Solar yield too low; how to adjust three flat collectors

I do not agree with you in this case, construction expert.

The information from the Federal Health Office clearly states in this context, as reproduced here without omitting any lines or paragraphs:

Large systems are all systems with storage drinking water heaters or central flow drinking water heaters, e.g. in residential buildings, hotels, hospitals, and systems with drinking water heaters and a capacity of more than 400 liters or more than 3 liters in a pipe between the outlet of the drinking water heater and the point of use (cf. DVGW worksheet W 551).
Single-family and two-family houses are by definition not subject to the obligation to test for Legionella according to the Drinking Water Ordinance 2001.

In my, albeit lay, legal opinion, single- and two-family houses are therefore definitely exempt from the testing obligation regardless of the size of the storage tank.

If necessary, you should have this circumstance reviewed again by an administrative lawyer here, if not already done, in the interest of your clients who already have enough trouble in the present case.

Hello,

I do not share your opinion in this case, Bauexperte.

You don’t have to – it doesn’t change anything about the circumstances, because

If not already done, you should perhaps have this circumstance reviewed again by an administrative law expert for the sake of your builders, who already have enough trouble in the present case.

that will not be necessary, as the storage tank will be replaced with a smaller unit in the foreseeable future. If it were different, I would already be stirring up entire office towers

Kind regards

Ok, then it's settled anyway

I was just surprised because I had only heard about it and actually I should be familiar with it since I also have a 500l water storage tank myself (although I do need it)

[...]since I also have a 500l water storage tank myself (although I do need it)

Only drinking water storage tanks or combination tanks for drinking water and heating??

Only potable water storage tanks or combination tanks for potable water and heating??

Since it is a total of 500 liters, I assume that it is a combination tank.

Since it is a total of 500 liters, I assume that it is a combination storage tank.

Hmm - Do you have solar thermal (ST) for heating support? Then the 500 liters are not your drinking water, but the drinking water is heated by the 500 liters. That means in this case the legionella in the storage tank are completely irrelevant – so nothing needs to be investigated. (Regardless of which one of you is right *g*)
