We have now used this boiler exactly 4 weeks and it is not just down to strong rust, but also the screws of the 'holder' are completely rusted. Despite the care to the manufacturer's instructions. Furthermore, the said bracket has front completely solved. This is not only annoying, but also extremely dangerous. The boiler can now fulfill no function after a Montat. The lid, which generates the sound, namely, connected to the holder. I am not alone, terribly disappointed because of the price.
