Central Heating - Expert Assistance Required

[Doctor Drivel]

..and you are one of the biggest dribblers.

[Doctor Drivel]

...you are here, the so called boiler expert. The one who didn't know condensing boilers are rated up to 109% efficiency. He was told and still wouldn't believe it. Expert at boilers and doesn't know something fundamentally simple - yes sure he is an expert. More like someone who just picked it up - a little knowledge is dangerous. I have no time for people who make their living in a field and don't know it.

[Doctor Drivel]

I know what you mean it is difficult to get rid of idiot Plownman and half-wit Matt, et al.

The physics illiterate strikes again...

[Doctor Drivel]

Another effing senile idiot.

No! it is just the rather crazy way efficiency is calculated for boilers. I read about it some weeks ago, but it seemed not a crazy as it sounds, and did not understand it.

[Dave Plowman (News)]

Efficiency is simply energy in versus energy out. And since energy can neither be created or destroyed efficiency cannot exceed 100%. As I'm sure you know.

But Drivel doesn't understand this since he can only read adverts.

[dennis]

Yes.

It is quite possible to be 109% efficient.

Take the case where the supplier is moving slowly while the consumer is travelling at 0.99c and do the maths.

As time passes slowly for the consumer he will use less energy than the supplier ships.

[Doctor Drivel]

This man has not a clue about boilers and how the efficiencies are calculated. This is the idiot whop told people not to service their boilers, because the fool never did it for 18 years.

Sad but true.

[Doctor Drivel]

..here is a man who doesn't know, a man who has no clue ..he has no clue about the things which are known to me and you

..permanently vacant in his head ..no knoweldge, reason, logic, this must be said

..drivel and babble it just come so ..relentless, incoherrent in it flow

..it's time take no notice of this fool so clearly senile ..just thank the Lord you are sane and give a little smile

[Dave Plowman (News)]

I understand perfectly how efficiencies are calculated.

That you choose to believe an inaccurate method says more about your lack of basic knowledge than anything else.

It's up to 18 years now is it? Another example of plucking figures from the air and quoting them as if they are true.

Are you drunk again?

[Doctor Drivel]

It is clear you don't. And when expert tell you otherwise you persist in saying you are right. You a senile idiot.

The message from Dave Fawthrop contains these words:

Its just a con trick including an element in the numerator which was excluded from the denominator.
