London: Scientists have developed a new bladeless fan heater which they say can quickly warm up an entire room without any visible moving parts.
Developed by scientists at British industrial designer James Dyson's company, the stylish "Dyson Hot" uses ceramic stones to generate heat and will cost around 270 pounds.
For its making, the scientists combined jet engine technology and the sort of thermoplastics used to make riot shields, car bumpers and crash helmets.
The Dyson Hot is a world away from the noisy traditional fan heaters which have remained largely unchanged for more than 30 years, said its developers.
"We built hundreds of prototypes to develop a heater that heats a room faster than any other. Other fan heaters rely on inefficient motors or dust friendly grills," James Dyson said.
"As the heat rises you're left with a partially heated room and a worrying burning smell. Dyson engineers have developed a heater that produces no smell and heats the whole room," he said.
The heater represents a big advance on the Dyson's hugely successful bladeless fans, which were introduced in 2009.
The design replicates the loop style of the original fans - something like a child's bubble blowing wand. But, rather than bubbles, each one magically pumps out vast quantities of warm air.    

It relies on Dyson's patented Air Multiplier technology, which massively amplifies the hot air it can create.
The net effect is that the amount of warm air generated is some six times greater than the amount drawn in at the bottom in a process known as inducement and entrainment.
The heater has its own thermostat which allows it to heat a room between 1 and 37 degrees Celsius. It will click on, should the temperature drop below the set figure.
