Which is absolutely terrible as it is a rented property and I believe it is more important to do it then when doing a service.dont need to tt on land lord gas safety certificates

Also @ShaunCorbs & @firemant isnt what you are both describing a KW rating and not a gas rating. A gas rating for a 30kw boiler is about 3.2kw not 30kw? Or am I missing something here?

I mean that this is a gas rate mateI don't quite understand your post, HF.
Probably strictly speaking, a gas rate would be measured in M3 but after saying Kw is not a gas rating, you go onto suggest it is.
A 30Kw boiler will be typically about 31/32Kw input, not 3.2. was that a typo?
HF, apologies f I still have the wrong end of your stick
But my view is that what you are both taking about is an output rating not a gas rate.My figures are direct on the meter to give you x amount of kw
But my view is that what you are both taking about is an output rating not a gas rate.
But when wou ask a manufacturer’s The Gas rate of their boiler I.e a 30kw they will tell you it is 3.0 so .100 x 30 = 3.0It is a gas rate (meter) comes out at 30kw
Eg
004.10
004.20
On the meter
But when wou ask a manufacturer’s The Gas rate of their boiler I.e a 30kw they will tell you it is 3.0 so .100 x 30 = 3.0
I get that, but when you do this calculation 2.8 x 10.65 = 30 ish kw. The end figure which is 30 kw is not the boilers Gas rate it is an output rating.Or 30 / 10.65 2.8m3h
I get that, but when you do this calculation 2.8 x 10.65 = 30 ish kw. The end figure which is 30 kw is not the boilers Gas rate it is an output rating.
My point is, that this is an input/output rating dependant on how far you got with your calculations and not a gas rate.its not hard if you know if you dont
write the number down time then write the numbers down work it out from there or time it if imperial
or if you do know what kw should give you like
.10 is 30kw
.095 is 28kw
.08 is 24 kw
.05 is 15kw
I think we are arguing the same thing mate. But I call the figure in the bold circle the gas rate and the figure in the thin circle the input/output rating. Ignore the exact figures I wasn’t getting them from anywhere they were just random figures

I don’t have one it’s been a long day. Sorry mate.Blimey, HF, they reckon a marathon is hard work .
Yes, the 30Kw (thin circle) is the nominal output - but I don't really get your " input / output rating" description. it is simply the designed Output.
The (thick circle) IS the nominal Input, therefore the "gas rate" you are looking for. However, most of us, I think, would present the "gas rate" in KW/hr's.
So, yes, essentially we are in agreement.
What was your question?
I understand that mate. But what I was saying is that at college here. We are taught that the gas rating is the lower figure and the output rating is the higher figure. That is what I was saying.Input/output are 2 different things on that data badge
That is a 24Kw boiler? The 24Kw is the advertised OUTPUT, but the actual MAXIMUM OUTPUT, as it happens, is 24.7Kw.
(Advertising a 24.7Kw boiler as such is not as snappy as saying "24", although I do not know why they don't just do the data plate at an Input relating to a 24Kw output. But they are not alone)
The MAX INPUT is 25.7Kw. The boiler is range ratable, between 11Kw and 25.7Kw INPUT. It is this range which you would be looking for, and verifying against, when as rating.

I’m too tired to carry this on mate. I will just agree with you.Back to front, HF. Or is that a typo.? Are you still training, HF?
The Gas rate is the Consumption (Input) (higher figure), which HAS to be greater than the OUTPUT (lower figure).
(I KNOW, before someone comes back with 103% efficiency )
I’m too tired to carry this on mate. I will just agree with you.
Mate. Let me explain this to you. Either we have got crossed wires here or it is not me that is wrong. What it sound like you are talking about is a equivant heat input. (Not a gas rate) a gas rate is how much gas an appliance uses in 1 hour, not the figure you get once you times this figure by 10.65, or whatever calorific value you are using. (This figure is an input rating) I cannot explain it any clearer. The diagram below if the best I could find.Okay. But you really do need to know. It is actually not difficult. You need to speak to your trainer, if you are, in fact, still training.

I’ve been qualified for 12 years mate. Not ages but long enough.Okay. But you really do need to know. It is actually not difficult. You need to speak to your trainer, if you are, in fact, still training.
Until you are trained you will never know mwaw wa wa wa waI’m a training gas engineer what is this 26.9 you refer to ?
3.2 M3/HAlso @ShaunCorbs & @firemant isnt what you are both describing a KW rating and not a gas rating. A gas rating for a 30kw boiler is about 3.2kw not 30kw? Or am I missing something here?

Nice edit.3.2 M3/H
