In a larger home or business where the sink is located far away from your large water heater, it can take up to a minute for your water to heat up. In these cases, it’s recommended to install a point-of-use water heater. This small appliance is the best at bringing hot water to your bathroom or kitchen sink quickly. It can be installed right near the faucet it supplies, connecting directly to the plumbing, so the instant you cut on your fixture, you have hot water.
Conventional Water Heater Vs Point-of-Use
With a conventional water heater, every time you cut on the hot water, the heated water fills up the whole plumbing from the heater to the sink in use. Once you cut your water off, the heated water immediately starts cooling down. This is a waste of the energy that was used to heat it.
Point-of-use water heaters are an energy efficient choice because it cuts out the distance your water has to travel between the main water heater and the far away faucet. The water is still hot by the time it travels the pipes to your sink. You also don’t have to keep the sink running while waiting for your heated water, saving on gallons of water waste per month.
