Radiant Heating in San Francisco

From ADU conversions in the Sunset to historic Victorian renovations in Pacific Heights, radiant floor heating is the ideal comfort solution for San Francisco's unique building stock. No ductwork, no noise — just consistent warmth that SF's fog-belt climate demands.

Why Radiant Is Perfect for SF Homes

No Ductwork Required

Victorian flats, Edwardian homes, and Sunset bungalows were never designed for forced-air ductwork. Routing ducts through 100-year-old framing requires major structural work. Radiant heating runs through tubing in the floor with no structural compromise.

  • Ideal for ADUs and garage conversions where there's no room for ductwork
  • Works with any floor covering — tile, stone, engineered hardwood
  • No visible registers or grilles — completely invisible in the finished space
  • Quieter than any forced-air system — no blower motor noise

No structural compromises to vintage framing

Efficient in SF's Marine Climate

SF's foggy, consistently cool climate is ideal for radiant heating. The moderate, steady heating load means a well-designed system runs at its maximum efficiency point. With a condensing boiler or heat pump, you get 90-97% efficiency delivering exceptional comfort.

  • Low-temperature operation maximizes condensing boiler and heat pump efficiency
  • No heat loss through ductwork — 100% of energy reaches the conditioned space
  • Floor-level heat stays with the occupants, not the ceiling
  • Air-to-water heat pumps achieve COP of 3-5 in SF's mild climate

Exceptional comfort for cold, foggy days
