Heating Water using Solar Power

When you think about it  we should be able to use the massive amounts of power from the sun not just for heating domestic hot water but for much more of our energy needs, including electricity generation.  Scientists have been working hard to make this feasible but it is far from being completed and we all have our part to play in this, however small.

Designing a solar power heated home is a fine idea as it shows that you are preserving our natural resources for future generations.  It also means that regular increases in the cost of electricity and gas won’t affect you as much because you are taking advantage of a renewable energy source that won’t harm the environment.

Solar heating can be used to complement your existing hot water heating system or even to replace it completely if you so desire.

Once you choose to change your main power supply over to solar energy for hot water heating you will need to make some adjustments to the equipment that use the power source.  When you use solar power to heat up your water you could realize that you will have to get a solar powered water heater to be able to do that.

With a bit of luck, you may be able to save money by making adjustments to your current hot water heating system but no matter measures you decide on to turn it into solar power it will be worthwhile, financially and environmentally.

There are several different methods to heat your water by means of solar power. You can even make your own solar power source to do this. Heating water using solar power will occur before the water enters your home as it flows through the solar heating equipment . To be able to heat your water effectively you will need to have both a solar collector and a water storage tank of some kind.

A flat plate collector is the most conventional type of solar power collector. It’s designed as a slim, flat rectangular box that has a transparent cover and will carry the liquid to be heated.  This liquid might be the water or it may include a solution such as antifreeze that will inhibit the water from freezing. As the water moves through the tubes it goes to an absorber plate that’s painted black to absorb the heat from the sun.

As the sun’s rays heat up the collector this in turn will heat the fluid that passes through the tubes. Once the water passes through the tubes it then goes into the storage tank which will hold  the solar-heated water.  This storage tank will be well insulated so the water will retain the heat for a longer time.  The heated water held in this tank can be used by the home when needed.

Solar water heating systems are divided into two groups – active and passive.  When the heating systems are active, it means that they use  pumps or some other mechanical device to transfer the water between the flat plate collector and the storage tank.  Active water heating is the most common as it is quicker and more efficient.

The passive system relies on gravity to supply the water from the flat plate collector to the storage tank.  This can be slow at times and may not be enough enough to keep up with the demand.  Both ways work so it will be your own preference as to which one is more apt for your situation.  Another thing that you want to think about is that if your flat plate collector and your storage tank is not position correctly it might be hard for gravity to feed the liquid through.

When all’s said and done, heating your water via solar power collectors can be reasonably cost-effective and can be set up with a bit of effort.  Deciding to heat your water using solar power is a rational idea and a noble way to help care for our environment.
