Dyson has recalled every unit of its Dyson Hot fanless heater, after the risk of fire has arisen in a handful of the units sold since 2011. 

"We have sold a million heaters around the world; we have seen a small number short-circuit, which in four cases resulted in contained burning," Max Conze, CEO at Dyson, told Reuters on Monday. "Although there have been no instances of personal injury or damage to property, it's four too many. So we are working with the relevant regulatory bodies and preparing for a voluntary recall."

The Britain-based vacuum company has setup a Dyson Recall website, where customers will soon be able to return their Dyson Hot units to be fixed. Right now, the page reads: "We are actively working to resolve this issue in conjunction with the relevant regulatory agency. We will provide further instruction to our consumers within 24 hours."

The Dyson Hot is priced at £270/$250, providing customers with a warming version of its fanless Air Multiplier line. Everything can be controlled via a remote control that can be magnetically attached to the top of the fan when not in use.

Dyson says only the Dyson Hot version of the Air Multiplier line is affected. 

Dyson has a fairly good reputation when it comes to product safety. In 2010, it recalled Dyson DC05 Motorhead cleaner in the US after some users reported an electric shock risk. Other than that, complaints have been few and far between.
