Solaraven
8419120000
The tankless solar water heater from Solaraven (Model: RNE-TS-50) is a revolutionary solution designed to meet the demands of modern high-rise buildings and customized whole-house designs. Unlike traditional solar water heaters that rely on bulky separate tanks, this innovative system integrates heat storage and absorption into a single unit—its 137mm diameter solar vacuum tubes not only collect solar energy but also serve as built-in heat storage devices. By eliminating the need for an external or indoor water tank, it solves the aesthetic and space issues that make many real estate developers reject conventional models. This building-integrated design aligns perfectly with architectural quality and style, while enhancing green building ratings, making it a top choice for both residential and commercial projects.

Equipped with Φ137mm solar vacuum tubes, the system offers higher heating efficiency compared to flat panel collectors. Each tube houses a pressurized food-grade 304 stainless steel inner tank, ensuring dual functionality of heat collection and storage.
The integrated 304 stainless steel cylinder inside each vacuum tube eliminates leakage risks, while the pressurized design enhances stability and anti-freeze capabilities, suitable for various climate conditions.
Designed for seamless embedding into buildings, the tankless structure avoids the "boil-like" external tanks or "tumor-like" indoor tanks of traditional models, preserving architectural beauty.
Supports vertical or horizontal installation on the ground, rooftop, terrace, or wall, adapting to diverse spatial constraints of high-rises, villas, and commercial buildings.
The integrated heat storage and absorption design enables rapid heating, providing instant hot water without waiting, meeting the needs of whole-house hot water usage.
