Published BTU, flow requirements, electrical load and confidence — because “1/2 HP” is not a complete engineering specification.

Compare model-specific BTU/h and flow requirements before choosing by horsepower alone.

Use the database to compare published capacity and flow. Use the calculator to decide fit.
Nominal horsepower is not a complete cooling-capacity specification. Published BTU/h gives a more comparable starting point.
A thermally adequate chiller can still fail if the pump cannot maintain required flow through the real loop.
Indoor-only equipment should not be treated as outdoor-rated just because the calculator shows enough BTU.
