1. What is Geothermal Heat Pump Capacity?

Geothermal heat pump capacity refers to the heating or cooling output of a geothermal system, measured in tons. Proper sizing is crucial for efficient operation and optimal performance of the geothermal system.

2. How Does the Calculator Work?

The calculator uses the geothermal heat pump capacity formula:

\[ Capacity (tons) = \frac{Heating Load (BTU/h)}{12,000} \]

Where:

\( Capacity \) — Geothermal heat pump size in tons
\( Heating Load \) — Total heating requirement in BTU per hour
\( 12,000 \) — Conversion factor (1 ton = 12,000 BTU/h)

Explanation: This formula converts heating load from BTU per hour to tons, which is the standard unit for measuring geothermal heat pump capacity.

3. Importance of Proper Sizing

Details: Correct geothermal heat pump sizing ensures optimal energy efficiency, proper temperature control, extended system lifespan, and prevents issues like short cycling or inadequate heating/cooling.

4. Using the Calculator

Tips: Enter the total heating load in BTU per hour. The heating load should be determined through a professional Manual J calculation or energy audit for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is a geothermal heat pump?
A: A geothermal heat pump is a heating and cooling system that uses the earth's constant temperature to provide efficient climate control for buildings.

Q2: How is heating load determined?
A: Heating load is calculated based on building size, insulation, windows, climate zone, and other factors. Professional Manual J calculation is recommended.

Q3: What are typical geothermal system sizes?
A: Residential systems typically range from 2-6 tons, while commercial systems can be much larger depending on the building requirements.

Q4: Why is proper sizing important?
A: Oversized systems short cycle, reducing efficiency and lifespan. Undersized systems cannot maintain comfortable temperatures during extreme weather.

Q5: Should I consult a professional?
A: Yes, this calculator provides an estimate. Always consult with a qualified geothermal contractor for precise system sizing and installation.
