Question

write the effect of gas on solar water heater.

Answer 1

Heating water is very expensive as it requires a huge amount of energy. It is believed that 18% of domestic energy is used to heat water.  In most homes and businesses this energy is generated from fossil fuels – gas and oil.  Most modern domestic boilers will run on gas and heat water on demand. But many people still heat their water using electricity which is the most expensive way to heat water.

Domestically, life would be pretty miserable without hot water, and in some manufacturing businesses, hot water is the lifeblood. We can try and save energy by implementing some lifestyle changes to use less hot water (for example, running less full baths, using thermostats on our heating system more efficiently), but in the 21st Century, we all want hot water on tap.

Solar water heating systems are a great way to reduce energy costs associated with heating water. Rather than relying on fossil fuels, there is another option and that is to use solar energy. In the case of solar thermal panels, the sun’s energy is used to heat water which is stored in a hot water tank and drawn on when required. Usually there is an immersion heater or additional boiler for back-up which can heat the water to the temperature you want in the winter or provide additional water in the summer.
