Icy Fiery Dual-climate radiant systems
Anadi designs one plant for two climates: silent radiant heat indoors, and snow-melt that keeps drives, ramps, and steps clear. No salt. No drafts. No compromise.
Two climates. One plant.
Icy
Hydronic and electric melt for drives, stairs, loading docks, and hotel entries. Moisture and slab sensors wake the system only when ice would form.
Fiery
Floors, walls, and ceilings that warm people and surfaces first. Silent. Even. Heat-pump ready at 30–45°C flow.
The Anadi approach
We treat indoor heat and outdoor melt as one hydronic story. The same heat pump, the same mixing, two temperature circuits. Ice never reaches the threshold. Fire never leaves the floor.
Systems
PEX circuits in screed, staple-up, or panel systems. Designed for heat pumps, condensing boilers, and mixed-temperature plants.
Hydronic and electric melt for drives, ramps, stairs, and docks. Clears surfaces without salt damage.
Thin-profile cable and mat systems for bathrooms, kitchens, and rooms where a boiler plant is not practical.
Targeted melt for thresholds, hotel drop-offs, and garage aprons that must stay clear every freeze.
Panel and plaster-in circuits where floor depth is limited, or where cooling and heating share the same surface.
Indoor stats, weather compensation, and outdoor ice sensors on one logic. Comfort without overshoot. Melt without waste.
How it works
Indoors, warm water raises the floor a few degrees so heat radiates to people. Outdoors, the same idea keeps the slab just above freezing. Air stays still. Ice never bonds.
We calculate fabric losses inside and freeze risk outside so each loop is sized, not guessed.
Tight spacing at glazing and at slab edges. Separate mixing for fiery rooms and icy drives.
Heat-pump curves indoors. Moisture plus slab sensors outdoors. One commissioning report.
Why dual climate
No fans, no duct rumble. Bedrooms stay acoustically clean while the drive clears itself.
Melt slabs protect stone, steel, and landscaping. Ice never needs a shovel at the door.
Walls stay clear. Windows run to the floor. Entries stay dry without mats of grit.
Heat pumps run in their best range for both fiery rooms and icy slabs.
Selected work
Residence · Hillside
Fiery: 1,240 m of PEX, five manifolds, 38°C flow. Icy: heated garage apron and stone stair that never glaze.
Hospitality · Courtyard hotel
Electric mats in wet rooms. Hydronic melt at the porte-cochere.
Civic · Gallery wing
Ceiling panels at 20°C. Icy ramp for accessible entry, no salt near limestone.
Engagement
Site visit or drawing review. We confirm indoor build-up, outdoor slab, and whether hydronic, electric, or mixed is right.
Heat-loss and freeze model, two-temperature manifolds, pipe layout, and control schematic.
Crews lay indoor and melt circuits, pressure-test, and close the slab. As-builts at every manifold.
Balance fiery rooms. Set icy idle and storm. We stay through the first heating season.
The stone is simply warm, and the drive is simply clear. Ice and fire, finally in the same house.
Questions
Yes. Indoor radiant and outdoor melt share a heat pump or boiler, with separate mixing. Rooms stay at 30–45°C flow. Melt only rises when sensors call for it.
Yes, with the right assembly. We specify maximum surface temperature, underlayment, and species so engineered wood stays stable.
Idle keeps the slab near freezing so a storm does not start from ice. Storm mode raises output. We size for your climate, not a generic wattage.
Retrofits use staple-up, overlay panels, or electric mats indoors, and overlay melt outdoors where structure allows.
Both. Architects bring us in at schematic design so slab depth, insulation, and plant room are correct before tender.
