Laser heater
From Wikipedia, the free encyclopedia
A laser heater is a type of kerosene heater.[citation needed] These heaters use an electronically guided system that burns the kerosene fuel at a high efficiency (almost 100%).[citation needed] These units produce almost no combustion exhaust gas and soot.[citation needed]
Laser heaters are popular in Japan.
These heaters are able to clean themselves and shut off when there is no oxygen left in the room for the burner to burn, making the risk of carbon monoxide poisoning very low. Temperature can be regulated very precisely.[citation needed]

[edit] Mechanics
Modern laser heaters use a button to ignite the fuel. A wick , a feature of old kerosene heaters, is not present.[citation needed]
After ignition, the temperature of the burner is raised to assure maximum efficiency of the heater.[citation needed]
Temperatures in the heating chamber can reach temperatures up to 1200 degrees celsius.[citation needed]
Efficiency of the laser heater is, therefore, highly optimised by burning any waste gases that would be otherwise released into air.[citation needed]
[edit] Safety
[edit] Fuel
A purified type of kerosene is used as a fuel, low in sulfur. Other types of kerosene are not suited for any kerosene or laser heater.
In the United States the kind of kerosene is named as: 1-K kerosene. In Belgium, this is called 'petroleum type c'.
[edit] CO and other harmful products
The safety of kerosine laser heaters is debated.
Sensitive people, for example, people suffering from asthma or heart problems, should be alert.
Portable heaters are currently considered not be a replacement for central heating.
