Swimming PoolHeat Pumps

The Certikin range of Calorex heat pumps are specifically designed

for swimming pool heating. Heat pumps are recognized as the most

sustainable way to economically heat swimming pool water and

with a Calorex heat pump you will save on operating costs and

reduce your carbon footprint. Calorex Pro-Pac heat pumps are

available for both outdoor pool usage, or for indoor pools to

enhance the enjoyment of your pool.

Why CalorexCalorex are pioneers in the development of heat pumps and have

proven performance and reliability for over 30 years. The products

are specifically designed for use in swimming pools using the most

modern technology and Calorex is approved under ISO 9001

version 2000.

Why A Heat Pump?The heat pump is now recognised as the most environmentally

friendly method of heating and considering the advantages below it

is easy to see why.

• Up to 400% operating cost and carbon saving against direct

electric heaters

• Up to 34% operating cost saving against fossil fuel boilers

• Up to 50% carbon saving against fossil fuel boilers

Product Features• Titanium heat exchangers

• Fully automatic

• Digital controls

• Quiet in operation

• Requires very little regular maintenance

• No fumes

• Kind to the environment

• Economical to run

• Can heat public or private pools to 35OC

• Easy to retrofit to existing swimming pool systems

Heat pumps simply use the free and natural energy in the air and

transfer it efficiently to pool water heating whilst respecting the

environment. By careful design a Calorex heat pump is capable of

providing your pool with up to five units of absorbed heat for every

one unit paid for.

The Challenge: To provide a

solution to pool water heating

which is reliable and economical,

regardless of ambient air

temperature and location.

OUTDOOR HEAT PUMPS SIZING CHARTS

Note: The sizing graphs shown onthis page assume the following UKconditions:

* The entire pool is constructedin-ground

• Ground water level is below poolconstruction.

• Floating heat retention cover isused 20 hrs per day.

• Average depth of water@1.3metres.

Pool surface area refers to thetotal water area (eg inclusive ofRoman ends / protruding steps /deck-level drains).

For sizing of equipment outside ofthese design parameters pleaseconsult the technical design team.

Conversion FactorTo convert from sq. ft to sq.mmultiply by 0.0929.

To convert from sq.m tosq.ft divide by 0.0929.

Roman End surface areas:6’ = 1.31 sq.m8’ = 2.33 sq.m10’ = 3.65 sq.m12’ = 5.25 sq.m
