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>

What is the lifespan of a heat pump water heater?

• <div><p>On average, a tankless water heater should last between 10 and 15 years. Its lifespan will be affected by how much it's used, the effect of weather where your home is on the unit—colder is harsher and will shorten lifespan—and if the heater is maintained appropriately and regularly. There are many signs your <a href="https://www.angi.com/articles/4-signs-your-water-heater-about-fail.htm">water heater needs to be replaced</a>, so pay attention to anything that changes with your heater or hot water. </p></div>

How much does water expand in a water heater?

• <div><p>Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed. </p></div>

These men were very helpful in prep us for the job. They did a temporary hook up so that we would have water at night when we were at home and worked on the wiring and plumbing during the day when we were gone. We experienced little to no inconvenience. We highly recommend them.
