"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."

Water Heaters questions, answered by experts

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

Yes, this would be an appropriate choice. In order to comply with the National Electric Code’s rules, you'll need to install a circuit breaker that's 125% larger than the intended load. In this case, you'll multiply 30 amps by 1.25 to find the necessary breaker size. Plugging that equation in for your 30-amp water heater will leave you with a 37.6-amp breaker. If your current water heater keeps tripping the breaker, it might be time to talk to a plumber or electrician about upgrading your water heater's setup.

Replacing facilitates energy savings, decreases repair frequency, and aligns with modern safety regulations, maximizing safety.

The amount of time it takes to replace an electric water heater will depend on the skill level of the individual who is replacing it. For example, if you replace it yourself–and you don’t have much experience–you can expect the project to take a full day. 

However, if you have a certified plumber or water heater contractor install your new water heater, it can take as little as 2 to 3 hours.

If your water heater continues to have issues, you may wonder how long an electric water heat lasts. On average, these units last between 10 to 15 years. Following a proper maintenance schedule can help the water heater live to the end of its average lifespan or longer.
