Statistics show that one adult requires 50 liters of hot water per day. On average, for hot water supply it is enough to raise the water temperature by 40 °C, which, when calculated using this formula, requires energy costs of W = 1.16 × 50 × 40 = 2.3 kW. To find out the area of the solar collector, this value must be divided by the amount of solar energy per 1 sq. m of surface at a given latitude.
Calculation of required parameters of a solar installation
Making a solar water heater with copper absorber
The proposed solar collector heats water to a temperature above 90 °C on a sunny winter day, and to 40 °C in cloudy weather. This is enough to provide the house with hot water. If you want to heat your home with solar energy, you will need several such installations.
Solar energy is ideal for operating a pump for jordan mobile database out water. The nuances of making such a unit are described here:
To make a water heater you will need:
sheet copper with a thickness of at least 0.2 mm and dimensions of 0.98×2 m;
copper tube Ø10 mm, 20 m long;
copper tube Ø22 mm, 2.5 m long;
3/4˝ thread — 2 pcs;
plug 3/4˝ — 2 pcs;
soft solder SANHA or POS-40 - 0.5 kg;
flux;
chemical reagents for blackening the absorber;
OSB board 10 mm thick;
furniture corners - 32 pcs;
basalt wool 50 mm thick;
20 mm thick heat-reflecting sheet insulation;
rail 20x30 - 10m;
door or window seal - 6 m;
window glass 4 mm thick or double glazed unit 0.98x2.01 m;
self-tapping screws;
dye.
In addition, prepare the following tools:
