Bis letztes Jahr habe ich in Wohnungen oder Studentenwohnheimen mit zentraler Warmwasserbereitung gewohnt. Letztes Jahr bin ich in eine Einzimmerwohnung gezogen. Da ich alleine lebe, lag mein anfänglicher monatlicher Kostenvoranschlag von E.ON bei 70 €. Sie haben mir jedoch vor Kurzem eine neue Abrechnung zugesandt, aus der hervorgeht, dass ich letztes Jahr rund 7.000 kWh verbraucht habe, was meinen neuen Monatspreis auf 230 € erhöht.
Ich war schockiert, genau wie alle anderen, die die Rechnung sahen. Obwohl die Energiekosten normalerweise hoch sind, war dies extrem. Erst als ich es mit anderen besprach, erkannten wir den Schuldigen: meine Badegewohnheiten. Ich benutze die Badewanne jeden Tag, manchmal sogar zweimal am Tag. Es war ein großer Schock zu erfahren, dass die Nutzung von Warmwasser oft so viel kostet. Obwohl ich seit fast 10 Jahren in Deutschland lebe, war mir nie bewusst, wie teuer es sein könnte, weil ich immer eine zentrale Warmwasserbereitung hatte.
Der Gesetzentwurf des vergangenen Jahres hat mir die Augen geöffnet, und ich bin verwirrt darüber, wie ich vorgehen soll. Endlich verstehe ich den Unterschied im Energieverbrauch zwischen einer Dusche und einem Vollbad. Es war einfach etwas, über das meine Freunde und ich noch nie zuvor gesprochen haben. Damals, in den Studentenwohnheimen oder WGs, wo die Miete pauschal gezahlt wurde, musste ich 20 bis 25 Minuten lang duschen oder Wasserwannen nehmen. Welche Gewohnheiten sollte ich ändern? Ich möchte sauber und gesund bleiben, ohne so viel für Strom auszugeben.

I shower 5-7min and I’m clean?
Well, there is no contradiction. A 5 min. Shower should get u clean. The other 20 min have no effect in my experience. You can also adjust the water pressure to consume less water over time.
If you need to have a bath up to twice a day to stay clean you‘re either doing things getting you very dirty or suffer from a condition that should get some medical attention.
Shower once a day tops. Sometimes every two days is sufficient. But only if it isn’t hot outside, you haven’t done sport and only sat inside. It’s also better for your skin. Nobody needs half an hour showers or daily baths to stay clean and healthy.
EDIT: Also have fun with your Nebenkostenabrechnung due to your daily water usage.
Looks like you already have the answer: Shower instead of bathing, with warm water instead of hot.
Bathing twice a day … And asking for Change of habbits.
How about showering once a day about 5-7minutes.
You take a full bath once or twice a day? Just shower once a day. Rinse off a second time (or third time….) in summer if necessary.
7000kWh is extremely high for a single person, even with a Durchlauferhitzer. I had those in multiple flats for about a decade and never got even close to that .. while hosting servers at home (-> Pure electricity sinks).
My usual usage was 2500kWh, and that’s already with 800 – 1000kWh for servers.
Do this: Read your electricity meter, then go for a shower or tub. Afterwards, read it again and you’ll know how much you just consumed. With that you can investigate further if your usage is just that high or if there’s something else going wrong.
**Edit later**, as OP goes through about two full hot baths per day (!!).
Let’s do some quick math: 7000kWh per year, 1500 of that assumed to be „normal“ use. 5500kWh per year for hot water, that’s 15kWh per day or 7.5kWh per cycle. At 24kW that’s about 20min of usage at full throttle of that heater which sounds about right when letting in a hot bath.
So, yes, OP, your use is just crazy outside the norm, and yes, those 7000kWh sounds „reasonable“.
A nice shower of 5-15 min per day is easily enough to „stay clean“.
A shower daily is alright, sometimes even necessary. But a full bathtub, what kind of luxury is that.
5 mins is plenty in the shower, tf are you doing there for 30min
I take 20min from waking up, to showering, eating, packing and leaving the house in the morning…
Jesus. A full bathtub of warm water, twice a day, electric water heater? That’s insanity.
Plus with a short shower, you’ll also save a bit on your water bill. Water is not a perpetual resource, even when Germany as a whole seems quite rainy, we experience periods of drought more and more often and many places enact water use restrictions. That’s just going to become progressively more commonplace.
You have about double the amount of kWh then we do as a family of 4.
Doing a bath every single day and even twice a day is, beside the high water consumption (you will pay for this too), really a big problem when you just have this heater. Instead of a bath, you should just take a shower most of the days (and keep it short).
Id probably just shower once maybe max twice a day each for no longer than 10 minutes and then limit the bathing in a bathtub to once or twice a week if you really like them. Use warm and not hot water (I never use above 39 C)
>While energy costs are usually high
They’re not, you’re just using a crazy amount of energy by filling a bath tub twice a day.
>What habits should I change?
Shower max. 15 minutes a day with the water on (this means that if you shower twice a day, 7,5 minutes each shower). Turn of water when you are wahsing your hair or soaping up, turn it on only to rinse.
I only shower 3 times a week (the others days I clean myself with a cloth but that of course uses little hot water), that keeps me clean enough but I have an office job with air conditioning, if you have a job e.g. outside doing heavy lifting that might not work for you.
you should practice learning about showers.
> I used to take 20 to 25-minute showers or water tubs. What habits should I change? I want to stay clean and healthy without spending so much on electricity.
Thanks for the laugh.
you live in decadence, and complain about the high living cost?
A bath — sometimes twice — aday? I haven’t bathed in years – unless you count the communal swimming pool twice a week.
A 10min shower works perfectly fine. Stop wasting so much water.
>I use the bathtub every day, and sometimes twice a day
> I want to stay clean and healthy
Are you aware that excessive bathing is not making you more healthy, but can damage your skin?
Even showering daily is not really the best but i do this too. But up to two full hot baths every single day?
> I want to stay clean and healthy without spending so much on electricity.
Chances are you’ll be just as clean and with healthier skin if you just take a short daily shower.
7000kwh is definitly a lot, even when its combined for all Electritiy (not Warm Water alone). 7000kwh * 0,30€/kwh /12 Month = 175€. And that is without Grundgebühr. Is the invoice for the full 12 Month?
Do you have an elektrical Heizung, too? Turn that off during summer. An seriously a full Bathtub TWICE a day is insanity. Shower. And take a bath on weekend or someting.
OP, I’m far for being an ecological extremist, but you’re just having a wasteful lifestyle in terms of electricity and water.
This is absolutely insane. You have spent the water resources for a whole household.
I would sentence you to a one week hike where you have only access to fresh mountain water. You’ll definitely understand how precious fresh drinkable water is which you were using all the time btw.
some places even in Germany suffer from dryness, some people in Europe suffer from lack of drinking water. Just leave alone the rest of the world for now.. and you’re just using like 150-300 liters a day just for showering / bathing.
Let’s say every week you took at least 10 baths.
In a year that’s around 72.000 liters of water.
In your 10 year bathing journey that is around 720.000 liters of water.
And bathing / showering usually is around 30-35% of your total water consumption, so the rest still adds up to that.
+ The energy to heat the water.
That’s indeed something that don’t add up even if just a few percent of us act like that and they just showed you with that high electricity bill.
My skin could never. I’d be shedding like a snake if I took a hot bath twice a day. I’m actually a little impressed.
20min shower??? What are you doing in there?
