100= 4400% EFFICIENT. In other words, the PCS1 has ten times the efficiency of the typical heat
pump and 44 times the efficiency of electric resistance heaters.
16. How does the system really work?
The roof functions as a "massive solar collector"---collecting solar heat. The attic functions as a
heat storage and transfer device---storing and transferring solar heat. And, the PCS1 functions as an
"exchanger" that exchanges the heat from the attic into the pool. This is a continuous solar process.
17. What's the worse that can happen with a conventional heater's operating costs?
The kids can turn it up to maximum and run up hundreds of dollars in energy bills while you are
away!
18. What's the worse that can happen with the PCS1 heater's operating costs?
On a cloudy and cold day, you won't get much heat. You will never get a high energy bill!
19. What are the optimum installation conditions?
A non dusty environment; a non corrosive atmosphere; proper Ph chemical balance between 7.2
and 7.6; automatic chlorine dispensing to keep levels below 3 parts per million or the use of a
nonchlorine alternative; a water flow rate of 45-55 GPM; black roof; sunny roof; sunny pool; manual
Flowreversalª; use of a pool blanket during extended periods of non use; a non salt water pool; some
shelter of the pool to minimize convection losses. Plus other factors that help minimize a pool's heat
losses.
20. Can the PCS1 heat spas?
Yes! The PCS1 has been used to heat water up to 105
°
F. SolarAttic, Inc. expects to have a
separate spa version on the market sometime in the future.
However, in the meantime, another opportunity avails itself . That is the sharing of the heat
from the attic with both the pool and a spa. This is especially true during periods of time when the
pool cannot use the heat available. During these times, the heat can be channeled 100% of the time
into the spa. A recent study showed that up to 25% of new pool installations are being installed with a
spa attached to it.
To share the heater requires the use of a Share-a-Heaterª valve. With a simple 90
°
turn of a
single valve, the spa can be heated instead of the pool. The valve allows the sharing of a single
heater and it can be automated. Share-a-Heaterª is a trademark of Mark Urban and Innovative Pool
& Spa of Tustin, California.
