Although most hot water systems have target temps of 60 o C / 140 o F, when showering a temperature of between 42 o C / 107 o F and 45 o C / 113 o F is normally used. Therefore 300L of hot water at the tap may only draw 220L of hot water (at 60 o C / 140 o F) from the storage tank

  1. Solar water heaters save energy by preheating water to the conventional heater. Solar domestic hot water systems are usually designed to meet 40% to 70% of the water heating load. A back-up, conventional heater is still needed to meet 100% of the peak hot water demand generally, especially for cloudy days or for when the solar system is down.
  2. Add an optional secondary solar heating loop such as pool heat, solar home heating or hot tub. You should also up size the solar water heater to accommodate for the extra demand. As an example a 1200 square foot home with radiant floor heating and 4 persons should require a SWH-4 = SWH-1 + 3 (400/1200)
