1. The aluminum heater is with steel tubes, which is processed by acid for against rusty, oxidant.
2. The advantages of steel pipes used of heater, and heating systems. Acid steel has the same antirust, anticorrosion as aluminum and brass, it is harder than brass and aluminum materials, so it is suitable for different condition of water quality
3. This kind of electric heater is under sophisticated technological requirements, and only industrialized production of the high-degree machinery plant can achieve its high-quality requirement.
4. The perfect combination of aluminum heater and high-quality result in the heat dissipation capacity increasing more than 50%
5. Cost-effective, so it's an ideal choice for residential heating.
