Building a custom home in Marin is your opportunity to design perfect comfort from the ground up. We partner with local architects and builders to install high-performance radiant systems that are invisible, silent, and dramatically more efficient than forced air.
Marin homes often feature large glass doors and open floor plans to embrace the outdoors. Radiant heating warms the floor mass, meaning you stay comfortable even when doors are open to the patio — unlike forced air, which just blows heat outside.
Warms the floor mass, not the air outside
Marin's mild climate makes air-to-water heat pumps exceptionally efficient. We can design systems that use electricity to heat your floors in winter and chill water for cooling in summer — perfect for warmer Novato days and fully compatible with solar.
COP of 3-5: for every 1kWh of electricity, you get 3-5kWh of heat
Marin's harder water (compared to SF) can scale up boiler heat exchangers within a few years without proper treatment. On every new construction project, we install mandatory magnetic dirt separators and chemical feeders to protect your heating system investment for decades.
Magnetic dirt separators installed standard
For modern slab-on-grade homes common in Lucas Valley and new developments, we tie PEX tubing directly to the rebar before the concrete pour. This creates a massive thermal battery that stabilizes your home's temperature day and night.
For multi-story custom homes in Mill Valley or Tiburon, we use structural subfloor panels with grooves for the tubing. These offer faster response times than concrete — ideal for zones that need to heat up quickly in the morning.
We ensure your heating design meets California's strict energy code requirements, selecting the right high-efficiency boilers or heat pumps for your specific climate zone in Marin.
We design for Marin's microclimates. A home in foggy Sausalito needs a different heat load calculation than a sunny estate in Novato. Every system is designed for the actual conditions of your site.
We aren't driving in from the city. We are local to Novato, meaning faster response times for site visits and smooth coordination with your architect and builder throughout each phase of construction.
We specialize exclusively in water-based heating systems. We don't do forced air. This focus means we deliver a deeper level of expertise than general HVAC contractors who dabble in radiant.
We know the local building departments and inspectors. We handle all Title 24 compliance for the mechanical system, keeping your project on schedule and your GC happy.
