Due to cost considerations, traditional heating will remain unaffected for now. But the new technique already found specific applications, like conveying heat in places that do not have full-time power.
If the Swedish team manages to solve the problems of toxicity and cost inherent to the new system, one can imagine charging mobile cooking devices or some other amazing usage in a near future.
