When temperatures plummet to -20°C, heating systems become both a lifeline and a liability. Did you know that PTC (Positive Temperature Coefficient) heaters can consume 30% less power than traditional resistive heating elements in extreme cold? This revelation forces us to ask: How do we balance thermal comfort with energy efficiency in subzero environments?
As global energy demand surges by 25% since 2015, water heating optimization remains the Achilles' heel of residential energy systems. Did you know that in U.S. homes, water heating accounts for 18% of total energy consumption – second only to space heating? Yet industry reports show 68% of systems operate below 50% energy efficiency. What's holding back progress in this critical sector?
