chaps

got a swimming pool heat pump which has a tag rating of 45,000 btu . IMG_20171120_092636[1].jpgIMG_20171101_102425[1].jpg no problem

however the compressor has failed and investigations reveal it's rated at 24,000 btu.

apart from heat of compression what am I missing?

pool temp 27c outdoor air averages 25c

TIA
