Describe whether there is a need for an expansion tank in a solar-energy-heated water heating system.  Support your position describing why or why not there is a need for the solar tank.

Solution

There is definitely a need for an expansion of solar energy heated water heating system. The most significant factor would be - they are cost effective. Electrical water heaters which consume a huge amount of energy to produce heat but the energy consumed by solar heaters is free - the sun.

Solar heating systems are cost-effective in cold climate where good solar resources are available. Heating your own home can greatly reduce your fuel bills. Sun is free and abundant source of energy on earth that can taken advantage of by offsetting your own solar water heating system at home. More solar energy hits the earth in an hour than it is being utilized in an entire year. If you are going to make estimation in terms of money on the amount of electricity we use in a day, the amount of propane that goes off every day, and the amount of oil required to generate our machines, it might take days to do it. Maybe years. Solar water heating system is the best cost-effective and conventional way to harness the solar energy and protect yourself from the rising fuel prices, be it a gas or electricity. Not only it provides you clean energy to heat the water, safety from bathrooms accidents from electrical water heaters, low maintenance cost, and saves space as well as these are installed on rooftops.

The energy spent on the manufacturing and installation of solar water heating system is recouped in about a year while the payback time of the system varies from a few months to 3 years. The cost of damage by pollutants to the solar water heating systems and environment is negligible compared to the devices using electricity or any kind of fuel. The solar water heating systems and other devices based on the solar energy offer significant protection to the rising fuel prices, environment and can be employed whenever and wherever possible to achieve a sustainable future.
