Depending on your insulation, perhaps on a timer to use electric night units, if you are on a day/night meter.

What temp should they be needed to go up to?

[eds]

IME it's not the upper end of the temperature that was the issue - it was the lower end. I could only find a heater that goes down to 16 degrees.

If using a glass aquarium heater make sure it's potected from the koi and won't get broken by the fish or the pond user by accident.

The consequences of a broken heater are self explanatory.

[Bob Hart]

Matt is right

When Gazza used these, he had them installed in a piece of old pipe with lots of holes drilled in it, so that no Koi could bash against the actual heater.

[Gazza]

Yes you guys are correct as thats how i found out when i looked in the tank and could see glass in the bottom

So just fit some pipe and loads of holes and job done nice and safe

Do they not come with a protective casing made of plastic??? Mind did it snaps together and heater goes through the middle.

Hi Andy

In a true QT you want to be able to have full control of the heat, whatever the outside temps.

Presume this is in the garage or a shed?

Insulation and a cover will help but if you want to get to and sustain say 26 degrees in the middle of winter then you may need to think a bit bigger, maybe even up to 1kw depending on the insulation etc. Maybe a couple of 300W units may do the trick, best to get them in an area where there is some flow, U could put them in a tube and then have an airstone below pumping some water through?

Ed - would love to find a small cheap aquarium heater that has a stat that goes lower than 16 - if you see one then shout!!

Best I found was the Jaeger heater but only goes to 16. It's supposed to be very efficient too and heat a lot more water than other 300W heaters. 2 are certainly kept my QT at 16 during this recent cold snap - it's 18 now so they're not on much if at all!

Still noty got room for QT unless sell rotivator!!!! lol
