home hot water heater for monster tank?

[wright4lfe]

a friend of mine has a large pond in his backyard and we were discussing different types of heating he could use. i don't know what he uses right now, but he bought it at a pond/koi place in westminster, ca.

i was thinking he could maybe use an electric hot water heater primarily used for heating water in a home. he has the really expensive solar panels on his roof and doesn't pay a dime for his electrical usage. in fact he regularly sells back energy to the utility company.

back on topic, could a 50-60gl water heater normally used for a home be effectively used on a 1500gl pond?

but is gas not cheaper ?

i'm sure gas is cheaper, but when you get electric for free (and are at times selling it at a profit) it might be better to go that direction. i was just wondering if they are efficent enough or if getting a heater specifically for ponds is the best way to go.

a conventional hot water heater in my opinion would not be ideal for this application. just because of how they work, they are meant to be filled with water and then heated to a desired temp, if you were circulating water threw one it would never shut off, it not very efficient.

I would be curious about using one of those instant, in line hot water heaters, most likely the temp would be to hot

You could put a mixing valve right after the instantanious water heater.

(one of my random thoughts: Why would you want a hot water heater? Is there a point to heating hot water? )

No...basically for the reason hmt321 stated. Depending on the water heater you could be expending 7600 watts of electricity and the elements were not made for continuous use.

If he's already got electric solar panels, apparently he has good sunlight how about solar panels to heat the water (works good here). Use the one that are for swimming pools.

No again, these are not made for constant use either.

You stole my line!!!

he's already got the ones for heating water for his pool. at this point he's working on a way to divert some of the water to his pond when he's not regularly using his pool...which is most of the time.

Purging the chlorine out of the pipes is going to be a bigger pain than installing another panel .

sorry but there is not enough info for a good answer

1) what are the pond dimensions ??
2) what is the desired water temp ??
3) what is the coldest outdoor temp to plan for ???

from this we can calc the btu's ( watts) needed to heat the pond.

and hence the number of watts or btu's needed for whatever type of heater is chosen.

once you know that you can go forward..........a water heater could be set up like any other heater with a thremostat on the "heat" and continous water running thru.......... but why ???

2 cents or less worth
