EnergyPlus results after using CHP

Hi everyone,

I used 2 Generator:MicroCHP to power a residential building, one for the floor heating and another for the potable water (here you can see the sketches of the loops), and I got this result :

That I find strange because, first when you compare to the results of the same building but without CHP (as shown below)

image description

We notice that it had an impact only on the water system consumption, and it had even increased (a little bit) the Heating consumption,

and second the CHP consumed a little amount of Natural Gas (0.12GJ) while it should the component that consumes the most, and we can see that the boiler (for the Heating) and the water heater (Water Systems) are consuming more Natural gas (respectively 48.25JG and 9.71GJ).

And mostly why I can not find anywhere in the results file what are the values of the heat and electricity generated by the CHP? andfor what is it used (if it has been used) ? I actually didn't find any relevant information concerning the CHP, except these two tables that I didn't get well

Did this happen before to anyone of you ? Does anyone have an explanation for it please? or an idea about what is wrong ?

Thanks :)

According to these two tables the CHP of the heating loop is not working at all, and the one for the water syst loop is working only on June and July!! Does anyone knows why ??

Did this happen before to anyone of you ? Does anyone have an explanation for it please? or an idea about what is wrong ?

Thanks :)
