HEATING TIPS

Heating in Cooler Weather...

Late night and early morning, generally being the coolest times of the day, are least

efficient for heating. For most efficient heating operation, heat pumps should be

timed to operate during the warmest, daylight portions of the day. Please set water

pump and heat pump controls accordingly.

Pool/Spa Blankets

A "solar" blanket will significantly reduce your heating bills. Check with the in-

stalling dealer to see if your heat pump was sized to be used in conjunction with

a blanket. Blanketed pools will typically lose only 3 - 4° of heat per night versus

8 - 10° overnight with an un-blanketed pool. Reductions of 40-60% on heating

bills can be achieved by using blankets.

WARNING !

Failure to heed the following may result in

permanent injury or death.

Improperly used, Pool-Spa blankets can become a drowning risk to people

and pets. Blankets are not safety covers. They are not designed to support

the weight of a person or pet. Never enter a pool until the blanket is completely

removed (under no circumstances should anyone swim under the blanket).

Follow all safety recommendations of the blanket manufacturer.

Pool and Spa Combination Heating...

Everything stated for heating a pool applies for heating a spa—only the volume of

water being heated is different. Your heat pump comes equipped with two thermo-

stats. One thermostat is for the pool and the other is for the spa. Simply position the

pool and spa isolation valves as directed by your installer; select the appropriate

thermostat (pool or spa), whichever you are heating, and with electrical power and

water flow supplied to the heater, the water will be maintained at set point.

Spa Heating & Spa Setback Option

Air blowing into your spa, while it is being brought to temperature, will very

often neutralize or partially counteract the heat being put into the spa by the

heater; this added heat loss equates to increased time to bring your spa to desired

temperature. When heating a spa, be sure to turn off the air blower. Air induced

through the spa jets should also be eliminated, during warm-up, whenever pos-

sible.

If your heater is being used to only heat a spa, the POOL thermostat can be used as

a setback control: simply set the pool control at a point 10-15º F below desired spa

heat temperature and select the pool thermostat. This method allows the spa–when

not in use–to be held at a heated temperature, but somewhat lower than normal spa-

use temperature. One would want to blanket the spa if using this setback method.

Using spa setback will result in reduced warm up periods over full, cold starts.

HEATER CONTROLS
