Do you ever find yourself wondering how to get hot water faster? In the chilly winter months, waiting for the tap to deliver hot water can seem like an eternity. But you may be surprised to learn that, even with a standard tank water heater, you can have instant hot water in your home — or something very close to it. Let's explore your options for getting instant hot water at home.
Hot Water Recirculation Pump
One way to instantly get hot water is a hot water recirculation pump. This innovative device delivers hot water to your faucet without the wait. Here’s how it works.
When you turn off the hot water tap in most homes, the hot water remaining in the pipes eventually cools down. When you reopen the tap, you drain that cooled water until a fresh supply of hot water reaches the faucet. The process can take several minutes and can waste a significant amount of water, heat energy and time.
With a recirculation or booster pump mounted near your faucet, the hot water that has cooled is sent back to your water heater and quickly replaced with a fresh supply of hot water. Now, when you turn on the hot water tap, you get near-instantaneous hot water. Recirculation pump-equipped plumbing systems can reduce your hot water wait times by between 60 and 80 percent.
A variation of the faucet recirculation pump is the water heater-mounted unit. These models contain a 120-volt pump and a timer that is connected to the hot water line. At preset times, the recirculation pump turns on (using about the same power as a 25-watt lightbulb) and keeps the hot water circulating, making it immediately available at the tap.
Finally, electronic recirculation pumps also rely on an electric pump. However, these models add digital controls and a thermostat-controlled zone valve to achieve peak efficiency. Electronic recirculation pumps can be activated by a push button, remote control or even a motion detector.
