Is ventilation necessary for water heaters?

• <div><p>Not all <a href="https://www.angi.com/articles/types-of-water-heaters.htm">types of water heaters</a> 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. </p></div>

Q: What factors affect the cost of water heater installation?

• <div><p>Price variations arise from size, type (tankless or tank), efficiency grades, and installation complexity, including labor and materials.</p></div>

Q: Can you install an expansion tank anywhere?

• <div><p>No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There&rsquo;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. </p></div>

Q: Should I replace my 20-year-old gas water heater?

• <div><p>If your gas water heater is over 20 years old, it should be replaced. Gas water heaters can last up to 12 years and while they can exceed this expectancy if well-maintained, a heater that's 20 years old would require replacement. The heater is unlikely to run as efficiently as a new model and could be more expensive to do so.</p></div>

Q: What size circuit breaker does a water heater need?

• <div><p>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.</p></div>
