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 [email protected].
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.
