The Domestic Hot Water Options
ADVANTAGES AND BENEFITS
This is a good practical use for solar energy. The temperature is moderate, which is good for efficiency, and the solar energy will be well utilized summer and winter. Architectural restrictions are few and economic performance is very good.
The sun will shine upon the solar collectors and warms the anti-freeze solution within. The hot anti-freeze is pumped to a heat exchanger that surrounds the domestic water tank and the heat is transferred to the domestic water inside.
If oil costs $2.00 per gallon, a solar domestic hot water heater will save enough money to yield about 10% annual return on the investment (tax free). If the cost of oil goes up in the future either because of inflation or escalation, the return on the solar investment will go up as well.
