Real world vs theoretical hot water temperatures

Nominal is 2.5 m3/hr for my boiler. I haven't checked it though.

You don't need the gas rate for the temperature rise calculation though. You only need the KW rating of the boiler.

BTW, it should have been 38k, but then, I have taste. Would never spend money on a Bavarian tractor.

The boiler manufacturers do not use the gas rate when calculating the 35 degree rise. Please show me the calculation that incorporates the gas rate.

!!! i can hear your keyboard going like the clappers try again . OH , YOU WILL NEED TO DO A GAS RATING

What exactly do I need the gas rate for though? I don't think you know what you're on about yourself here. You don't need to know the gas rate to work out the 35 degree rise or the rise I have calculated for my 8 l/min instead of the Vaillants 9.4 l/min rating.

It gets better

8 litres @ 35 kelvin?

2.5 cubes?

I think Mr boiler is not working quite as you would like... but then if you stopped being an arrogant twart and did the gas rate like you've been told you might get the figures required.

Wonder if NETT or GROSS might have something to do with something ??

The boiler is working really well thanks. It's getting a 42 degree rise at 8 l/min.

So you don't know how to work out the rise then?

 

[AGAS]

its not straight forward as you think is it . surprised you haven't worked it out yet ? , you are a EIM ENGINEER after all . back to drawing board
third try ?
actually i'll help you a bit . got to work out as dan has said gross & net

Tell me how you work it out then as you are an RGI surely you know this kind of thing?

So you don't know how to work out the rise then?

Well you're not taking 2.5 cubes are you?

Oh, that's right you're too arrogant to go and measure it.

So you don't know how to work out the rise then

Yes we do thanks.

Tell me how you work it out then

Its quite fun watching you try and work it out without measuring.

How do the manufacturers work out the 35 degree rise incorporating the gas rate? If you're preaching at me then you must know that?

You seem unable to understand that the boiler power is only at 24 kW etc. WHEN its operating correctly.

To check if it is operating correctly you need to do the gas rate.

I feel that I have already explained that before!

I understand that but if it's achieving the manufacturers stated temperature rise then it must be pretty damn close to operating correctly.

Suppose its consuming DOUBLE the recommended gas rate?

But the DHW heat output is only half of what it should be because of a fault?

By your attitude you would never know!
