"A Plumbing Pro has been my preferred plumber in Southwest Florida since 2009. Once again they came through when my kitchen faucet started severely leaking while I was out of town, and my housesitter reported they couldn't shut off the water with the supply valves under the sink. My reliable plumber responded after my long distance call within the hour, removing and replacing the leaking faucet, along with the failed supply stops, and an old kitchen disposal. With A Plumbing Pro I consistently receive great service, and always cost effective and reliably professional plumbing work. That's why I really like this company."

"Shaddai Plumbing team is great! They are very professional, they keep their word, they complete job without delays. Great quality. We had to replace old water pipes across 2-story home and their service was great. We asked to add additional water switches to be able to switch hot/cold water on and off in separate parts of home - and they did it. Now if it will be leak or other problem - we can switch off kitchen area, or second floor without impacting other parts of our home. Highly recommended!"

"We needed a water heater replacement and Chris T., provided a detailed explanation of the new system, water heater manufacturer, installation process, and newly installed equipment. The level of detailed explanation on the invoice coupled with the home inspection paperwork is often not seen with home service companies. Will certainly hire again for plumbing services."

"Paul and his crew ( I think his name was Waldo?) did a great job. They were able to do the job immediately. They removed and installed a new water heater. The job was completed in a timely fashion and they left everything clean. There wasn't a trace of nthem being here, except for the new water heater."

Water Heaters FAQs, answered by experts

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.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.

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.

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

Gas water heaters last between eight and 12 years on average. You can help them reach their maximum lifespan with regular cleanings, maintenance, and professional checkups, though don’t hesitate to swing for a full replacement if the total cost of repairs is greater than that of purchasing and installing a new unit.
