Thread: Ashp

Hi all
I am looking for recommendation for an ASHP for approx 2500 gallon pond. Around 1.5 mtr deep aa picture.
I will cover and stop using the blade.

Thanks in advance

My pond is also 2500 gallon.
the best ASHP is arguably a thermotec inverter pro (but they are not cheap). work well down to low sub zero temps, and you would want a 9kw model.

but i manage fine with a slightly over sized 12kw thermotec inverter eco.(the larger heat exchanger size makes a big difference in low temperatures.)

inverter ASHP's are more economical than on/off ASHP's by a large margin if not run at full pelt.
if you undersize an inverter ASHP it will have to work at maximum power, and they only get better COP at 60% power or less.

Thanks for that. Actually oversizing might be a good plan as when I get around to it I want to increase the pond to around 4000 gallons

my 12kw ASHP can run up to 1800watts under high load,though i've never seen it anywhere near that high (i have a hard wired energy monitor)
but it runs at 400 - 700 watts usually.

Thanks again - that's all great info.
It sounds like a 12kw will be the choice, giving me a little room for a bigger pond later.
Nice tidy installation by the way
