Haaha oh yeah dude dont use the whole hotub just the heater pump. Haha useing the whole thing would defeat the point of haveing a nice pond to really enjoy.You my friend are a genius.... never thought of that, you have helped me out more than you could know. I would just use the pumps and run tubing instead of using the whole hot tub though.
But thats just me i guess.None of the options that you ^^ posted are cheap.
You have to think.. this kid is 14 yrs old. His PARENTS will be the ones having to pay for this. His parents would more than likely not want to have to do any of the options for what is probably "just a fish" for them.
Yeah didnt realize that. My bad.
If you want to run the water to your roof, you need a high head pumps, and they aren't cheap to run at all. So that's NOT cheap.
The pool store by me sells them for around 200 bucks. How much is it gonna cost to buy or even build at tank that big inside?
The wood burning heaters that you suggested also cost thousands. NOT cheap.
The size of the one hed need to heat a pond that size would not need a huge like the ones for a house. The small ones are fairly cheap. And wood is cheap. Really cheap or even the pellets. A bag of those can heat a house for almost amonth.
Hot water heaters have elements.. you would burn it up, and would costs hundreds a month. NOT cheap.
Are you crazy? Who has a bill that high every month? It would only run about 40 and for only 3 months. He gets a job and pays for it. Gives him good work ethhic.
There is NO cheap way what so ever.
The cheapest way would be to just buy a big enough stock tank and bring the fish inside.
No offense OP, but I think maybe having an RTC in that pond period isn't a good idea.. what happens when it gets large, and then you CANT bring it inside?
ARE YOU SERIOUS?!But thats just me i guess.
