Outdoor pond winterizing help in new england

[irishfan]

My friends dad has a pond, 14in deep, bout 6 foot long, 3-4 foot wide. Has some koi and goldfish in it, his winter plans fell thru and he is forced to keep them in there.

Can someone recommend a link or something to help me instruct on what to do heating wise? It gets quite cold here in the winters and I have no experience on any outdoor tanks or ponds so I am clueless as to what to suggest. Thank you

At only 14" deep, the only thing possible would be a temp. greenhouse and heat the pond. Not going to be super effecient, but will keep the fish alive.

No garage to put a stock tank in?

Space right now is pretty limited...
Thanks for the response, what kind of heaters are used for outdoor ponds in the winter, I have no idea.

The 14 in deep is the main concern.,,any more help appreciated
