Abstract

Due to increasing energy costs, solar water heating is becoming increasingly popular. In a residential setting, solar water heaters are typically capable of saving 200kWh/month. A solar water heater requires a capital investment of at least R14 000. The type of solar heater best suited for your purpose is determined by several factors: available solar radiation (lower radiation areas will require larger solar collectors); differences between day and night temperatures; the amount of water you need to heat; and the possibility of frost or freezing.
