How Efficiency Maine’s Online Calculator Tools Can Help Save You Money

Efficiency Maine’s website offers a range of tools that can help you assess the potential benefits and simplify the process of upgrading your home with energy-efficient technology. In this blog post, we’ll highlight three of these tools and describe how you can use them to kickstart your home energy efficiency project.

Compare Home Heating Costs Calculator

This tool helps you estimate what your annual heating costs would be using different heating systems. Compare your current system’s costs to options like heat pumps to see potential savings.

Here’s how you can use this tool:

1. Find the row that best describes your home’s heating system configuration.
2. Update fuel cost and other relevant assumptions if they differ from the default values (efficiency rating is under “show details”).
3. Click “Calculate.”
4. Press Increase/Decrease until Annual Cost on the row that represents your current system matches yours.

Compare Your Home’s Overall Energy Efficiency Calculator

This tool helps you assess your home’s overall energy efficiency compared to that of a typical weatherized Maine home.

Here’s how you can use it:

1. Enter your home’s square footage.
2. Enter your home’s annual fuel usage. You can enter amounts in more than one type of fuel if your home has multiple heating sources.
3. Click “Calculate.”

If the calculator shows that your home uses more energy than a typical weatherized home, you might want to consider using Efficiency Maine’s vendor locator tool to help you find a contractor who can help you assess ways you can maximize your savings with a more energy-efficient heating and cooling solution.

Compare Water Heating Costs Calculator

This tool shows the approximate costs of heating water for a typical family using various common water-heating technologies. It can help you compare your current system’s costs to options like a heat pump water heater.

Gallons-per-day, temperature rise, cost-per-unit, and energy factor values are all adjustable in this calculator. To use a different fuel costs and/or energy factor, type the new values into the fields and then click “Calculate.”

Efficiency Maine’s online calculator tools are a great starting point for your home energy efficiency upgrade projects. You can use these tools to estimate potential savings from upgrades like heat pumps, heat pump water heaters, and proper insulation. Get started by locating a Residential Registered Vendor near you.
