Need help with heating a 720 gallon acrylic tank

[Rays of Sunshine]

I am asking this question for a fellow hobbyist. The acrylic is 1 inch thick. The tank is in the garage. Do you think 3 1500 W Titanium heaters are enough? Where do you buy the heaters in this wattage? The future plans are Amazonian fish like Peacock bass, etc...

Here is a picture of the tank:

I'd get three True-temp titanium heating system 1000w

should you run the heaters in both the summer and winter?

also would a spa heater work with a controller for temp controll?

Where is your hot water heater in relation to the tank? I'd run a "closed loop" on a thermostat and a pump to heat something that big.

the hot water heater is in the garage so that may work. can you explain more whatca mean witht he closed loop?

Are vendors that sell larger heaters. Options are inline heater, or possibly a titanium heater with a controller.
