In other words the collector was functioning more like a heat exchanger than a solar collector.
Solar attic heat exchanger.
Solar water heating systems use three types of heat exchangers.
One static vent style is the turbine vent which uses wind to power its enclosed fan all it takes is a light breeze to rotate the blades and suck heat out of the attic view example on the home.
Liquid to liquid a liquid to liquid heat exchanger uses a heat transfer fluid that circulates through the solar collector absorbs heat and then flows through a heat exchanger to transfer its heat to water in a storage tank.
As a bi product the exchanger is blowing air conditioning into your home cooling it down.
Please note that the pcs3 solar pool heater heat exchanger can heat and also cool your swimming pool.
I think since you will save heating your pool they justify charging such a high price for the attic heat.
You supply all the required valves and electronic controls to either operate it manually or to automate it.
Solarattic pcs2 pool convection system solar heat exchanger.
Has engineered the pool convection system 2 to heat your swimming pool using your attic and roof as a source of free energy.
And if you operate it manually you might get mixed results.
Solarattic solar pool heater model pcs3 provides solar pool heating without the use of solar roof panels by using the attic and roof as the solar pool heating heat collector and a heat exchanger is placed inside the attic to transfer this free solar heat energy into the swimming pool.
Heat transfer fluids such as antifreeze protect the solar collector from freezing in cold weather.
This solar pool heater cools the home as it heats the pool.
At a mrsp of only 2995 this fourth generation of solar pool heaters is the most cost effective way to heat a swimming pool.
When experimenting with water heating solar collectors in the attic i saw apparent efficiencies on the order of 150 to 200 ie the amount of heat absorbed by the collector was 1 5 to 2 times the amount of solar energy that actually hit the panel.
This is the pcs3 solar pool heater heat exchanger sold by itself.
Simply stated a solarattic pool heater is a heat exchanger mounted in or near your attic or garage that takes the heat from your attic or garage to heat your pool.
When your attic gets hot the solarattic swimming pool heater can add six weeks on to each end of your swimming season and can raise your pool temperature 10 15 degrees.
Solar pool heating is taken to the next level with the new fourth generation solar pool heater that eliminates roof mounted solar panels and cools your home as it heats your pool.
