it exchanges with 24°C earth, not the weather — and your generator becomes optional.

Who it's for

Built for the big house.

1-kanal villa at dusk — The 1-kanal home. Eight ACs, a roaring generator, a June bill you don't show guests. One system retires all of it.

Drilling at a home under construction — Building or renovating. Grey structure is the perfect moment — loops and ducts go in clean. We work with your architect.

Family at home in a cool lounge — Overseas owners. Building for family from Dubai or London? Everything runs on WhatsApp — and we maintain it for life.

How it works

The earth is 24°C. We plug you in.

Drilling rig on a villa driveway — 1 · We drill. Two loops into ground that stays 24°C all year.

Terra unit in its rooftop mechanical room — 2 · We connect. One roof unit moves heat out in summer, in during winter.

Cool marble living room — 3 · The sun runs it. The solar roof powers the system. Your bill stays at zero.

One system, end to end

Everything included. Installed by us.

The Terra unit

One sealed machine — cools and heats. White or graphite.

Geothermal loops

Boreholes into the 24°C earth. We drill them.

Indoor units

Wall units in white, graphite or champagne — or hidden ducts

Mechanical room

Fully enclosed on your roof; its solar roof powers the system

Smart control

Wall thermostat + Kelvin app — every room, solar, battery and loop, live

Night battery

Optional: the sun charges it, it runs the night

Inside the machine

How the heat pump moves heat.

The core is a Panasonic-EVI / Copeland-scroll ground-source inverter built by SPRSUN — the same plant that supplies the majors, to our spec. Watch its refrigeration cycle, and flip it from cooling to heating.

Cooling: the compressor drives refrigerant to dump your rooms' heat into the 24°C ground loop. Red = hot, blue = cold. Drag to orbit.

Living with it

Quiet. Invisible.

Bedroom at night with a slim wall unit above the bed — Bedrooms stay at setpoint all night — 32 dB, quieter than a ceiling fan

Family lounge cooled by a concealed ducted unit — Ducted option: nothing on the walls, just a slim vent in the ceiling
