Ground radiant heating system
The system consists of three parts: heating cable, temperature sensor (temperature control probe) and temperature controller. For the convenience of installation, the manufacturer usually assembles the heating cable on the fiberglass network in advance, commonly known as "net pad heating cable" or " Heat the mat".
The most common ones for heating cables are single and double conductors. The single-conductor structure is that the cable enters from the "cold line", and the "hot line" is connected in series, and then the "cold line" is taken out. The single-conducting heating cable is characterized by "head and tail", and the head and tail are the "cold lines" to be connected to the thermostat. The double-conducting heating cable is entered by the "cold line", connected in series with the "hot line", and then returned by the "cold line" and then the cable, which is characterized by the end of the head and the end.
The thermostat is a weapon that realizes heating and temperature control and intelligent control. The thermostat mainly has a low-cost knob-type thermostat and an intelligent thermostat that can realize high and low temperature control and protection and can be programmed for 7 days and four minutes of liquid crystal display temperature and programming. This kind of thermostat can also monitor and protect the working temperature from overheating by the temperature probe connected to the working area.
Chemical fertilizers are synthetic substances that provide the necessary nutrients for healthy plant growth and development. Chemical fertilizers combine synthetic forms of the primary macronutrients for plants such as nitrogen, phosphorus and potassium, as well as a variety of micronutrients and additives. Synthetically developed fertilizers provide the benefit of having more nutrients per pound than organic fertilizers, thus reducing costs. Chemical fertilizers have many uses for the average gardener and homeowner, as well as for commercial use.
