"Bruce really listened to how I answered his questions and designed a natural-gas fueled steam boiler system that met all the requirements with the expansion potential I requested. During pre-installation logistics and the day of installation, Bruce and his crew were on-time, courteous and professional. Their work demonstrated the benefits of hiring a fully credentialed company, skilled and experienced at their craft. They completed their work in one very long day so that I could avoid a night without heat during a stretch of very cold January days. I trust Williams & Assoc. and would hire them for additional work in my home as needed"

No mess, all cleaned at completion with a very good looking new hot water heater. All in all we are very satisfied. Yes, I would definitely use again. Highly recommend."

Water Heaters questions, answered by experts

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.

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

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.

Depending on the brand of water heater, you may need to install an expansion tank in order to meet the conditions for warranty coverage. It’s important for consumers to read the fine print of the warranty to see if an expansion tank is necessary. Even if an expansion tank isn’t required for the warranty, it’s usually mandated by building codes—although not for tankless water heaters.
