Solar Heaters - Economical and Environmentally Friendly Heating
Untitled Document
Solar heaters are economical and environmentally friendly. Think
about it - not electricity or propane needed, you basically don't
pay for anything except the unit itself. But are there any disadvantages?
Solar heat travels to Earth through space via photons, or “packets”
of energy. Our Earth’s atmosphere and clouds absorb much of
this heat, and the energy varies with the time of day and the season.
1.4 kilowatts per square meter is considered to be the "solar
constant" any substantial change in this wattage would alter
or even end life on Earth.
HOT TUB HEATERS OPTIONS
There are three types available depending on the fuel they use.
You can get electrical, gas, and wood burning hot tub heaters. Each
of these kinds has its advantages and drawbacks. Hence, it is important
to know about each kind in comparison with others before selecting

There is no reason why solar energy should not be used instead
of being wasted. Primarily, we can tap into solar power stored in
water by directing the flowing water through turbines, thus creating
hydroelectric power. Since plants are living solar heaters via the
process of photosynthesis, we can use a plant’s stored solar
energy through natural fuels such as wood, alcohol and methane.
The magic of solar heaters
To make solar energy work for us, we’ve devised two ways
of capturing and using this source of power. “Flat plate collectors”
and “concentrating collectors” need large surfaces exposed
to the sun to create solar heaters of any purpose. For example,
to use the sun’s energy to power a home solar heater for one
day requires a collector surface as big as a two-car garage. And
of course solar heaters work best in arias with a lot of sunlight.
Flat plate collectors are just that: flat, thin boxes with transparent
covers that are mounted on rooftops facing the sun. To empower solar
heaters, the sun’s heat absorbs into the plate and heats either
air or water in tubes running within the collector. This type of
solar heater is an excellent, predictable way of heating water or
a structure, where collectors are concentrated in the roof.
Industrial solar heaters
For many industrial heat requirements, flat plate collectors aren’t
sufficient. Concentrating collectors in large areas provide much
more efficient solar heaters. These collectors actually move to
follow the sun, unlike fixed flat plate collectors. They also power
solar heaters by using curved mirrors with aluminum or silver reflecting
surfaces that gather much more of the sun’s energy than flat
plates.
The future of solar heaters is exciting indeed! As we grow more
proficient in using the sun as an energy source, we could eliminate
the need for gasoline-powered automobiles. We could also generate
solar heaters on a large scale. Solar heaters have a great future
- unlike all other energy sources, they don't do any harm to the
environment. If solar heaters were used more widely, we would have
much less pollution problems in the big cities.
