Heating Cost Equation:
From: | To: |
The Efficiency Maine Heating Cost Calculator helps homeowners estimate their annual heating expenses based on their home's heat load, heating system efficiency, and current fuel costs. This tool is particularly useful for comparing different heating systems or fuels.
The calculator uses the following equation:
Where:
Explanation: The equation accounts for how much useful heat you get from your fuel after accounting for system inefficiencies, then multiplies by the cost of that fuel.
Details: Understanding your heating costs helps with budgeting, comparing different heating systems, and evaluating potential energy efficiency upgrades. Maine's cold winters make heating a significant household expense.
Tips:
Q1: How do I find my home's heat load?
A: A professional energy audit can provide the most accurate number. Alternatively, you can estimate from past fuel bills if you know your old system's efficiency.
Q2: What's a typical efficiency for different systems?
A: Standard furnaces: 0.80-0.89, High-efficiency furnaces: 0.90-0.98, Heat pumps: 2.0-3.0 COP (equivalent to 200-300% efficiency).
Q3: Where can I find current fuel costs?
A: Check with local fuel providers or the U.S. Energy Information Administration for regional averages.
Q4: Does this account for temperature variations?
A: No, this is a simplified calculation. Actual costs may vary with weather conditions.
Q5: Can I compare different fuels with this?
A: Yes, as long as you have the correct efficiency and cost per MMBTU for each fuel type.
