Hello,
There was a kind of slime in my boiler's drip tray today? That's definitely new, otherwise it's just water. I tried to clean it away a bit. There's been construction work in my building for the past three weeks. Could this be related?
Is this a concern? What could happen?

Loading...Good evening, Due to a burst pipe, the water in the street was turned off for several hours. It's flowing again now, although a tap that was working fine before has barely produced any water since then. What can I do here? Should I just let the water run and wait (a friend's tip)? Or…
I checked my bank account today and noticed that I haven't had a bill for a few months. Then I checked the Enercity website, and it said the next bill is listed as €0.00. Now I'm a little worried that there's been a mistake. I've already sent them an email, but does anyone know if…
What is the symbol on the Ökonox boiler? And how do I set the heating? Unfortunately, we don't have any instructions.
Hello friends, The following problem: I own an apartment in a building with 24 units. The heating in all apartments suddenly stopped working, except in mine. A few weeks ago they were still working because my little son had turned up the heaters in the kitchen and bedroom. I turned them off again and that…
Is this about the electricity costs?
A wall connection had become leaky and was therefore replaced. So far, so good; it's the connection where the water from the hot water boiler disappears back into the wall. Just to be on the safe side, I checked the water meter. I noticed that the meter was moving forward and backward. It moved 2.5…
Looks like residues that have dissolved out of the pipes. This happens when the water was turned off and the lines were temporarily unpressurized. When the pressure is rebuilt, it removes smallest particles from the inner wall of the pipes and, if necessary, also from the boiler and flushes it with the places where water is removed.
This is completely normal and harmless. You should also screw the beaders on your water taps and the shower head and, if necessary, clean them, as these particles could have been collected.
okay, thanks – this hot legionella can’t be that? had never done that for that I can hardly guess that
No, Legionella isn’t, but you can be sure to be protected by turning the boiler to maximum temperature in between. That should be 70°C. This is then a thermal disinfection. When the water is heated so strongly, turn all hot water taps up and run for a few minutes.
Legionella can’t be seen. You can infect yourself with legionella in the shower, because you breathe very fine, possibly contaminated “nebel”.
Legionella do not reproduce in cold water. The water is cold until you enter your boiler. If you regularly shower, any Legionella that is present cannot multiply so strongly that they become at risk. But if you’re gone for one to two weeks, you should always be as safe as described above. Then you’re on the safe side.
Normally, in central heating in multi-family houses, the service water is heated to 55° C. to prevent Legionella formation. In the detached house or just as with you, in the case of boilers in the individual apartments, you can also get out at 45 °C. This significantly reduces energy consumption. But then repeatedly turn up to at least 55° C. or even 70° C. to reliably kill other germs.
Legionella testing is required in multi-family houses with more than two apartments only from a certain length of pipe between the central water supply and the individual apartments. However, if the apartments are only supplied with cold water and then heated in the apartment with continuous heaters or boilers, no Legionella testing is required for good reason, precisely because the danger is too low. This can also give you additional security.
So, now I have explained the subject quite in detail and hope to have helped you with it.
Please.
thank you for the detailed answer! that really helped! beautiful day still to you!
