Rule of thumb, of course. So the space you want to cool ( 20×20=400) should be doable wih a 1 ton (12,000 BTUH) unit. But I’d bump it up to a 15,000 – 16,000 BTUH to handle the hot, humid summer heat of your area. Re: How many BTU for a 20×20 bedroom?

Then, How hot is 1000 watts?

This would be like an “average” oven temperature of 350 degrees. 700 Watts in microwave >> like cooking at 350 degrees 800 Watts >> 450 degrees 900 Watts >> 525 degrees (Self clean) 1000 Watts >> 575 degrees 1100 Watts >> 625 degrees (Blow torch!!)
