eco-friendly “flint bioheater” uses cooking oil as fuel to release heat

Cooking oil inside the flint bioheater

Unichest’s Flint Bioheater warms rooms and spaces using and recycling cooking oil as fuel, reducing carbon emissions and bass climate change repercussions as believed by the product company. The design looks like a watch camera or one home technology industrial size device. The wheelbarrow style allows its users to lug the bioheater to different places without the need to drag it. The interior of the Flint Bioheater (see image below) incorporates steel as the primary material, and color variations are also available including black, silver, and orange.

flint bioheater for leftover oil

Korean energy company Flint is adopting combustion technology that incinerates natural oil-based fuel without chemicals, including – but not limited to – cooking, animal fats, plants, microalgae, coffee and l insect oil. The company believes that cleaner, more economical energy is available almost everywhere, and its technologies aim to enable users to use their leftover petroleum as fuels, produced at low cost without additional processing.

Eco-friendly ‘Flint Bioheater’ uses cooking oil as fuel to release heat

Flint bioheater designed by Unichest

To realize its vision, the company called on a design studio Unichest to develop the style and prototype of a heater that would allow the use of cooking oil as the primary engine that would run the heater. The Unichest team – consisting of Cho Sunghwan, Lee Sooyeol, Park Yeongeun, Yang Sihoon and Lee Hyunju – unveiled Flint Bioheater in 2021, a bioheater that uses cooking oil as fuel and uses a combustion module to transfer the heat. The team created a design based on an easy-to-use composition and manufacturing method that uses detail and shows a clean, minimal appearance that goes well with the cluttered farmhouse atmosphere.

From animal and vegetable oil to biodiesel

Flint says that while animal and vegetable oils can be considered environmentally friendly and have a high rate of continuous production, this type of oil has a high flash point and viscosity that makes them difficult to ignite. The company’s approach is to convert this type of oil into biodiesel through a chemical process, but burning them directly without refining chemical procedures. The company believes that by continuing this process and installing this feature in its products, it will hardly emit harmful carbon, thus keeping the atmosphere clean and renewable.

Domestic and outdoor air pollution

The flint bioheater is a substitute for the use of fossil fuels and biomass which seriously harm the environment and is an alternative to coal heating. The company claims that in winter, homes in Asian cities use coal stoves which contribute to worsening air pollution. Based on research 2016 by the University of British Columbia, more than 5.5 million people die prematurely each year from indoor and outdoor air pollution, and more than half of the deaths occur in China and India.

Flint – he aims to add more in the future – has developed his own combustion engine that burns contaminants in exhaust gases with high temperature and clean burning. “It is possible to significantly reduce the amount of soot generated by incomplete combustion and reduce heating costs with high thermal efficiency”, said Flint.
