Going to heat my main pond this year.2700 gallons.It is a fibreglass tank and may possibly be able to add more depth to it next year ,by adding 1meter to the walls ,taking it to about47000 gallon ish.What heat pump would you recommend for both size's ..what brands are leading the way?????.Any advice would be good

Re heat pump email willie as he has done some training and sizeing our andy as he has them fitted on his pond

Hi,
Most people down south are using Duratech heat pumps, I have an Daikin Altherma on both house and pond, very good machines, you would probably need 6 or 7 kw for your pond this would give you a little bit of cover if things get really cold, I would strongly advise some sort of back up heating just to cover you if the temps get really low and the heat pump shuts down due to very cold weather
( -12/15c) I have had mine for 4 years now and last years winter temps were the only time I have had to use some back up heat, they cope well otherwise! Dave Collins also a form member here has some very good stats and keeps recordings of energy used ect.might be worth having a word with Dave.

Thanks guys .I see the duratech 7kw on flee bay for 995.would that be about the right price????

Hi, yip not to bad for price, should be plug and play as well, is that new ? good price if it is.

Hi Guys

Don't buy the one on ebay it's no good for Koi ponds, it shuts down at -5°C I seem to remember. Contact the seller, I and many others have bought from him, but you need the Duratech Plus 7kw. This is a better machine, and costs a bit more, and will operate down to -10°C and is still better than pure electric.

We've had temperatures this week down to -12°C and it's performed well and not cut out, holding my covered pond at +10°C easily.

Thanks again chaps.I had a quick scan ,about £1350.Not to bad.Amazing what we lot ill do to add a few centimetres .
