Do both my boiler and water heater need their own expansion tank?

• <div><p>Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater. </p></div>

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: 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>.

• <div><p>Several things can void the warranty for your water heater. Many water heater manufacturers state that installing your own will void the warranty.

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet. I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."
