With Monitor gone, customers looking for a new, direct-vent heater that burns kerosene are left with Toyotomi’s Laser heaters. Toyotomi also makes a model that burns heating oil.

Customers of Ken’s Monitor & Toyo Sales are thrilled to get through winter burning 300-400 gallons of kerosene in their superefficient units. An old-tech oil furnace could guzzle double that amount.
