Solar energy cannot be used for underfloor heating.
Reasons:
1. Solar water heater is storage type and floor heating requires circulating water, so the amount of hot water is not enough.
2. The water temperature required for floor heating is low, but it requires a continuous supply of constant temperature hot water, and the heating rate of solar energy is not sufficient.
3. Solar energy produces more hot water during the day and less at night, while underfloor heating is just the opposite. It doesn't require much heat during the day, but requires more hot water at night.
4. When you experience continuous cloudy or cloudy days, more heat is needed indoors and solar energy is powerless.
1. First of all, I personally think that flat panel solar power cannotCannot be chosen in areas north of the Yangtze River, because flat panel solar power can only be applied to temperate and tropical areas. The heat collection effect of flat panel solar energy during the day is better than that of vacuum tubes. The heat collection effect is higher, but at night, the heat dissipation effect is almost the same as the heat collection effect. Therefore, it is recommended to choose vacuum tube solar power. You can consider Huangming Solar as your first choice.
2. For auxiliary energy, choose electricity. After all, it's much more convenient. Because, if we choose solar energy with evacuated tubes, electrical energy assistance will not be used too much.
