Re: How much more nuclear power plant for electric rolling?

Nevertheless, the strong power variability of nuk power plants is a tangible and measurable reality.
we can make all the long speeches, the facts are stubborn.

Re: Economic analyzes on the passage from 90 km / h to 80 km / h in France ...

the reasoning is quite capillo-towed. the additional time spent in transport is not at all certain contribution because on a given route, the pieces where we will drive at 80 instead of 90 will be limited, moreover what says that the decrease in speed will not promote traffic p ...

Re: Bilibino, the next nuclear accident ??

we will perhaps avoid the accident at bilibino if the floating power station arrives before all the ground has melted around bilibino. : Cheesy:
or else, the accident will be the floating power station.

Re: The car of the future

yeah, blah, that doesn't mean much. a journey of 4 km is absolutely not representative. when the fact of not using the eco and B modes, it's your choice but that does not mean that you consume less thanks to that. mode B is essential in my mountainous region to have fr ...

Re: Okofen “smoke vent” boiler problem

no, the problem is different. if it was too much pellet supply, you would not get the error message on the smoke fan. As DID67 said, the problem is a lack of combustion chamber vacuum. it can be full of things. if you're sure it's not partially ...

Re: Is Linky more accurate?

on the one hand there is a "smoothing" of the instantaneous power to take account of peaks, for example when starting motors, etc. tests reported by a user on another site speak of a smoothing over a hundred seconds. moreover, there is also a tolerance on ...

Re: Heating curve in wet weather

The only way to ensure a constant temperature inside whatever the outside conditions is the indoor thermostat associated with a boiler (a little) more powerful than necessary. The other methods (external probes, heating curve, ...) make it possible to minimize consumption ...

Re: Heating curve in wet weather

the heating slope has little to do with humidity. the thermal losses of a building are proportional to the temperature difference between inside and outside as a first approximation. a little increased in case of winds but humidity, I do not see. on the other hand, thermal comfort ...

Re: Need advice ... What settings for a pellet boiler?

I am also surprised that the manufacturers did not include a diaphragm on the air intake to slave the air fan to the flow so as to compensate for the pressure drop variations.
a diaphragm is a simple and fairly reliable element widely used in industry.
