    Better Indoor Air Quality

    Radiant heating doesn't circulate dust or allergens.

    Efficient by Design

    No duct losses, lower thermostat settings feel comfortable, high-efficiency condensing boilers (90–96%), and effective zoning.

    How Radiant Floor Heating Works

    Radiant heating is a hydronic system that circulates warm water through PEX tubing installed in your floor. The floor becomes a large, gentle heat emitter.

    01

    Core Components

    What Makes a Radiant System Work

    Boiler

    Heats water efficiently — the heart of the system.

    PEX Tubing

    Embedded in your floor to distribute warm water evenly.

    Manifold

    Distribution hub that routes water to individual zones.

    Circulation Pumps

    Move water through the system at controlled flow rates.

    Zone Controls

    Independent room-by-room temperature control.

    Thermal Mass

    Concrete or subfloor stores and radiates heat steadily.

    Water temperatures are typically 95–120°F. Floor surface temperatures average 75–85°F — warm, not hot.

    Result: Even temperatures and stable comfort.

    Frequently Asked Questions

    PEX tubing comes with a 25-year warranty. Boilers typically last 10+ years with proper maintenance.

    It depends on access. If you have a crawlspace or basement, retrofit is often feasible. Slab foundations without access make it much more difficult. We'll evaluate your home honestly and tell you whether it makes sense.

    Tile, stone, and polished concrete are ideal. Engineered hardwood approved for radiant use works well. Laminate and LVP are generally compatible. Thick carpet with heavy padding should be avoided as it insulates against the heat.

    Yes. We can diagnose, repair, and maintain radiant systems regardless of who installed them. We also handle boiler replacements and zone rebalancing on existing systems.
