When choosing a new water heating system for your home, it is essential to consider your home’s hot water needs. Depending on your hot water tank’s size and fuel source, you can wait up to 20 minutes for the water in your tank to reheat. A hot water recirculation system refers to a plumbing system that stores hot water produced by your conventional water heater close to the fixtures so that when you open your hot water tap, you achieve instant hot water access. On-demand hot water circulators incorporate tankless water heaters that heat water on demand without using large storage tanks. When you open an on-demand hot water tap, cold water enters your unit, and an electric element or a gas burner heats the water. As such, tankless water heaters or on-demand hot water circulators deliver an endless supply of hot water. Typically, on-demand water circulators generate hot water at a rate of between 2 up to 5 gallons per minute. However, there are bigger units that can generate 11 up to 13 gallons per minute. The larger systems are much difficult to retrofit and must be incorporated while your home is being constructed. However, even the largest gas-fired models cannot supply sufficient hot water for simultaneous, multiple uses in larger homes. For instance, running the dishwasher and taking a shower at the same time may stretch on-demand hot water systems to the limit. To solve this issue, homeowners often install two or more tankless water heaters to meet their home’s heavier demands.
