How to sell a boiler II

Does not bother me much as I am to fit another IG later this week!
Why do you keep mentioning your fitting an IG next week for , maybe your way of advertising again again ;):rolleyes:

Bernard why are you so keen for Dan to prove IG efficiency rating when you have fook all to do with them and never even seen one , from your arm chair why don't you study your JS boiler as you seem to think it's the bees knees with your super duper hw cylinder :ROFLMAO: what's your systems efficancy rating:ROFLMAO:

It annoys me that marketing people make false claims when selling items taking advantage of the fact that the average customer has little if any knowledge of the science involved in the appliance.

All I asked for was an explanation of the maths that turn the maximum possible combustion efficiency of 99.99% into a value of 122%.


UPDATE, it seems that a new value for efficiency in domestic hot water is being quoted 127%

The ErP data in the manufacturers installation is Europe wide and standard supposedly so a sort of level playing field will exist. Find that page and you can compare to other manufacturers.

VC although the Kiwa certificate is not there, take a look in the appropriate CCR folder.

Blowhardgreen isn't the only one with secret Internet hidey holes :p
 
:mrgreen: please remember boiler makers can quote an efficiency which has been established in a test situation but ****whits fiddle feckers google whackers have been known to add diydafty fittings to systems and still expect excellent efficiency,

Maybe add a vent,

OlsAndBold.... what has the plumbing configuration have to do with the equation.

Efficiency of boiler = ( Heat into water through boiler / heat produced by burning gas ) * 100.

The way I plumbed my heating has nothing to do with the way a boiler's efficiency is measured or calculated.
