What is the formula, indirectly refered to by the (hi) modifier that takes the data for the actual efficiency achieved during testing and from that data produces the 127%(hi) or 122%(hi) values.

It is possible to fiddle factor results, some potential customers will believe the impossible has happened. Potential customers with even the minimum scientific knowledge will not accept the fiddle factored efficency claimed if it is more than 99.99%
 
Navitron Systems. Auto pilots and othe navigation equipment.

Maybe someone is looking for some guidance.......
 
And what's the specific efficiency being tested numb nuts?


I think you'll find that for most manus the new range of boilers that are being launched will break the tests that were designed for older models

As I said if you have an issue either make a formal complaint or contact the test houses yourself directly and ask them to verify the results
 
Sorry explained it wrong. Under working conditions WP, the drop will be more then 1mbr. But the difference between the meter will still only be 1mbr.
OK, shall we leave it at that? I think we've kicked this to death! :(

MOD: Agreed.
