Free 24/7 Solar Heat. Even at -40°C (-40°F).

The world's first containerized unglazed heating wall — mobile, off-grid heat for farms, construction, and remote sites.

What It Is

A 40ft shipping container with a perforated solar absorber on one side. Sun heats the metal. Air passes through tiny holes. Hot air flows into your building. A gravel battery inside stores heat for nighttime — delivering free heat 24 hours a day.

No diesel. No gas. No emissions. No noise.

Why It Works

• No glass, no snow problems — Snow slides off the vertical wall. No ice, no downtime.
• Works in extreme cold — Delivers heat even at -40°C (-40°F).
• 24/7 operation — The gravel battery stores 100+ kWh for nighttime heat.
• Plug-and-play — Drop it, connect the duct, turn it on. Under an hour.
• Zero fuel costs — Runs on sunlight and a small 12V fan powered by a roof solar panel.
