Water Heaters questions, answered by experts

While many older homes don’t need hot water heater expansion tanks, they’re necessary in most newer homes and are required by building codes. These tanks are required by code in areas where there are backflow preventers or pressure regulators on the incoming water pipe between the public water pipes and the water heater. However, tankless water heaters don’t require expansion tanks.

Unless you have previous plumbing experience or extensive experience with water heaters, you should avoid replacing your electric water heater yourself. 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.

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.

Examples include gas stoves, ovens, and water heaters. Confirm with your provider for specific items.

A water heater is one of the heaviest hitters in your home, and it needs as much power as possible to help it run efficiently and effectively.

Your water heater should be on its own dedicated circuit breaker, with no other power sources running to it. This is required to meet the National Electric Code–and to ensure it runs as efficiently as possible.
