Method 2: When heating in winter, the upper water pipe is hot and the lower water pipe is cold.
Method 3: At the water separator, there is a filter at the water inlet point of the upper water pipe. The pipes here are different.
Liquid circulation system, namely low-temperature hot water floor radiant heating, is a heating method that uses hot water with the temperature not higher than 60℃ as heating medium, circulates in the heating pipeline, heats the floor, and supplies heat to the room through radiation (primary) and convection (secondary) heat transfer on the ground.
superiority
1. Uniform heat dissipation: The heating principle of the floor heating system is radiation heat transfer. Compared with air conditioning, heating and other forced convection circulation hot air heating, the dust flow in the air is much smaller, which reduces the spread of harmful bacteria in the air. The indoor environment is more sanitary and clean, and the floor heating system also creatively uses the characteristics of human body temperature. Care from your feet makes you feel comfortable and makes your family feel warm.
2. Clean and healthy: the floor heating system can effectively promote blood circulation in the feet, thereby improving blood circulation in the whole body, promoting metabolism and inhibiting cardiovascular diseases; It is especially suitable for the elderly and children, and has more preventive and therapeutic effects on patients with arthritis and old cold legs. And improve the autoimmune ability to some extent.
3. Environmental protection and energy saving: Compared with the traditional convection heating mode, the floor heating system can save about 30% of energy, and the heat loss of floor heating is small during transmission, and the heat is concentrated at the height of human benefit. Even if the indoor set temperature is 2 ~ 5℃ lower than that of mobile heating mode, people can have the same warm feeling. Floor heating can fully save energy and will not produce any noise and dust, so it is a very environmentally friendly and energy-saving product.
4. Beautiful and generous: after the whole system is installed, there is no radiator and its branch pipes in the room, which invisibly increases the indoor usable area by 2% to 3%, which is not only convenient for decoration and furniture layout, but also saves tens of thousands of yuan for your house price per square meter.
5. Safe and reliable: the floor heating is resistant to acid, alkali and salt corrosion, high pressure, high temperature, infiltration, rust and pipeline scaling, smooth inside, low friction, good water quality, non-toxic and environmental protection.
6. Long service life: The service life of floor heating is more than 50 years, which is almost the same as that of buildings, greatly reducing the troubles caused by radiator running, leakage, dripping, water leakage and maintenance.
7. Efficient sound insulation: At present, precast slabs or cast-in-place slabs are widely used in domestic floors, and the sound insulation effect is poor. Going upstairs will affect the downstairs. Using floor heating to increase the insulation layer, the sound insulation effect is very good, which can reduce noise pollution, and there is no noise during heating, which is beneficial to the physical and mental health of the family.
