Radiant floor heating is another type of hot-water heating system.
Wright invented modern radiant floor heating, using hot water running through pipes instead of hot air through flues.
Wright was so impressed by ondol that he invented radiant floor heating which uses hot water to heat up the floor.
Each hut utilizes a contained composting toilet system, solar power, and radiant floor heating powered by a wood boiler.
The renovation included several energy-saving improvements such as the installation of solar panels and a radiant floor heating system.
Since the heating element is embedded in the floor slab, radiant floor heating is only practical for single-level houses.
Instead of ondol-hydronic radiant floor heating, modern-day houses such as high-rise apartments have a developed version of the ondol system.
Hydronic radiant floor heating systems use a boiler or district heating to heat water and a pump to circulate the hot water in plastic pipes installed in a concrete slab.
But it takes time to heat a cold room with radiant floor heating because the heating elements must warm up a large slab of concrete before the heat can rise to the room above.
The facility features environmentally friendly building practices and an energy efficient building design, such as a green roof, natural ventilating system, radiant floor heating / cooling system and daylight harvesting systems.
