Thread: Heat Pump Sizing

Hi Folks

Based on your experiences , what is the ideal size ASHP for a 2500 gallon pond ?

I`m looking at the Thermotec Inverter range and the sizing they give says 9KW should be fine , but wondering if the 12KW would be more economical and quieter

What do you think ?

I run a 12Kw Thermotec Invertor on a 3000 gallon pond and its spot on. Never had an issue with it. Go with the bigger option if you can.

I have a 12kw thermotec inverter on 2500 gallons.
you need to size it for the worst conditions in winter not the the best in summer.

as it's an inverter it will run much more,up to 5000 gallons, but it is more economical at lower power.
mine generally runs at 500 to 700 watts. for a few hours a day actual power wattage.
you get increased COP at less than 60% output and best COP at 25% of maxiumum output

Thanks Dave . So worth spending the extra to save on running costs . Makes sense .
