Hello,
There is a mystery at home, with my consumption of the electric boiler.
My electric boiler, makes 200 liters (it heats at night) (bi hourly meter)
But it is horizontal, because of the height of the cellar where it is installed
My electric boiler is powered by the solar boiler ... (also 200litres)
So when I take hot water from the electric boiler, I bring in hot water from the solar boiler ...
These days, my solar boiler is at 70 ° c (+ -)
Yesterday, I just took a bath, and I saw again the number of kw / h that my electric boiler took at night to get back to T max.
Result !!!! 5kw / H.
Theoretically, apart from the losses, I should have consumed 0 kw / h
I saw on a site that to take a bath, it takes 5KW / H.
So, I don't understand anything anymore ...

Here is the site, it is good, at first sight.

Attention, it's pdf

I forgot to say: my electric boiler is lime-free (rainwater),
The distance between the two boilers is + - 10 meters in insulated 22 mm diameter copper pipe

your story is weird enough.

How do you measure the consumption of your boiler?

- 1 liter of heating oil costs 0,30 Euros.

Interesting but a little "outdated" no?

Do you have a PM230 or LeJuste equivalent?

Totally agree with you ... amazing
To measure the consumption, I have a "gadget" like christophe sells, named cost control ... (you place an appliance between the socket and the boiler, and it tells you how much kw you have consumed, ...
For me, these are the losses due to the insulation of the boiler, which is very bad

Is it a Chinese Cost Control?

Before panicking I advise you to check his calibration... with a device whose consumption you know exactly.

Style 1 toaster.

Good idea Christophe

or to schunt your solar boiler and measure the consumption under the same conditions

5 kw / h per day just for losses it would be huge, it would be 1825 Kw / h for a year.
Almost what my parents' new boiler consumes each year. he was changed 4 years ago.
