SOLAR ENERGY SOLAR WATER HEATING HARVESTING THE SUN

SOLAR ENERGY SOLAR WATER HEATING. HARVESTING THE SUN POWER TO YOUR ADVANTAGE.

MIKE SIMMONDS INSTALLATION MIKE’S BIG HOUSE NEEDED TWO COLLECTERS. WHY?

HEATING WATER COSTS IT NEEDS 1. 163 WATTS TO HEAT 1 LITRE OF WATER THROUGH 1 DEGREE CENTIGRADE. THEREFORE IT COSTS 8 CENTS TO BOIL THE WATER FOR, 4 CUPS OF TEA OR 3 MUGS OF COFFEE. IF WE MULTIPLY THIS AMOUNT UP , IT MEANS THAT IT COSTS R 7. 12 TO HEAT A 150 LITRE GEYSER ONCE.

HOW IT WORKS • (1) THE PLUMBING AND SOLAR PUMP. • (2) CONTROL PANEL. • (3) SAVINGS. • (4) THE COST. • (5) INVESTMENT.

CONTROL PANEL THIS DEVICE IS A TIMER AND THERMOSTAT THAT COTROLS THE ELEMENT IN THE GEYSER.

HEAT LOSSES • • To get SABS approval a 150 litre geyser may lose 2. 5 Kw of heat. The first metre of 22 mm copper piping attached to each side of geyser will lose 55 w of heat constantly, when the temperature differential is 60 degrees, until your geyser gets cold. That is the same amount of power as having a 100 w bulb burning in your ceiling space 24 hours a day. Geyser heat loss 2. 5 Kw X 1. 16 X 87 cents = R 2. 52 Piping heat loss 180 w X 1. 16 x 12 X 87 cents = R 2. 18 Totally unused, the geyser costs R 4. 70 per day in electricity. Therefore, R 141. 00 per month. This has to be maintained by using electricity, so you constantly have hot water. This is why it is thought that a geyser accounts for about 40% of your account. There are ways of mitigating these losses and heating water without using electricity and the most cost effective is converting your geyser into a solar geyser.
