As a comfortable and energy-saving heating method, floor heating has attracted more and more attention. However, many people don't know how underfloor heating works. This article will take "how does the water of floor heating circulate" as the theme, and lead everyone to explore the mystery of floor heating.
First of all, let's understand the basic composition of floor heating. The floor heating system is mainly composed of heat source, water pipes, heat sinks and control systems. Among them, the water cycle is the core of the underfloor heating system.
The water circulation process of underfloor heating can be simply described as: the heat source heats the water in the water pipe, the hot water is transported to the heat sink through the water pipe, the heat sink dissipates the heat into the room, and then the cooled water returns to the heat source again for heating, thus forming a closed circulation system.
Specifically, the water cycle process of underfloor heating can be divided into the following steps:
Heat source heating: The heat source of floor heating can be gas boilers, electric boilers, air energy heat pumps, etc. The heat source heats the water to a certain temperature, usually 40-60 degrees Celsius.
Water pipe delivery: The heated water is delivered to the heat sink in each room through the water pipe. To ensure a smooth flow of water, underfloor heating systems are usually fitted with pumps.
Heat sink heat dissipation: Heat sink is usually laid under the floor or in the wall, and when hot water passes through the heat sink, the heat is transferred to the floor or wall, and then dissipated into the indoor space. This way, the whole room will be kept warm and comfortable.
Cooling water reflux: The temperature of the water after heat dissipation is reduced, and it is returned to the heat source through the reflux pipe for reheating. A control valve is usually installed on the return pipe to control the flow and temperature of the water.
To sum up, the water circulation process of floor heating is a closed circulation system, which realizes the warm and comfortable indoor heating effect through the coordinated work of heat sources, water pipes, heat sinks and control systems. Autumn and Winter Check-in Challenge
