"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 FAQs, answered by experts

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.

Yes, a water heater can be replaced in a day and can take between two and three hours to install from start to finish. Even if you encounter extra tasks that need to be completed, the job can still be completed in one day.

Every city and state will have its own set of installation codes and laws. Some won’t require you to obtain a permit before replacing your water heater, though we recommend you do, regardless of the local codes. On the other hand, some cities and states might require secondary permits for plumbing and electrical work related to the installation. Check with a local water heater installation company and local building codes to confirm which permits are required and what the specific laws are.

A thermocouple is a pretty simple device. It simply tells the control valve if heat is present. Most water heaters can use a universal thermocouple, provided it's the correct length. Getting one that's long enough for your appliance is crucial for success. However, some water heater models require model-specific thermocouples, which is why it's essential to take your existing one to the store to find the right match.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.
