Question about burner pressure

[lightning]

Hello

If i have a range rated boiler of

12 kw 15 kw 18 kw

10mbar 13mbar 16mbar

if i check burner pressure and it comes out at 13mbar

but gas rated it at 18.1kw.

Then i am thinking that the injector is wrong size or has been enlarged .

is this correct.

would have asked big brother as he is not here,i am only 16 and eager to learn thanks

Is the 12/15/18kW the input or output of the boiler?

 

[lightning]

its the input of the boiler

Hello lightning,
Big brother is the one to speak to here.
Ask him about net and gross.
Input and output
Heat into water.
And all the other terms that may confuse you and indeed us sometimes!

Good luck,

Matt

18.1 Kw input sounds about right for 15 Kw output to me.

Sounds about the right ball park
