Radiant Heat Systems in Boulder
Hydronic radiant heat systems use PEX tubing embedded in floors to deliver even warmth without forced-air noise or allergens. In Boulder's high-altitude climate (5,430 ft) with freeze-thaw cycles October through April, these systems suit Victorian retrofits, net-zero builds, and contemporary mountain residences seeking zone-by-zone control and lower energy bills.
Heat-loss analysis determines proper tubing loop spacing (typically 12 inches) and manifold sizing before installation. Condensing boilers achieve 95% AFUE efficiency, while zone valves allow room-by-room temperature control. Pressure testing and thermal imaging verify system integrity before drywall.
Electric radiant systems cost more to operate than hydronic systems but install faster in small areas like bathrooms. Hydronic systems require annual flushing and control checks but deliver consistent warmth with minimal maintenance. Response time is slower than forced air, so systems run continuously at lower temperatures rather than cycling on and off.
