Reliable.
With current technology, solar energy for home heating is technically reliable. But the biggest problem is that the cost is too high! For example, if the heating area of your house is 100 square meters, you need at least 4 kilowatts of power to achieve the necessary thermal effect.
At present, the cost of a solar photovoltaic power generation device in kilowatts is 10,000 yuan, and 4 kilowatts requires an investment of 40,000 yuan. Most importantly, the most fatal flaw of solar power generation is that it immediately stops producing electricity when there is no sun, and the long winter nights are exactly the time where energy is most needed. Therefore, a complete technical solution requires a set of high-capacity battery packs, several additional kilowatts of solar panelsires to power (charge) the batteries in the battery pack and use the energy from the batteries for heating at night when electricity cannot be generated. .
Two situations: 1. The wires are in poor contact and need to be repaired.
2 The electric water tank heater is broken and requires professional service personnel to repair and replace it. Because damage to electric heating may cause some water contamination, so for the safety and health of your family, I hope you can find a professional team to test as soon as possible. Hope they can help you!
