Pressure Vessel for Domestic Waterworks Ausdehnunggsgefäss 24 liters

I bought the boiler with membrane in May 2012. The reconstruction and commissioning proceeded without problems. However, after only 9 months the membrane had burst. On request to the seller was told that this is a wearing part and is therefore outside the statutory warranty. Thank you for cheap junk from China, for that matter membrane. The boiler is well worth the money in any case. Just as a tip for all who purchase the boiler: Buy a 20 euro membrane to the original building from the boiler and the expensive and tranquility. I forgive only one point, because it costs time and nerves and money to get a good membrane and install.

Now the boiler is a good two years old and it leaks. Specifically breaks the connection flange on the boiler, the result, pressure drop and when it comes stupid even water damage caused. On a two-time request to the seller for the purpose of goodwill or entgegegn get when buying new ones, came no reply to date. Since this is absolutely poor workmanship goes as far as the flange and also a response from the seller comes (for 3 weeks) I can not assign a point here. However, who is looking for a anderern boiler must realize that all in looking closely look identical.
By the way, my house waterworks of TIP is to be more than ten years in the open air (covered) and it has never changed anything.
