{"product_id":"rex-nordic-ah-810i-infrared-heater","title":"Rex Nordic AH-810I Infrared Heater","description":"\u003cp style=\"text-align: center;\"\u003eThe Rex Nordic AH-810i delivers 75,000 BTU\/h (22 kW) of silent infrared heat for spaces up to 70,600 ft³ (2,000 m³) — warehouses, industrial halls and large job-site interiors. No exhaust pipe, no diesel smell, no installation: plug into a standard outlet (~80 W draw, 120 V\/60 Hz), fill the 18.5 gal (70 L) tank with pump diesel, set the thermostat, and get back to work.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eInfrared warms people, floors and equipment directly instead of blowing hot air to the ceiling — so comfort arrives at working height and recovers fast after a door opens. The patented triple-combustion burner with ceramic-coated heat exchanger is why there's no flue and no smell, and internal sound damping keeps the unit at 48 dB: conversation-level, all shift long.\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eSmart controls come standard: WiFi (optional 4G) with the Rex Nordic App for remote start and temperature control, a soft-touch LED panel, thermostat from 32–104 °F (0–40 °C), a 24-hour stop timer and interval cycling. Automatic restart resumes your settings after a power cut. At full output the burner uses 0.50–0.58 gal\/h (1.9–2.2 L\/h) — one tank runs 32–37 hours flat-out, and far longer under thermostat control.\u003c\/p\u003e\n\u003ch1 style=\"text-align: center;\"\u003eFeatures\u003c\/h1\u003e\n\u003cdiv class=\"metafield-rich_text_field\" style=\"text-align: center;\"\u003e\n\u003cp\u003e75,000 BTU\/h (22 kW) for spaces up to 70,600 ft³ (2,000 m³)\u003c\/p\u003e\n\u003cp\u003eWiFi connectivity with the Rex Nordic App (Android\/iOS), optional 4G\u003c\/p\u003e\n\u003cp\u003eRuns on standard #2 pump diesel or renewable diesel (HVO\/R99)\u003c\/p\u003e\n\u003cp\u003eExtra-large 18.5 gal (70 L) fuel tank — 32–37 hours per fill at full output\u003c\/p\u003e\n\u003cp\u003eFuel use 0.50–0.58 gal\/h (1.9–2.2 L\/h); thermostat cycling cuts real-world consumption\u003c\/p\u003e\n\u003cp\u003eAutomatic thermostat, 32–104 °F (0–40 °C)\u003c\/p\u003e\n\u003cp\u003e24-hour stop timer and 5–60 minute interval timer\u003c\/p\u003e\n\u003cp\u003eAutomatic restart resumes your settings after a power cut\u003c\/p\u003e\n\u003cp\u003eComprehensive safety systems: tilt detection, overheating protection, automatic shutdown\u003c\/p\u003e\n\u003cp\u003eSoft-touch LED control panel\u003c\/p\u003e\n\u003cp\u003eUltra-quiet 48 dB operation\u003c\/p\u003e\n\u003cp\u003eHeavy-duty industrial build: 51 × 14 × 53 in (130 × 35 × 134 cm), 179 lb (81 kg)\u003c\/p\u003e\n\u003cp\u003eMinimal ~80 W draw from a standard 120 V\/60 Hz outlet\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 style=\"text-align: center;\"\u003e\u003cstrong\u003eUse cases:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv class=\"metafield-rich_text_field\"\u003e\n\u003cp style=\"text-align: center;\"\u003eWarehouse bays\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eManufacturing halls\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eDistribution centers\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eEquipment storage\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eEvent build-outs\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eLarge enclosed job sites\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eAgricultural facilities\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003eCuring and thaw work\u003c\/p\u003e\n\u003ch1 style=\"text-align: center;\"\u003eSpecs\u003c\/h1\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0659\/6801\/3466\/files\/Rex_Nordic_Specs.png?v=1793989991\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch1 style=\"text-align: center;\"\u003eDownloads\u003c\/h1\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003ca href=\"https:\/\/rexnordic.com\/cdn\/shop\/files\/REX_brochure_2026_US.pdf?v=7478540797007403985\" target=\"_blank\"\u003eBrochure\u003c\/a\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003ca href=\"https:\/\/rexnordic.com\/cdn\/shop\/files\/US-REX-AH210-AH310-AH810-user-manual-2025.pdf?v=11828945033190831962\" rel=\"noopener\" target=\"_blank\"\u003eUser Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Rex Nordic Heaters","offers":[{"title":"Default Title","offer_id":68076243288218,"sku":"AH810i","price":4490.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0659\/6801\/3466\/files\/81oi.png?v=1793990125","url":"https:\/\/flatironsfire.com\/products\/rex-nordic-ah-810i-infrared-heater","provider":"Flatirons Fire","version":"1.0","type":"link"}
