And 12K btu is about equal to 1 ton.
4K Btu is perfect.
If there vented/air cooled, then shoot for at least 2k btu for every 1000 watt light.
6K btu is perfect.
1,000 watt light.

The second equation is used to turn raw power into BTU.
However, motors and pumps tend to have a bad power factor, so watts is not volts * amps deltaT, this must be the outside water loop.
For watt-hours.

1500 watts = 1500 watts forever.
You tagged it.
