OUTDOOR HEAT PUMPS SIZING CHARTS

For Domestic PoolsNote: The sizing graphs shown on this page assume thefollowing UK conditions:

• The entire pool is constructed in-ground

• Ground water level is below pool construction

• Floating heat retention cover is used 20 hrs per day

• Average depth of water @1.3metres

• Sheltered location

Pool surface area refers to the total water area (eginclusive of Roman ends / protruding steps / deck-level drains).

For sizing of equipment outside of these designparameters please consult the technical design team.

Conversion Factor- To convert from sq. ft to sq.mmultiply by 0.0929.

To convert from sq.m to sq.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
