Experience the ultimate in home comfort. We design and install efficient radiant heating systems for new construction, remodels, and Eichler homes throughout San Francisco and Marin County.
Radiant systems circulate warm water through tubing in your floors, turning the entire surface into a quiet, even, and efficient heat source.
Unlike forced air that blows dust and hot air through vents, radiant heating warms your home from the ground up. This method heats objects in the room, providing a more consistent and comfortable warmth.
Each room or "zone" has its own thermostat, allowing you to control the temperature precisely where you need it.
We offer a range of installation methods to suit any project, from new construction to historic retrofits.
For new construction or ADUs, we embed tubing directly into the concrete slab before it's poured. The concrete slab becomes a thermal mass that radiates heat evenly.
Highly efficient and ideal for new builds.
If we can access the floor from below (e.g., above a garage), we can staple tubing directly to the underside of the subfloor. Heat conducts up through your existing flooring.
Perfect for retrofits where floors are already in place.
For maximum efficiency, we install aluminum heat transfer plates beneath the subfloor. These plates distribute heat more evenly and improve system responsiveness.
Costs more but performs better. Best for areas with high heating demands.
We use a low-profile interlocking panel system that installs on top of your subfloor. The tubing snaps into the panels, and your finished floor goes over it.
Great for remodels where accessing the floor from below isn't an option.
Modern panel radiators mount on your wall and circulate hot water. This is an excellent retrofit option as it doesn't require opening up floors or ceilings.
Clean, modern look. No demolition required.
While there's a solution for almost any home, installation is most cost-effective during new construction or major remodels when floors and walls are open.
We work with architects and general contractors from the design phase. We do a takeoff from the plans, figure out the most efficient option versus the most cost-efficient option, and design a system that works with your budget.
Adding radiant heating during a remodel is perfect because everything's already open. Especially popular for ADUs, garage conversions, and additions.
We service and repair all radiant heating systems - including those original Eichler systems from the 50s and 60s.
Radiant systems require a boiler to heat the water. We design and install the complete system, ensuring the boiler is perfectly matched to your home's needs.
A "combi" boiler handles both radiant heating and domestic hot water in one compact unit, saving space and cost.
Best for: ADUs, smaller homes, space-conscious installations
For larger homes or those with high heating demands, a dedicated system boiler provides more capacity for multiple zones.
Best for: Large homes, multiple zones, high-demand applications
The right boiler is critical. We perform precise load calculations based on your home's size, insulation, and window area to ensure your boiler is sized for efficiency, not just square footage.
Eichler homes in Lucas Valley and throughout Marin were some of the first homes in America to have underfloor heating. They were designed in the 50s and 60s with boiler systems on a pier and post foundation that allowed for open floor plans.
These systems are now 60+ years old. Many are failing or have already failed.
New high-efficiency boilers are precision machines. Connecting them to a dirty system is a recipe for failure. We ensure your vintage piping is clean and sound before upgrading your equipment.
This is our specialty. Over 20 years installing radiant heating throughout the Bay Area. We know what works and what doesn't.
We collaborate with your architect, designer, and general contractor to make it seamless. We're easy to work with and flexible on timing.
We'll give you the most efficient option and the most cost-efficient option. You decide what works for your budget.
From Victorian flats in SF to Eichler homes in Marin, we understand the unique characteristics of Bay Area construction.
It depends on the type of installation, square footage, and whether it's new construction or retrofit. We provide detailed estimates that break down all costs. Call us for a free consultation specific to your project.
Yes. If you have access to the underside of your floor (like above a garage), we can install it without tearing up your floors. Wall radiators are another retrofit option that requires minimal demo. During a remodel when things are open, it's even easier.
The piping in your floor can last 50+ years (Eichler systems prove this). The boiler typically lasts 15-20 years with proper maintenance. Pumps and controls are easily serviceable.
No, it's typically more efficient than forced air. Radiant systems operate at lower temperatures and don't lose heat through ductwork. You're also heating the mass of the room, which maintains temperature longer.
Radiant heating is for heat only. If you want AC, you'll need a separate system (like ductless mini-splits). Many Bay Area homes don't need AC, which is why radiant heating is so popular here.
For new construction, we coordinate with your builder's schedule. For retrofits, it depends on the scope - a simple staple-up installation might take a few days, while a full-house remodel integration takes longer. We'll provide a clear timeline during the estimate.
Modern PEX piping is extremely reliable and rarely leaks. If there is a leak, we can pressure test to locate it and make repairs. For older systems like Eichlers, we pressure test before installing new boilers to catch any issues early.
Absolutely. That's one of the best features of radiant heating. Each zone has its own thermostat, so you can have your bedroom at 68 and your bathroom at 72. We design the zones based on how you use your home.
Whether you are building new, remodeling, or need service for an Eichler home, we have the expertise to do it right.
