3. Uses and advantages
What is the use of Ketanli household hot water circulation machine?
To put it simply, after using this thing, it is the hot water faucet farthest from the kitchen water heater. , there is no need to wait for one to three minutes for hot water to come, but it can be heated immediately without waiting. Because of the regulations of some gas companies, gas water heaters can only be installed in the kitchen, so they must be at a certain distance from each bathroom. This distance ranges from more than ten meters to tens of meters (referring to the length of the hot water pipe, not a straight line distance). Therefore, if an average household only installs one gas water heater, over such a long distance, after the hot water faucet farthest from the kitchen is opened, it will take as little as tens of seconds to as slow as one or two minutes to drain away. In a villa or loft, it may take three to three seconds. Use more than 100% cold water before adding hot water slowly. This is a huge waste and not environmentally friendly.
In order to solve the problem of slow hot water coming, a variety of methods have emerged. For example, some students installed an electric water heater in the farthest bathroom. This method is good, but the electric water heater needs to continue to consume electricity, and its capacity is limited. If there are many people in the family who want to take a bath, they need to wait for the next boiler to heat up the water before continuing. If a family has a large bathtub, even For example, some students like to use a small kitchen treasure to get a liter of hot water from an electric water heater in one bathtub. We know that there are two types of small kitchen appliances. One is a model with very small power, which can only be used to wash hands, and only stores a small amount of hot water in a small water tank. This type of small kitchen appliance is equivalent to a small electric water heater, and the other is a large-scale model. Xiaochubao can have a large capacity of hot water that can be used, and it can be heated immediately, but the power consumption is astonishing and very scary. Another one is what I am talking about (Cotanley hot water circulation system). The Cotanley hot water circulation system is comfortable, environmentally friendly, and more importantly, saves money and is safe.
