The advantage of using solar water heating system
Why a 300L copper coil solar water heater?
There are several reasons that make thermosiphon 300L copper coil solar water heater an attractive and popular alternative:
Economic aspect: Initially it is more expensive to buy a 300L copper coil solar water heater than a conventional gas heater. However, the 300L copper coil solar water heater uses the sun's free energy while the conventional gas heater uses fossil gas which is not free. The accumulated expense that involves the purchase month by month of gas comes soon equal to the expense made in the purchase of the 300L copper coil solar water heater. It is estimated that the average recovery period of the money invested in the 300L copper coil solar water heater is between 1 and 3 years. Another problem is that the price of gas is constantly increasing, which causes the recovery time to be reduced.
Energy independence: Having a 300L copper coil solar water heater means having greater energy independence. We do not rely on gas or electricity companies to heat the water, so avoid the problem of price increase problems.
Ecological aspects: The ecological implication of acquiring a solar heater is also very important. If we stop combustion for water heating, we stop releasing a large amount of carbon dioxide into the atmosphere which contribute to global warming and air pollution. 300L copper coil solar water heater also takes advantage of abundant and free energy resource, such as the Sun.
