Toyostove by Toyotomi Laser 733/734 Direct Vented Heater w/ WIFI

The Toyotomi Laser 733/734 Direct Vent Heating System delivers high-capacity, energy-efficient heating designed to replace the classic Toyostove Laser 73, 730, 731, and 732 models. Featuring a refreshed, contemporary design alongside Toyotomi's proven combustion engineering, the Laser 733/734 provides the warmth and comfort of a central heating system at a fraction of the operating cost and space. It serves as a reliable heat source for primary living areas, basements, workshops, hunting cabins, and certified mobile or manufactured homes.

Built for maximum performance and fuel flexibility, the Laser 733/734 operates cleanly on K-1 Kerosene, No. 1 Low Sulfur Fuel Oil, Ultra Low Sulfur Heating Oil, or Ultra Low Sulfur Diesel. Toyotomi’s direct-vent technology allows homeowners to use up to 50% less fuel to heat the same area compared to conventional heating systems. Installation is fast and non-invasive, requiring no chimney, ductwork, plumbing, or special electrical wiring. The flexible wall flue pipe adjusts to varying wall thicknesses, requiring only a single 2-3/4" opening through an exterior wall for a low-profile vent cap.

Engineered for large spaces, the Laser 733/734 modulates across four burner modes (including off) to output between 15,000 and 40,000 BTUs. Modern convenience features include full Wi-Fi compatibility, a 7-day programmable weekly timer supporting up to 30 On/Off intervals, power failure recovery, and an automatic ignitor self-cleaning cycle. Built-in safety features include an emergency automatic shut-off system, digital diagnostic codes, and cool-to-the-touch cabinet panels.
