Cheapest way by far is a gas boiler. Even then your going to need a massive amount of insulation and cover it to keep the temp in and the costs down.Muske;4741998; said:Gas fired boiler is going to b needed to keep heat up on 5K gals.
Koi, goldfish, and natives don't need heat.....
For koi if it is possible always heat. It depends on what the temps go down to. The top koi keepers heat to a minimum of 10c and that goes up to 20-22c in the summer(yes they even heat then).Muske;4741998; said:Gas fired boiler is going to b needed to keep heat up on 5K gals.

A Kois immune system slows right down below 8c and is none existent below 4c. This is why people have so much trouble in the spring when the temps go up, parasites attack and the koi have no way of fighting back. That is if they get through the winter.
I've already lost one goshiki so far and the I've posted about the tancho going on a tropical holiday. Temps are around 0 to -2c on the surface.
I'm simply not going through this next year, even with temp covers on I can't get any heat to stay in.
All of the above is from a koi keeper.
