The Sunline Solar Pool & Spa Heating system is
quite simple in it's operation. Water is pumped
from the spa or swimming pool through a multi tube
solar collector, (which is generally mounted on
your house roof) and then back to the pool. As the
water passes through the solar collector it is
warmed by the sun.
A Differential Thermostat, known as a
 Solar Controller,
switches the water pump
on or off by determining the difference between
the temperature on the roof and
the temperature of the pool water.
The Solar Controller also has a temperature control feature
enabling a desired pool water temperature to be
set when there is
sufficient heat available.
All controllers have simple plug-in temperature sensors
and come with a stainless steel mounting bracket and hardware for easy
installation.
How it works?
The solar collector is positioned in a sunny area,
either on a roof, on the ground or a specially
built frame. Pool water is then pumped through the
collector using your existing pump. The water in
the collector is heated by
the sun and returned to the
pool, turning your pool into a heat sink.
You won't have to lift a finger!
Installing a fully automatic system allows you
total freedom to enjoy your pool, without having
to manually turn valves on and off. You simply add
a Sunline digital controller and circulating
pump to your system. The controller activates the
circulating pump when the difference between the
ambient temperature and the pool temperature is
higher and de-activates
it when the temperature is colder
  
Filter Pump Connection
Open diverter valve and run filter pump in the
normal way. Close the
diverter valve to send water through the solar system.
Air will be purged from
the system back to the pool. The filter pump
has excess capacity then this valve needs only to
be partially closed, allowing sufficient water to
pass through the system and the rest to pass
directly into the pool. The position
of the valve should be marked for future
reference. Sufficient water for the system is best
assessed on a sunny day.
