Solar Water Heating Project

Description of Solar Water Heating Project:
Exactly, solar water heating project is a large solar heating system that provides hot water from an array of solar collectors. It consists of a solar collecting system, a water storage system, a control system and a pump system. The working principle of the solar water heating project is similar to that for the solar domestic hot water system. It\'s just like a large central heating system.

Application of Solar Water Heating Project:
Solar water heating project can meet the need for large quantities of hot water by factories, hospitals, hotels, schools, etc.

Features of Solar Water Heating Project:
1. Solar water heating project is to supply hot water collectively, whose performance is like the central air-conditioning system;
2. Take solar radiation as the heat energy, energy saving is up to 80%;
3. Reduce the emission of greenhouse gas; the system is environment-friendly;
4. Combine with the auxiliary heating system to supply hot water all day round;
5. Constant temperature controlling guarantee hot water supply at any time;
6. Overheat protection, lightning protection, wind-resistance, reliability and safety;
7. Design according to the building style and hot water demand.

Note: 1. The system heat 20 tons water from 10 to 45, the total energy consumption is 3106kJ.
2. Taken advantage of the solar energy for about 305 days all year round.
3. The data mentioned above are counted in terms of the China commodity prices(factor of rise of the prices is considered)
