Laser Ignition

A patented ignition system used in Toyotomi Laser heaters, which utilizes a high-energy spark to ignite the fuel, ensuring reliable and efficient operation.

Latent Heat

The heat energy absorbed or released during a phase change of a substance, such as melting, freezing, vaporization, or condensation, without a change in temperature.

Leaky Ducts

Ductwork in heating systems that has gaps, cracks, or poor connections, leading to air leaks and energy losses, reducing system efficiency and indoor comfort.

Limit Switch

A safety device in heating systems that interrupts the flow of electricity or fuel if certain operating conditions, such as temperature or pressure, exceed preset limits, preventing damage or hazards.

Line Voltage Thermostat

A thermostat that directly controls the power supply to heating systems, typically used in electric heating systems where the voltage matches the line voltage.

Liquid Cooling System

A system that removes excess heat from electronic components or machinery by circulating a liquid coolant, dissipating heat through a heat exchanger or radiator.


Refers to the amount of heating or cooling required to maintain a desired temperature level within a space. It encompasses factors such as the size of the area to be heated or cooled, the insulation level of the building, outdoor temperature conditions, and internal heat gains from sources such as occupants, appliances, and lighting.

Load Balancing Valve

A valve used in hydronic heating systems to adjust the flow rate of water in different zones or circuits, ensuring proper distribution of heat and system performance.

Load Compensator

A control device in heating systems that adjusts heating output based on changes in outdoor temperature or building heat loss, optimizing comfort and energy efficiency.

Localized Heating

A heating method that targets specific areas or zones within a building or space, providing customized comfort and energy savings by avoiding unnecessary heating.

Log Size

The length of log that can reasonably be fitted into the stove.


A slatted or angled covering used in heating systems to control airflow or ventilation, often installed in ducts, registers, or exhaust vents to direct or restrict air movement.

Low-Emissivity (Low-E) Coating

A thin, transparent coating applied to windows or surfaces to reduce heat transfer by reflecting infrared radiation, improving energy efficiency in heating systems.

Low-Flow Radiant Heating

A type of radiant heating system that operates at lower flow rates, using less energy and reducing water consumption while providing comfortable warmth.

Low-Intensity Radiant Heater

A type of radiant heating system that emits infrared radiation at low temperatures, commonly used in outdoor or commercial applications for spot heating.


An acronym for Liquid Petroleum Gas, a flammable hydrocarbon gas liquefied through pressurization, propane.
