Can you switch to a tankless water heater from a heater with a tank?

• <div><p>Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.</p></div>

Do electric water heaters waste electricity?

• <div><p>If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or <a href="https://www.angi.com/articles/how-to-turn-up-water-heater-temperature.htm">lowering the temperature of the water heater</a>. </p></div>

How much water should come out when draining a water heater?

• <div><p>The average water heater holds between 40 and 60 gallons, but the exact amount of water that comes out during draining will depend on your unit’s capacity. The amount of <a href="https://www.angi.com/articles/how-long-drain-water-heater.htm">time it takes to drain a water heater</a> averages from 10 to 30 minutes.</p></div>

Q: Are hot water heater expansion tanks necessary or required by code?

• <div><p>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.</p></div>

Q: What is the proper vent pipe for a water heater?

• <div><p>Due to the high temperature, using stainless steel vent pipes for your tankless water heater&rsquo;s exhaust vent is best. Also, it is safe to use a flexible vent duct as the exhaust fan. If installing the exhaust fan yourself, make sure you are using heat-resistant silicon to connect the exhaust vent and the duct on your water heater.</p></div>
