It runs on gasoline or diesel — whichever fuel your vehicle already carries — tapping your existing tank or a separate jerry can. Operating range is -40°F to 75°F ambient. No inverter, no shore power: 12V DC in, heat out.\u003c\/p\u003e\n\u003cp\u003eThe unit includes a built-in CO sensor and flammable gas sensor that shut the heater down automatically if dangerous accumulation is detected. A barometric pressure sensor adjusts the air-fuel ratio for altitude — tested above 11,000 ft in Colorado. Bluetooth thermostat control works up to 100 ft from the unit. Japanese glow plug is rated for 3× the lifespan of generic plugs. Controller is weather-sealed. Two-year limited warranty.\u003c\/p\u003e\n\u003caside class=\"boondock-bill\" style=\"position:relative;overflow:hidden;background:#161719 radial-gradient(ellipse 60% 80% at 82% 28%, rgba(199,93,42,0.22) 0%, transparent 60%);border:1px solid #2D2E31;border-radius:12px;padding:24px 28px;margin:24px 0;\"\u003e\n  \u003ch3 style=\"margin:0 0 14px 0;color:#E37545;font-family:Geist,-apple-system,system-ui,sans-serif;font-size:18px;font-weight:700;letter-spacing:-0.01em;\"\u003eBoondock Bill's Take\u003c\/h3\u003e\n  \u003cdiv style=\"display:flex;gap:18px;align-items:flex-start;\"\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0576\/0404\/6931\/files\/xgrid-boondock-bill.png?v=1779057958\" alt=\"Boondock Bill\" style=\"width:88px;height:88px;border-radius:50%;flex-shrink:0;border:2px solid #C75D2A;background:#0E0F11;object-fit:cover;\"\u003e\n    \u003cp style=\"margin:0;flex:1;min-width:0;color:rgba(245,247,250,0.85);font-family:Geist,-apple-system,system-ui,sans-serif;font-style:italic;font-size:15px;line-height:1.6;\"\u003eOther fuel heaters handle altitude by guessing — this one measures it. The barometer reads the actual air pressure and trims the fuel mix so it burns clean at 11,000 ft without you touching a setting. Bill's seen cheaper heaters smoke and carbon-foul themselves at elevation; the Velit doesn't. Add the CO sensor shutoff and the Japanese glow plug and you've got a heater you can run unattended overnight without losing sleep about it.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/aside\u003e","brand":"velitcamping","offers":[{"title":"Gasoline","offer_id":44559379300435,"sku":"GAS400012V","price":729.0,"currency_code":"USD","in_stock":true},{"title":"Diesel","offer_id":44559379333203,"sku":"DI400012V","price":729.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0576\/0404\/6931\/files\/velit_heater.jpg?v=1777769675","url":"https:\/\/www.xgridoutfitters.com\/ga\/products\/velit-gasoline-diesel-air-heater-14000btu-4000w","provider":"XGRiD Campers","version":"1.0","type":"link"}
