In this regard, Ho Yong Ho, one of developers, told KCNA:

The heat pipes are of great importance in producing energy-saving equipment as their electricity and coal consumption were reduced to one third and half against existing ones separately.

The Solar Heater Company introduced superconductive heat pipe in producing solar water heater, thus raising its thermal efficiency.

The pipes enjoy popularity among users for their low costs and high utility.

The pipes are produced by the International Civic Economy Cooperation Centre.
