Instant Hot Water Dispensers (Instahot) are not complicated by any means and are very useful. They consist of a miniature electric water heater and a storage tank that are both installed under the sink. Many are connected to water filters, and some models even provide cold and hot water from the sink. Water flows up the supply line into the filtration system guaranteeing the freshest water possible, from there it travels up to a 2/3 tank where it is instantly heated to around 200 degrees. While the water is heated it is replaced by fresher water and with the fast recovery system it can deliver up to 60 cups of boiling water per hour.
