The antifreeze and heat preservation of the solar water heater pipeline adopts a self-limiting temperature electric heating cable. It has the advantages of small starting current, fast heating speed, simple installation, and worry-free use. It is an energy-saving and environmentally friendly product.
When the user buys the solar electric heating cable, how to install it? Which installation method is best to choose? It really makes it difficult for users. In fact, the solar electric tracer is safe
Installation is very simple, as long as you master the following installation essentials, users can install it by themselves.
Installation method
1. If the diameter of the water heater pipe is greater than 3 cm, the winding installation method shall be adopted. Attach the solar electric heating cable to the pipeline and wrap it in parallel at equal distances. Note
It is intended to keep the electric heating cable as flat as possible without any discount. And fix it with aluminum foil tape or pressure-sensitive tape, and then cover it with a sealing and waterproof insulation layer.
2. The diameter of the water heater pipe is less than 3 cm (including 3 cm), and the single parallel installation method is adopted. Attach the solar electric heating cable to the pipeline and lay it in parallel.
There should be no gap between the electric heating cable and the pipeline, and it should be fixed with pressure-sensitive tape or aluminum foil tape, and then put on a thermal insulation layer with good waterproofness.
Insulation pipeline
1. The water supply pipeline of the solar water heater and the water supply pipeline are cold water to prevent the sub-zero temperature from causing the pipeline to freeze or burst;
2. The heated downspout pipe is hot water, which can maintain the temperature of the hot water, supplement the lost heat, and prevent the pipe from freezing and cracking;
Precautions
1. Do not make the electric heating cable folded or overlapped to prevent short-circuit fire and poor thermal insulation effect.
2. There is no gap between the electric heating cable and the pipeline, and the thermal insulation effect is better.
3. The end junction box (terminal junction box) of the electric heating cable has good sealing performance, and the end of the installation end should be placed outdoors; the end connected to the power supply should be placed indoors, which can prevent
Water into the electric heating cable, causing a short circuit or fire.
4. The maximum length of the solar electric heating cable is 50 meters, and a single installation should be used as much as possible; when the heating cable and the heating cable need to be connected and installed, the intermediate junction box can be used and sealed to prevent the junction box from entering the water.
5. Install leakage protection switch or air switch.
6. Please consult a technician before installation, or install under the guidance of a technician.
