Hello,
we had a turnkey build according to VOB. Sections 13 paragraphs 4 and 5 are included in the construction contract.
Last week, I discovered water damage in the heating cellar caused by the heat exchanger of the heating system’s fresh water module. I have no maintenance contract for the heating system. There is also (currently) no building insurance covering water damage.
The house was handed over at the end of May 2013.
In 2014, the (developer under warranty) repaired a leaking shut-off valve of the fresh water module.
In 2017, the (developer under warranty) replaced the automatic air vent of the heating system because it was leaking.
Who is now responsible for the defect of the module and the consequential damage (water damage)?

Based on a 2018 analysis of my drinking water, two values are close to the limit for the "standard" heat exchanger. With these values, they would recommend the more expensive nickel-brazed one to avoid such corrosion. To even have a chance of recourse, the builder would have had to know about the water values and for them to be part of the contract (for example, you knew about the poor water quality and included the water utility’s report in the contract). Additionally, the water quality could have worsened in recent years. It sounds strange because under normal conditions, a heat exchanger does not develop rust issues after just 4-5 years. These components usually last much longer! Typically, there is a sacrificial anode inside that is checked and replaced if necessary during maintenance.
Something definitely doesn’t add up here. Most likely, you damaged the unit yourself somehow. In the future, have a professional company perform the maintenance. That way, at least you have someone to hold accountable, because wear parts should not cause additional damage (for example, a worn-out sacrificial anode causing the tank to rust through) if the inspection and replacement of these parts was included in the maintenance agreement (which makes sense).
