HVAC BTU Calculator vs Sump Pump Sizing Calculator

Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.

Construction

HVAC BTU Calculator

Estimates the BTU per hour needed to heat or cool a room based on its size, ceiling height, and insulation quality. Use it to size an air conditioner, heat pump, or furnace before purchasing.

Answers
BTU Required (BTU/hr)
Inputs
Room Area, Ceiling Height, Insulation Quality
Plumbing

Sump Pump Sizing Calculator

Determine the minimum sump pump capacity (GPH) needed to protect your basement given its area, local peak rainfall, soil drainage, and discharge lift height. Use it before purchasing a pump or when upgrading an undersized unit.

Answers
Required Pump Capacity (GPM)
Inputs
Basement Area, Maximum Rainfall Rate, Vertical Lift Height, Soil Drainage
