Choose aluminum profile radiators and high-pressure die-cast modular radiators. These radiators are cast as a single piece, eliminating the issue of weld leakage. Moreover, their advantage lies in being不受小区采暖系统限制，even in open boiler systems, they are immune to oxygen corrosion. Due to the modular design, if the indoor temperature is not sufficient after one heating season, one or two additional panels can be added the following year to meet your needs, without having to replace the entire heating set like with steel radiators. Additionally, since aluminum profile radiators have different water quality requirements than steel, it is advisable to avoid installing aluminum radiators in conjunction with other materials.
