Heat pump floor-heating units extract ambient heat from air, water, or ground, compress it, and release warmth through subfloor exchangers. Achieving COPs of 3–4, they slash campus heating energy and CO₂ by over 30%. Equipped with smart scheduling, they operate reliably down to –25 °C and deliver uniform 35–45 °C warmth. Widely adopted in retrofits, they offer safe, efficient campus heating.
