Living in Stirling, Ontario where I installed an in ground, 19' by 36' kidney shaped, Did all the work myself and saved a great deal of money although it was more work than I planned on. Hayward pump and filter with Titan 2 heat pump.
Seems to me that the heat pump is heating the pool more slowly every year. Got it up and running three days ago and the initial temperature was 50C this morning it's 73C....... so it is working however sloooooowly.
Also the flo switch seems to have packed it in. Couldn't get the flo switch to let the pump turn on no matter where I set the calibration. So I made a jumper and shorted the two wires leaving the switch and that got it running.
I'll have to get a pro in to service this thing but I'm wondering if anyone has similar experiences with heat pumps
