Solar water heaters are a cost-effective way to heat water, making these systems a great choice for homeowners looking to save money. Basically, there are two different types of solar water heaters. The first is a stand alone heater that provides all the hot water for your home. The second is used as a pre-heater to heat the water coming into your existing water heater. The main difference in the two types is that a stand alone heater will usually have a reservoir to store the heated water and the pre-heater uses the existing water heater as a reservoir.
