BTU Calculation Formula:
From: | To: |
Definition: This calculator converts heat pump capacity from tons to BTU per hour.
Purpose: It helps HVAC professionals and homeowners understand the heating/cooling capacity of heat pumps.
The calculator uses the formula:
Where:
Explanation: One ton of cooling capacity equals 12,000 BTU per hour, the standard conversion in HVAC.
Details: Proper BTU calculation ensures correct heat pump sizing for efficient operation and comfort.
Tips: Enter the heat pump capacity in tons. The value must be > 0.
Q1: Why is 1 ton equal to 12,000 BTU?
A: This standard comes from the amount of heat needed to melt one ton of ice in 24 hours.
Q2: Is this calculation the same for cooling and heating?
A: Yes, the conversion is the same, though heat pumps may have different heating/cooling capacities.
Q3: How do I determine my heat pump's tonnage?
A: Check the model number or nameplate - it's often indicated (e.g., 3-ton unit).
Q4: Does this account for efficiency ratings?
A: No, this is the nominal capacity. Actual output depends on SEER/HSPF ratings.
Q5: What's a typical residential heat pump size?
A: Most homes use 2-5 ton units, depending on square footage and climate.
