What size water heater does my house need?

• <div><p>If you're replacing a broken water heater, now is a great time to make sure you're selecting a unit that has the right capacity for your household. According to the<a href="https://www.energy.gov/energysaver/sizing-new-water-heater"> U.S. Department of Energy</a>, a small 50-gallon to 60-gallon tank is sufficient for households with one to three people. A medium-sized 80-gallon tank is considered ideal for three to four people. A larger tank may be needed if your household has four to six people.</p></div>

Are hybrid water heaters noisy?

• <div><p>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.</p></div>

On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a <a href="https://www.angi.com/nearme/water-heater-installation/">local water heater installation company</a> and local building codes to confirm which permits are required and what the specific laws are.</p></div>

Q: Is it hard to replace an electric water heater?

• <div><p>Unless you have previous plumbing experience or extensive experience with water heaters, <a href="https://www.angi.com/articles/can-install-water-yourself.htm">you should avoid replacing your electric water heater yourself</a>. This process involves disconnecting wiring and parts from the old water heater and reinstalling them onto the new one, among other difficult tasks. This job is best left to the pros to make sure that everything is connected correctly to avoid serious leaks or malfunctions.</p></div>
