max kw under domestic

[ollski]

Are we still limited to 70kw under ccn1?, I had a feeling it had been changed recently. I know I should know but I never see anything anywhere near that.

 

[Dan Robinson]

AFAIK yes.

 

[ianmcd]

yes its still 70KW I think what you are getting mixed up with is pipe sizes were increased in domestic scope to allow for larger combi boilers to be installed with domestic ACS

 

[ollski]

Ok whats the 135kw figure in my head?

 

[dcawkwell]

Never normally a problem.
As when getting to those figures multiple boilers usually become
a sensible idea.

 

[ollski]

true of course but I have a small office / factory looking at a demand of around 100kw, not sure if ccn1 covers me. If not any commercial guys near Bristol fancy a day of commissioning?

Could be clean air act but that's slightly more than 135
