The revolutionary TOYOTOMI Oil Miser provides all the comfort and convenience of a central heating system in one small, efficient unit at a fraction of the cost. The Oil Miser can be used as either a supplement to an existing system or as a primary heat source for additions, basements, garages, and even seasonal cottages. You’ll save a bundle year after year, thanks to the Oil Miser’s unbeatable 90% efficiency.

TOYOTOMI has been using direct-vent technology in its heating systems for over 30 Years. It has proven to be not only highly efficient, but also safe and reliable.

In addition, the Oil Miser operates on North America’s most popular oil product, #2 home heating oil, as well as #1 fuel oil and K-1 kerosene.

Convenient, Easy to Use

The Oil Miser combines the most advanced technology with the economy of kerosene heating. It features a simplified digital control panel that displays room temperature, temperature settings, time, and error codes. With its programmable thermostat, the unit can remain in operation for up to 24 hours in a reliable, fuel-saving mode.

Efficient and Economical

The Oil Miser is one of the most fuel-efficient heating systems in the world today. Its special stainless steel heat exchanger carries the highest efficiency code and an 90.0% efficiency rating. You get more heat for the money than with any other heating system. The cost to operate a TOYOTOMI oil heating system is so economical that many owners enjoy annual savings of up to 70% over electric heating, 60% over propane heating, and 40% over traditional oil and natural gas heating systems.
The Oil Miser pays for itself in fuel savings in just a few short years.

Clean and Safe

A permanent mesh filter protects the circulation fan and the inside components from dust. The unit features a cool-to-the-touch cabinet. Most noteworthy is the Laser’s “pipe-within-a-pipe” forced flue venting system, a unique advance in heating. The outside pipe of the venting system brings in outside air for combustion while the inner pipe exhausts all combustion by-products to the outside. The heat is distributed by a circulation fan. The result is smokeless, odorless and clean heating. The unit also features an electric surge protector and shut-off safety system.


The Oil Miser’s large circulation fan distributes clean heat quickly and evenly. The unit automatically regulates between low, medium and high burn modes. It turns itself off when the room temperature rises approximately 4 degrees above the desired set temperature. This maintains maximum comfort while increasing efficiency and extending the life of the unit.

Easy Installation

You can easily install an Oil Miser in just an hour or two. The helpful owner’s manual provides complete, step-by-step instructions. Several installation options are available. The most common one is directly through the wall utilizing the wall venting kit. Another option is through a window opening with a window accessory kit. A full range of optional parts and accessories is available to make installation simple.
