Toyotomi Laser 533/534 Direct Vented Oil Miser Heater w/ WIFI

The Toyotomi Laser 533/534 Direct Vent Heating System represents the next evolution in clean, efficient home heating. Serving as the updated, modern replacement for the legendary Toyotomi Oil Miser OM23 and Laser 530/531/532 models, the Laser 533/534 pairs a sleek contemporary design with the proven direct-vent engineering that Toyotomi has perfected over four decades. Designed to deliver the targeted warmth and ambient comfort of a full central heating system at a fraction of the operational cost and physical footprint, this unit is an economical heating solution for primary residences, basements, workshops, detached garages, vacation cabins, and mobile or manufactured homes.

Engineered for maximum fuel flexibility and eco-friendly performance, the Laser 533/534 operates efficiently on K-1 Kerosene, No. 1 Low Sulfur Fuel Oil, Ultra Low Sulfur Heating Oil, or Ultra Low Sulfur Diesel. By utilizing Toyotomi’s advanced burner technology, the system burns fuel with exceptional efficiency—allowing homeowners to consume up to 50% less fuel compared to traditional heating systems while heating the exact same space. Installation is fast and non-invasive: the sealed direct-vent system requires no chimney, complex plumbing, ductwork, or major masonry work. The flexible wall flue pipe adjusts seamlessly to fit varying wall thicknesses, requiring only a small 2-3/4" opening through an exterior wall for a discreet vent cap.

Operating with intelligent climate management, the Laser 533/534 modulates automatically between four burner power modes (including off) to precisely maintain your desired room temperature across an 8,010 to 22,000 BTU range. Modern convenience is built directly into the system, featuring full Wi-Fi compatibility for remote control, an automatic ignitor self-cleaning cycle, power failure recovery, and a customizable 7-day programmable timer with up to 30 unique On/Off intervals. Built with safety as a top priority, the unit includes an automatic emergency shut-off system, digital diagnostics, and a cool-to-the-touch cabinet that protects children and pets.
