Ground-Source Heat Pump Installation in Pioneer Square

Common Challenges

• Reclaimed tideflats cause ground loop settlement

  Soft marine clays beneath Pioneer Square shift under weight, causing loops to settle and lose contact with surrounding soil, reducing heat transfer by 20-30%

• Historic brick buildings lack space for horizontal loops

  Restored warehouses and lofts have limited yard access, requiring vertical drilling through marine clays to reach stable bedrock 80-120 feet down

• Downtown flood risk increases heating demand

  Pioneer Square's low elevation and marine exposure mean higher humidity and heating loads, requiring properly sized systems to maintain comfort year-round

How We Help

• Vertical loops drilled 80-120 feet to bedrock

  Drilling through soft marine clays to stable bedrock ensures loops stay in place and maintain consistent heat transfer for 50+ years

• 40-60% lower heating bills year-round

  Ground-source systems cut energy costs by 40-60% compared to electric resistance or gas furnaces, with payback in 7-10 years

• 30% federal tax credit plus Seattle rebates

  Federal tax credits cover 30% of installation costs, and Seattle City Light rebates add $500-$1,500 per ton of capacity

• Systems sized for historic building heating loads

  IGSHPA-certified professionals calculate heating and cooling loads for brick buildings with high ceilings and large windows, avoiding undersized systems

• Clear quotes covering ground loop depth and permits

  Upfront pricing includes soil testing, vertical drilling, indoor unit, ductwork integration, and Seattle permit coordination before work begins
