A NEW POOL HEATING SYSTEM
The PCS1 (Pool Convection System One) exchanges free solar heat from attics into swimming pools. Pools are heated for a fraction of the cost one would ordinarily expect.
NO FOSSIL FUELS, NO CFC CHEMICALS
The PCS1 will save you over 90% of the cost to heat by natural gas or heat pump. And it will heat without burning any fossil fuels or using any CFC chemicals. The bottom line is a warm pool without hot bills ! You can heat your swimming pool for around $10 per month.
NO SOLAR PANELS
The PCS1 derives its heat source from solar energy.
But, the PCS1 does not have any of the problems associated with solar panel
systems. Why ? Because the PCS1 is a heat exchanger that is installed in
the attic. It does not use solar panels.
You won’t see any ugly solar panels on your roof
line !
FAST PAYBACK
PCS1 provides low cost solar derived heat. At the same time it removes the ceiling heat and cools your home. Therefore, it pays for itself in saved pool heating and house cooling costs.
DESCRIPTION OF OPERATION
Solar radiation bombards the house’s roof structure throughout the day. The roof functions as a "solar collector". Solar radiation reaches the attic through a process called "conduction". The attic functions as a storage and heat transfer area. The PCS1 is physically located inside the attic and transfers this solar radiation from the attic air into the swimming pool’s water through a process called "forced air convection".
FULL AUTOMATIC OPERATION
Is achieved with the optional LX-220 control. When the attic is 4-5 deg C. hotter than the pool and the pool needs heat, the LX-220 automatically routes water up the PCS1 and turns it on. It can even synchronize the pool’s pump by turning it on at the same time.
BASIC OPERATING PRINCIPLES OF PCS1
The process :
The roof acts as a massive solar collector.
