I am building my 16'x40' and was going to have 1 9x18 and (2) 5' pools in it among other tanks. With the pool being 4500gallons and each of the 5' one chiming in at 300gallons, would it make more sense just to heat the entire room. I have 7.5' cielings in it to reduce the energy costs associated with this.

Another question is if I heat the room to 82 degrees, would this necessarily make the water 82?

Thanks
 
Yes, it makes more sense to have a central heater of some sort vs. individual heaters. Room temp of 82 doesn't necessarily equate into a similar water temp. My water temps are normally lower vs ambient air in the summer & warmer in the winter. Use a thermometer & see for yourself.
 
Heat the room but have backup heating somewhere on the wet side, just in case and set them to a low background temp than can save the fishes lives.

If you systemise the setup you could run an inline pool electric heater.

I have been thinking of an indirect heat exchanger running of evacuated solar tubes on the roof and use a thermostat to stop the water overheating along with a thermal dump...just in case (always plan for the system to fail) This is expensive to set up (maybe £2000) but it would give you free heat for virtually all of the year (even in the UK)

These are used for heating water in houses all the time.
 
I have a pond in my garage and when the garage temp is close to 100 degrees I can maintain a temp of 80 degrees just by running a small 9" fan that blows across the water. You would have to get the room to around 90 degrees to see a decent water temp. You need some kind of inline heater. With that kind of water volume, I would look into a swimming pool or a hot tub heater.
 
I think water generally maintains 5 degree lower than ambient temperature.
 
There are excellent 240V heater options from industrial supply websites. If you increase your voltage you decrease your amperage and lower your costs...
 
Remember that if there is a lot of evaporation then only PURE water evaporates leaving the minerals and dissolved solids behind, this hardens the water and concentrates the bio load; therefore you need to dilute this by adding water through dilution......keep up the water changes.

To quote a wise man off this site...."The solution to pollution is dilution"
