I know this thread has been around and developed for a long time, but I think it is time to discuss it from the perspective of building body shape, as we always do here.
In particular, at this time of year, what body shape has been targeted and achieved between early summer and late autumn as the wintering season approaches? This will narrow down the realistic options from the various methods available.

If, for example, muscular fleshing from the shoulders to the back is not achieved, as it is in our country, China and South-East Asian countries, the option of normal feeding at a heated temperature such as 18-20 degrees Celsius is reasonable, at a cost to the energy bill.

8.2 in mine at the moment, meant to be warmer tomorrow so will get the covers off for a night before the big freeze!

[davethefish1]

still at 18C will start dropping down to 16C this month.
averagely 2.5 kWh a day for heating last month (december) so about 30p a day. 12p/kWh off peak tariff.
though i did have an anomaly when i forgot to 'lock' the lid bolts and the lid blew open overnight when it was windy, needing 8kWh of electric to get back up to temp...

Theres a cold snap forecast here -3C tomorrow night....

Definately considering heating my pond!

Hi Dave, Happy New Year.
We are renewing our electric supply this year with a view to adding an ash before winter. Would ideally like to ensure a constant winter temperature of around 10 degrees. Can you set the one you have to go as low as that?
Any problems you can foresee?

the settings on my ASHP will let you set a temp as low as 8C.
but the lower your pond temperature the longer the defrosting cycle takes.
so if temps get really low it may end up in a cycle of defrosting more than it is heating, and not be able to hold the pond temp up.
if the temp drops further than the minimum set point it will throw an error code and stop working.

but these are in extreme weather conditions, and also depends on size of pond, and on model and sizing of ASHP.
as models like the thermotec inverter pro wil run down to very low temps -15C

zero point seven and all is well.

Hi Dave,
Thank you for your response.
It's driving me crazy worrying about the fish being too cold. It's 4.1 in the pond today.
As I don't have a pond window I keep checking them on the underwater cameras. If one is sitting on the bottom I then check again 10 minutes later to make sure it's moved :-(
Could you tell me more about the one you have?

[NamoAmituofo]

Happy NY all!

Pond temp dropped to 5.0 tonight and seeing the forecast for next few days I put the 600w DD heater in the filter for 24hrs on till when air temp recovers to 7 or higher next week (per forecast).

Only covering with poly sheets and the snow and ice offer some insulation. Didn’t bother to insulate the filter this year just left it exposed and plug in the DD heater. Pipes are all wrapped up though.

the fish will be fine at those temps, its the swings when it goes hot/cold that can cause problems.
they obviously enjoy being warmer, but they are very well adapted for long cold periods.

the thermotec eco pro inverter model I have isn't made any more,
there is a newer model called a neo inverter, and from what i gather the heat exchanger is very slightly smaller,
but is rated down to -7C but this also depends on humidity you have to weight up if it will manage in extreme weather.
as there are a lot of variables like your latittude and location as northern and rural areas can see temps much lower than urban southern areas.
so it's a risk and judgement call to go with heat pump not rated as low as some of the others.
but i have a back up elecro pond heater if it gets too cold for the ashp.

If you want the reccomended thermotec for koi ponds it's the inverter pro.
otherwise look at a cheaper koi pond brand ASHP like the remora.

Mine are sat at 9 degrees.Elecro heater,enclosed on three sides and double covered with an Aquosis cover.I just cant bear to see them motionless.The Elecro is suprising good value,all things considered .It did cost £27 a month the last time i metered it,but will be more now

Got this from Amazon and it seems great for the money

I thought there's a thread somewhere asking about pond thermometers but can't find it - maybe just me?
