A Cost-efficient Heater

Your new pool heat pump is the most cost efficient way to heat your pool.Traditional pool heating systems like natural
gas, propane gas, oil and electric can only generate heated pool water on a dollar to dollar basis at best. In fact, the more
expensive fuels like electricity and oil return 70¢ - 80¢ of heat for every dollar spent resulting in an inefficient operating
return on investment.

How Does It Work

Heat pumps work much like an air conditioner works but only in reverse. The Zodiac heat pump has the unique ability
to capture free warmth and moisture from the surrounding air and transfer it to your pool water. It is because of this
principle that your pool heat pump may attain efficiency ratios going up to 600% or 700% in the best climactic conditions
(COP 6 to 7). Just as "miles per gallon" is an important measure in evaluating the efficiency of an automobile, COP
(Coefficiency of Performance) is the critical measure of efficiency for evaluating heat pumps.The higher the COP number,
the more efficient the heat pump. Simply said, that means for every dollar spent on electricity to power the heat pump,
you will get that dollar multiplied by the COP factor back in total dollars worth of pool heat.
As an example, the Zodiac ZHP-3216-TI with one of the higher COP's in the industry at 6.4 yields $6.40 worth of pool
heat per $1.00 invested of electricity. $1.00 x 6.4 = $6.40.

LOW MAINTENANCE

Your pool heat pump is designed for lower maintenance at a lower cost. But if you want your pool to be heated efficiently,
you must follow the advice we supply in this manual.
