When it comes to having hot water in your home and save on the electrical bill at the same time, solar hot water systems are probably the very best option. Why? These systems can be used in any climate, and sunshine is free. Plus, they are easily installed and maintained. The only real effort you have to make is to choose the model that best answers your needs, considering the climate of the region you live in.
Solar hot water systems Perth can be divided into two categories: active, and passive. The first, or passive solar water heating system, is usually less expensive, but it is also less efficient. The advantage to the passive category lies on the fact that these systems are more reliable and may have a longer life.
If your home is in an area where the outside temperatures never reach freezing levels, a direct heating system can be used. This system takes the actual water that will be used in your home and circulates it through the solar webbing, heating it and returning it to your home to be used, or stored for later use. It is the most efficient type of solar heating system and also the least expensive to implement.
On the other hand, if your home is located in a region that experiences freezing temperatures, an indirect heating unit will be the best option. This system operates much the same way as the direct heating unit but circulates a liquid through the webbing that won’t freeze when the temperature drops. The liquid is then sent through pipes to a holding tank that transfers their heat to your home’s water. It never enters into direct contact with the water, and the heat is only transferred through conduction alone. Despite being slightly less efficient and a little more expensive, it still does an excellent job of heating the water for your home cost-efficiently.
With either of these systems, it is still a good idea to have a small conventional water heater to use as a backup for the times your family requires a larger quantity o hot water, and also for the cloudy days if your home is in a northern area.
