    This review is about the capacity: 24 lt

    Very good expansion tank for specialized Solar system installations (such as Solar Water Heaters). It ensures stable pressure in the circuit, in my case ~2.5 bar in a 200 lt Solar system.
    However, you need to purchase a support base if you cannot make something yourself.

  • It looks good but the previous one I got from the same brand, the 24-liter one, rusted and got holes in less than two years, that's why I gave it 3 stars to see how it will go. I had bought it from another store.
    We'll see!!!!!

    This review is about the capacity: 24 lt

    While it generally seems well-made, just 3 weeks after installation and 1 week after the first little rain, it already started showing rust spots. It is supposed to have epoxy paint and certification.

    It has been about six months since I installed it in the solar panel. It has endured very cold weather and it is still functioning perfectly without losing any air
