Geothermal vs Propane Calculator
Screen the same home under geothermal and propane heating to estimate design load, seasonal delivered heat, backup share, loop flow, and propane gallons displaced without using pricing inputs.
⚙ Home and Heating Inputs
🌎 Geothermal and Propane Setup
This model compares a geothermal system handling the selected share of seasonal load against the same home heated entirely with propane. It reports energy, loop flow, backup, and emissions only.
📊 Comparison Results
Geothermal covers most of the annual load here, while propane remains useful for rare peak hours or a deliberate hybrid retrofit strategy.
🔬 Comparison Snapshot
📑 Heating Reference Tables
| Climate | Heat Rate | HDD | Geo Tons / 1k sf | Propane / 1k sf |
|---|
Geo tons per 1,000 sq ft assume average envelope, average air sealing, 70 F setpoint, and balanced geo coverage. Propane is shown as an all-propane baseline.
| Loop Type | Winter EWT | Adj COP | Flow | Best Fit |
|---|
Entering water temperature and base flow strongly influence geothermal screening results before detailed loop-field design.
| Preset Home | Area | Design Load | Geo Size | Gallons Avoided |
|---|
🛠 Practical Notes
If the selected preset or custom home shows unusually high tonnage per square foot, treat that as a shell or distribution flag first. Tightening ducts and air leakage often reduces backup share faster than upsizing equipment.
This comparison does not change how much heat the house needs. It changes which source supplies that heat, how much electricity the loop needs, and how many propane gallons remain after geothermal carries its share.
Geothermal calculator against propane help to compare the cost-effectiveness of geothermal and propane systems. It counts the time for repay investment according to starting and using expenses. That utility answers for estimate expenses and possible savings during change of propane, crude, natural gas or electrical baseboard heaters to air source heat pump, geothermal system or natural gas.

Compare Geothermal and Propane Costs
Geothermal technology spares money daily. It exploits the stable temperature below ground so must not exert for warm either cool the house. Like this it operates more effectively and can give until 80 % fewer expenses than old system.
Home heating and cooling even costs less than cup of coffee in coffeehouse. Annual expense for warming and cooling can reach only 365 dollars. In addition, waterless DX-geothermal unit delivers free warm water for additional savings.
Because different systems use various fuels matters to know how many BTUs stores unit of fuel. For instance one gallon of propane have around 91 500 until 94 000 BTUs. For find equivalent propane price multiply the price of natural gas each therm by means of 0,92.
For estimate propane consumption in pounds use the BTU rating for ovens. If RV propane tank bears 14 gallons of LP gas when fully multiply 14 by means of 91 502. Later divide that amount by means of the whole BTU demand of used LP devices.
20 000 BTU furnace that operates permanently would exhaust 20-pound tank of propane in around 22 hours although boilers normally turnon and turn.
Efficiency one measures by means of Coefficient of Performance (COP). Electrical baseboard heaters has COP of 1. In Northeast United States geothermal heat pumps reaches COP 3,4 or more according to design of the system.
Many factors affect energy costs but annual savings estimates by means of choices in the calculator. Geothermal and air sourced heat pumps use electricity for extract free heat energy from aquifer or from air.
