Commercial job completed with 2 x Vaillant 64kw boilers running through a vaillant plate to plate heat exchange, keeping the boiler circuit separate from the heating circuit @vaillantuk
..and the mist his current boiler runs at is 20kw ๐คฆโโ๏ธ, told him that's because it's undersized and I'm not willing to quote a replacement keeping the existing gas supply, even a 28kw would be undersized when I calculated the pipe run, some people can't be told
Just been to quote a vaillant lead to remove an 837 and replace with a green iQ 35, explained to the customer the gas is currently undersized and needs minimum 28mm judging by meter distance, he argued it out with me the entire time saying his boiler will never run at 35kw....
