- Purpose
Solar water heating systems are the perfect choice for larger establishments and larger families, since they help you save water while saving a lot of energy as well. Highly efficient in their function, buying a solar water heater is one of the best steps you could take to save on your water heating bills.-Cost
Although pricier than the other systems, solar water heaters can end up saving you money and can be worth the initial high price.-Types
There are two types of solar heating systems; the FPC which is the Flat Plate Collector and the ETC which is the Evacuated Tube Collector. The FPC is made of metal, and though expensive, is more durable and has a longer life. But they need extra protection if you live in a location where the temperature goes below zero. In contrast, the ETC system is much cheaper and made of glass, so it’s a bit fragile as well. Repairing the ETC system can cost a lot if something damages it, and requires a heat exchange as well if you get salty water in your region.
