closed system is crucial, as it prevents excess pressure that can damage your water heater and other appliances, potentially shortening their lifespan. However, tankless water heaters do not require an expansion tank.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

We recommend you turn off the unit, the power, and the water supply as soon as you notice a leak. Your water heater tank should have a dedicated shut-off valve located on the cold inlet pipes. If the valve is broken or inoperable, use the shut-off valve to your home's main water supply to stop the flow to the entire house.

Avoid touching valves or pipes directly without confirming if they are hot. Wear gloves and other safety gear to keep from coming into contact with hot levers or components when turning off your leaking water heater.

Yes, you can convert a gas water heater to an electric one, but it is a complex process. You will need to ensure there is adequate power for the new electric unit, as they require more power than gas models. The project also involves safely closing off the gas lines and ventilation, and some cities may require a permit for the conversion. The cost can range from $1,500 to $4,100, depending on the installation scope, plumbing and electrical work, and the water heater model. For an accurate quote, it's best to contact a local professional. Also, be aware that your monthly utility bills may increase after the conversion, as natural gas is typically cheaper than electricity.

Yes, hybrid water heaters can be noisy — noisier than traditional water heaters. The sound they produce is often compared to the hum of a dishwasher. Its noise comes from the heat pump’s fan and compressor as they work to pull in and compress the air. While it’s not totally disruptive, especially if the unit is installed in less frequented areas, like a basement or garage, it’s something to keep in mind if you’re sensitive to noise or if the unit will be placed near bedrooms or living spaces.
