Radiant Heat Systems
Radiant heat systems provide even, natural warmth through water-filled tubing installed in floors or ceilings. Ideal for Seattle's climate, these systems improve air quality, reduce energy costs, and offer zoned temperature control. Our team designs, installs, and repairs all hydronic systems, including custom solutions for new construction and historic homes.
Boiler Systems
We specialize in boiler installation, repair, and maintenance for residential and commercial properties. From modern high-efficiency models to rare historic systems, our mechanics address complex issues with precision. Annual maintenance and backflow testing ensure optimal performance and compliance with local utility requirements.
Domestic Hot Water
Our American-made Lochnivar Squire indirect water heaters deliver continuous hot water at lower operating costs. Designed for homes and businesses, these systems integrate with existing boilers for 2-4 times more hot water output. We offer installation, replacement, and service for residential combi-boilers and commercial Shield water heater lines.
