WHY HEAT MY POOL?
You bought your pool for a number of reasons like family fun, exercise, entertaining and
possibly even therapeutic reasons. However you've probably found that without heating your pool it's often too cold to enjoy. Heating your pool will allow you to enjoy it all season, perhaps all year
round, thereby increasing the return on your sizable investment.

CHOOSING THE RIGHT TYPE OF HEATING SYSTEM
There are three basic types of pool heating systems: Solar, Electric Heat Pump, and Gas (Natural or Lp/Propane). The best system for your pool is determined by numerous factors including your needs, desires, budget and physical layout of the pool and house. The answers to many of these questions are discussed in detail in the section Pool Heating Options & FAQ.

HOW DOES A HEAT PUMP WORK?
Heat Pumps utilize the sun's free heat by collecting and absorbing energy from the
outside air.
This energy is then compressed and transfered to the pool water. Your existing pool pump circulates the water through the heater, usually next to the pool equipment, and warms the pool. The pump timer is set to operate during daylight hours, usually 9am to 5pm.

The unit contains a fan that draws in outside air and directs it over the surface of the EVAPORATOR (energy collector). The liquid
refridgerant within the EVAPORATOR coil absorbs the heat from the outside air and the refridgerant becomes a gas.
The warm gas in the coil passes through the COMPRESSOR concentrating and increasing the heat to form a very hot gas which then passes to the
CONDENSER (water heat exchanger). It is here that the heat exchange occurs as the hot gas gives up heat to the cooler swimming pool water circulating through the coil.
The pool water becomes warmer, and the hot gas - colling as it flows through the CONDENSER coil - returns to its liquid form and, after passing on
through the EXPANSION VALVE, the whole process begins again. |
