About HearthIQ
Helping homeowners make smarter energy decisions.
🎯 Our Mission
HearthIQ was created to solve a simple problem: understanding home energy savings is confusing. Whether you are considering solar panels, a heat pump, or battery storage, the real costs and benefits are often buried in sales pitches and complex spreadsheets.
We built HearthIQ to give homeowners a free educational tool that provides savings estimates based on publicly available data from sources like the U.S. Energy Information Administration (EIA), the International Renewable Energy Agency (IRENA), and official government incentive programs.
✨ Why HearthIQ?
The idea for HearthIQ started when members of our team began researching solar panels and heat pumps for our own homes. We found that many online resources were either too basic (offering generic estimates that didn't account for local rates) or focused primarily on lead generation rather than education.
We wanted something different: an educational tool that puts information first, helping homeowners explore their options before making decisions about their home's energy future.
- Educational Focus: We are not an installer or seller. Our calculator provides estimates based on public data.
- Multi-Country Support: Whether you are in the USA, Germany, UK, Australia, or India, we tailor our projections to your local electricity rates and incentives.
- Transparent Sources: We cite where our data comes from and explain how we calculate estimates.
- Free to Use: No signup required. No fees.

📚 Our Data Sources
We believe in transparency. HearthIQ calculations are based on data from trusted public sources:
- U.S. Energy Information Administration (EIA) – Electricity rates across US states
- International Renewable Energy Agency (IRENA) – Global solar installation costs
- European Energy Regulators (ACER) – EU electricity pricing data
- Government Websites – Official incentive programs (IRS, BAFA, SEAI, etc.)
We update our data regularly, but always recommend verifying current rates and incentives with official sources before making major purchase decisions.
