What is the difference between air source water heater and solar energy?
Now in the market, air source water heaters and solar water heaters are relatively safe, what are the differences?The air source water heater is absolutely safe. It heats water by absorbing the heat of the air. The solar water heater heats the water by the heat in the sun. When there is no sun, it needs electric auxiliary heating, which is also dangerous.
Once the electric auxiliary heating is installed, there is bound to be a danger of electric shock. Pay special attention to the effectiveness of grounding and leakage protection during installation.
Comfort aspect
Air source water heaters can maintain constant temperature hot water for 24 hours. Solar water heaters will greatly reduce the temperature after one or two days. They can only be used for ordinary hand washing and are not hot enough for bathing.
The heat preservation effect of the heat preservation water tank of the air source water heater is much better than that of the solar energy. The main reason is that the solar heat preservation water tank has many holes connected with the glass tube, which will inevitably lead to heat loss.
Function comparison
Air source water heaters have kitchen air-conditioning functions and central hot water functions. The hot water of solar water heaters can only be used in bathrooms, and central hot water meets daily needs in life.
The air source heat pump with water circulation can double as an air-conditioner, which is especially suitable for beauty salons. It can heat water and send air-conditioning, killing two birds with one stone.
Saving comparison
The air source water heater heats 200L of water for about 2 hours. It needs 1.2~1.5 kWh a day. Solar water heaters do not require electricity when the sun is full. However, in rainy weather or at night, when enough water is needed, the heating is 0.7 kWh for 20 minutes. The power is about 2000W.
When solar energy is not hot enough in winter, it is more cost-effective to install gas-assisted heating than electric heating.
Restricted comparison
Air source water heaters are not affected by any factors during use. Solar water heaters are very affected by the weather. They cannot work on cloudy days, cannot work on rainy and snowy days, and cannot work at night, which is very restrictive.
