Solar water heaters are units that can supplement or replace an existing gas or electric water heating system. Solar panels will be installed on the exterior of the house to heat the water.
"A typical solar hot water system will reduce annual energy costs by 40 to 50 percent. You can expect that a solar water heater will provide you with 1500 to 3000 kWh of energy per year, depending on your hot water usage and regional climate." - from http://www.canren.gc.ca/prod_serv/index.asp?CaId=138&PgId=1268
