Most solar water heaters require a well-insulated storage tank. Solar storage tanks have an additional outlet and supply connected to and from the collector. In systems with two tanks, the solar water heater heats the water before it enters the classic water heater. In single-tank systems, the backup heater is combined with a single-tank solar tank.
Solar heating of sanitary water, ie. solar hot water systems are an ideal solution, bringing very high savings in money spent on electricity.
On average, every household consumes as much as 70-80% of electricity only for heating sanitary water, which makes financial expenses very high, considering that hot water is consumed in larger quantities every day. By installing a solar system for solar heating of sanitary water, very significant financial savings can be achieved, both on a monthly and annual basis, especially on a multi-year basis.
For tourist facilities, motels, SPA centers, especially for industrial facilities where the needs for sanitary hot water are high, very significant financial savings are achieved.
