Drinking water safety
The water in the radiator radiator is not clean. Since the hot water is treated industrial water, it contains not only organic pollutants, but also a large number of pathogenic bacteria and industrial chemical alkaline components. If the quality of the purchased heat exchanger is not good enough, internal corrosion will cause the water in the radiator to mix with the tap water, endangering human health.
The pipes in the heat exchanger are easily ruptured after being repeatedly washed by hot water, and the hot water of the heating system and the heating system enters the low-pressure tap water network, thereby affecting the drinking water safety. In Qingdao, there was a private installation of “heater”. During the use, the hot water pressure in the radiator was higher than the tap water pressure, which caused the pipeline to rupture. The hot water in the radiator was poured into the tap water pipe to affect the drinking water in the whole community.
Affecting overall heating
This device is actually stealing heat. Such a heat exchanger transfers the heat of the heating to the tap water. Each household has a fixed number of radiators. Usually, as long as 5 tons of coal is burned, the whole building will be hot, but the installation of the heat exchanger is equivalent to an increase. With the number of radiators, 5 tons of coal can not meet the heating demand, and perhaps 8 tons of coal can provide enough heat to reach the specified standard temperature.
