David Friedman’s Substack • 233 implied HN points • 25 Nov 24
🕹 Technology Energy Design Regulation Efficiency
  1. Heat pumps can be more cost-effective than gas furnaces, but it depends on current energy prices. It's important to understand the right settings on your thermostat to save money.
  2. Many thermostats are designed to prioritize heat pumps over gas furnaces, which can lead to unnecessary costs if gas heating is cheaper. Users should consider switching to 'emergency heat' if they have both systems.
  3. Regulations often push for efficiency in heating systems, but not all thermostats work well for every dual-fuel setup. It's essential for customers to be informed about the best options for their specific heating needs.
