Domestic / commercial borderline

[newcastle phill]

Had a call today regarding an ideal imax 45
Obviously from the ideal commercial line of boilers at least in terms of build quality and durability
Right next to u16 meter. No other gas appliances at all
In small offices.

Now boiler is 45kw
Quick calculation of IV of meter and pipework is still within /up/1b

This can still be worked on domestic ticket ???
they only wanted radiator adding to a room but i noticed the annual inspection was out of date
didnt know wether it was worth pointing that out when i wrote quote up and adding that asan addition

So its under 70kw (domestic limit)
Room sealed
And iv of pipework for purging etc is within 1b


Ta muchas

Under 0.035m3?

U16 is 0.025m3.

Yes i asked to see the boiler as when they phoned and they said they were in offices, my initial thoughts were walk away. Systems over 3 floors and i dont know if i can be bothered.

So the conversation went ( before i knew the details).... i said does it look like a one in a house, you know a combi, she said yes but a bit bigger, so off i trotted and measured room up and looked at boiler, u16 right next to boiler within 1.5 metre on 22mm.
Well within 1b for 0.035

 

[newcastle phill]

I suppose my salient point being.....
If the criteria falls outside of 1b that then defines commercial ??
Not necessarily the definition of the appliance itself as commercial...?

ie upto xx kw
<0,035
<= u16
Etc etc

<0.035m3 and <35mm pipework.

But the boiler is classed as commercial even though it's under 70kw.

There's your get out......

Hmmm i need to look into this further. Obviously i am trying to clear up exactly what defines the fine line.

It falls within bs6798 asfar as ive read.
And its within igm up 1b.
I realise its in offices AND am still reading as im bored

Think ill call gas safe and just enquire further.
On the face of it its only slightly larger than a large typical domestic boiler
And well under 70kw.

Its a job i dont want BUT i just want to fill the grey matter with more useless info Ha

 

[newcastle phill]

Just regs are bloody annoying, nowhere it is easy just to find a simple answer to a simple question, considering there are no typical domestic boilers that go upto 70kw that ive seen generally then 6798 seems silly in that regard ??

I have phoned gas safe on this exact issue, I got told if MI or manufacturer state it's a commercial boiler, it doesn't matter what KW it is, then it requires relevant commercial ticket.

Having said that a mate phoned some time later and got the usual cop out, I've always taken the former stance though.

 

[newcastle phill]

Wheres kirkgas these days lol

Gas safe have told me in the past that if the manufacturer refer to it as commercial or state any commercial regulations in the instructions then you cannot work on it with just domestic qualifications regardless of if it is under 70kw.

 

[newcastle phill]

Seems to make sense except the MI also make reference to domestic standards too.
In particular forbthe 45 and 60kw variants !!

+1 but thats the way gas safe are 😀

Agree as above if the manufacturers state its commercial appliance then said tickets are required some gas fired water heaters are well within domestic KW yet are classed as commercial appliances.
