High Efficiency vs. Standard Water Heaters | Reliable Water
Dec 21, 2016 · Whether you own a restaurant, hotel, apartment building, or any application that requires a great deal of hot water, your decision to purchase high-efficiency or standard hot water equipment should be an informed choice. Let’s Start with Some Basics: Tank-type Water Heaters vs Tank-less
A water heater is a storage tank that, yes, heats water. The heat is either produced by burning gas or by using electricity. A standard water heater will heat the water and then keep it at that temperature until the water is used, either for a warm shower, the washer loaded with towels, or any other hot water need. As the hot water leaves the
With a tank-type water heater, hot water is sent out from the heater to your faucet or appliance.As the hot water sets in the pipe waiting to be used, it cools off. When you turn on the hot water faucet, all the cooled off water has to be displaced with fresh hot water from the water heater.
