Water Heaters questions, answered by experts

Electric water heaters do not need an attached vent, but the location of the water heater should allow for roughly 12 inches of clearance around it. This allows cool air to flow around the appliance and allows repair technicians to work on its components safely. The exact amount of clearance space required depends on your local building codes.

Professional installs conclude in mere hours, with complexity differences possibly prolonging efforts slightly. Site condition often dictates the exact duration.

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.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

If you want instant hot water and to reduce water waste while improving convenience, a hot water recirculating system is worth it, especially if you find your hot water heater is not hot enough. These systems can save thousands of gallons of water each year so you don't have to wait for hot water at faucets and showers. The upfront investment can be high, especially for systems requiring additional plumbing, but the long-term savings on water bills and added comfort make them a worthwhile upgrade.
