NWP500 is an eco-friendly, low-noise hot water supply device that reduces costs with 3-4 times more energy efficiency than general electric water heaters based on our brand’s unique heating technology, and reduces greenhouse gas and carbon dioxide emissions. The interior is made of stainless steel tank, so it is highly resistant to corrosion and has excellent hygiene, so you can safely receive hot water. It is also an eco-friendly product that uses 4th generation HFO foam with a low greenhouse index. It provides a home energy report through app linkage, and users can efficiently manage energy and easily control the product with reservation and error notification functions. In addition, the product design takes into account the narrow environment of underground spaces where it is mainly installed and the average height of the user, making it a user- and installer-friendly product.
