Iberdrola bill

aadebbah, thanks for uploading the billing details. Wow !  on the potencia level.

What form and extent of heating do you use and is any of it of the underfloor heating  type ?

Nothing particular , I must think it was applied when I just bought the house and did not know much about types of contracts ...

It was not me who asked for the 9.2 potencia which I think for my use is far too high I must agree 

Thank you very much for your comprehensive analysis and advice . 

First thing I am going to do is to lower my potencia , to 5.75 as you advised , then I will continue to monitor the bills to gain in efficiency .

Good to have people like you around to advise .

Hi everyone ,

I have applied for a change of my potencia from 9,2 to 5, 75kw  Online 

They sent me Right away the new contract 

And apparently they will charge  a fee of 10,5 € for the change ...

My new contract states that it is a normal one , with the new potencia contratada of 5750 W

Tarifs de  accesso : 2.0DHA , modo 1 , don’t know what it means ....

Tension :1X230V

Empressa distribudora:I-DE,Redes Electricas intelligentes SAU

That’s my new contract that I have to sign and return to them .

Just for info, and to explain the seemingly odd potencia of 5750w, it's due to nothing more than the rating of the breaker on the incoming supply i.e. 5750w / 230v = 25a. 

For your current 9200w you will have a 40a breaker, 9200/230 = 40a.

Smart meters will handle it a bit differently and more strictly possibly leading to trips where a mechanical breaker might  have hung on a fraction longer under transient or minor overload conditions. 

hi ray

is the potencia of 3.5 suffice for a 2 bed, 2 bath apartment ?
