PCS1 SOLAR HEATING
Solar heating depends upon weather conditions. The more sunny it is, the
more solar radiation and the more resultant heat that is available for your
swimming pool. Conventional heaters are sized to achieve a substantial gain in
pool temperature of 10-30
°
F in a 24 hour period. It is therefore typical to find
conventional fossil fuel swimming pool heaters with ratings of 150,000 to 300,000
btus per hour.
Solar heaters do not attempt to raise the poolÕs temperature by that large a
change in a single 24 hour period. A more likely scenario is that it will take two
weeks for your solar heater to raise your pool temperature to the desired level. Once
this is reach, the solar heater works daily to maintain the temperature by replacing
the lost heat with new solar derived heat.
The difference in heating techniques can be thought of as pulse heating and
constant heating. Solar heaters are constant heaters and are therefore rated lower.
Typical ratings of solar heaters are from 35,000 to 60,000 btus per hour for residential
swimming pools. Heat pumps for swimming pools are rated similar to solar heaters
and are also designed to provide a continuous supply of heat to the pool.
The PCS1 behaves just like a solar panel system in that it will bring the pool
up to temperature over a two week period and then work to keep it there.
Obviously, if you have poor weather, the performance of the PCS1, like solar panel
heaters, will be poorer than if you have good sunny weather. Other factors will
influence the availability of pool heat and these are described later in the ÒCommon
QuestionsÓ section of the manual. This would include color of roof, etc.
