Why Toyotomi?

Toyotomi makes a wide range of oil-burning heaters, stoves, and on-demand water/heating systems designed to deliver reliable warmth and hot water with high efficiency, especially in places without easy access to utility power or natural gas.

Built for Efficiency & Practical Performance

  • Many Toyotomi water heaters operate in on-demand or semi-on-demand mode. That means they don’t keep a large tank of hot water ready 24/7, which avoids energy losses from stored water cooling down. The OM-122DW semi-on-demand model is rated about 88% efficient.

  • The OM-128HH hydronic heater is compact and low-mass but still delivers strong performance. It has roughly 87–90% combustion efficiency, depending on installation.

  • Toyotomi vented heaters (like the L-301/302, L-531/532, L-60AT, L-731/732) offer a range of heating sizes, so you can match the heater to the space: small cabins, rooms, or larger off-grid homes. Their direct-vent design helps maintain indoor air quality and efficiency.

What Models & Sizes Are Available

  • Vented and direct-vent heaters: small to large models (about 15,000 BTU to over 40,000 BTU) to heat a single room or an entire off-grid house depending on insulation, climate, and layout.

  • Water and hydronic heaters: models like the OM-122DW and OM-128HH provide high output with on-demand heating, using fuel only when hot water is needed and reducing waste.

Why Toyotomi?

  • High reliability and durability, critical where servicing is difficult or delayed

  • Significant fuel savings compared to older or less efficient systems

  • Compact designs that make installation easier in remote or tight spaces

  • Options for direct-vent or chimney venting to suit different building types

With Toyotomi stoves, heaters, and water heaters, you gain efficient heating and hot water solutions that are proven in Alaska’s most demanding environments.
