Interestingly intergas did say if I recall correctly the only other manufacturer that came clise to the same efficiencies were Atag.ATAG compact boilers are the most energy efficient in Europe and can significantly reduce your energy bills by up to £570 a year*
From their website, someone telling porkys! But who?
Whoever of the two is in fact more efficient the point is they are both significantly more efficient than worcester bosch, Vaillant, Ideal, viessmann, baxi, Ariston, etc.
