These Giannoni heat exchangers are plentiful and are in millions of

Even Heatline, BIASI and Ravenheat have models using this heat exchanger.

Dunno about Heatline but saying "even" BIASI and Ravenheat use this HX is
like saying even Poundshop and Costcutter stock a product: it says cheap
tat not high quality.

Well Vaillant use the same heat X. These companies use this heat X in their
up market models. And in the case of the Heatline, who use industry
standard parts, it is cheap for what it is. Many of the parts use in these
boilers are used in more expensive makes.
