How much water?

Could someone tell me how many gallons of water it takes to fill a EFM-520 boiler?

About 41 gallons

Thanks! Stoker-Man.

Hey Heaterman... Off topic but I also have a Bixby 115 but I only used it a handful of times this year until I started the boiler up... I have used it the 3 years prior to this one though and like it.

Stoker man correct me if I am wrong but didn't the older tube boiler's hold less water then the newer flat plate heat exchange boilers say from 66 67 to present and the older tube boilers from 66 65 back to 48 The 520 high boys I know the bigger 700 900 1300 had both types I seen a 1300 1963 with the flat plates but also seen a 700 1966 with tubes .
Anyway I now the 520 tube boilers hold 40 gal except for the high boys they held 74 Gals also seen 350 come with both
types tubes and flat 29 gal and 30 gal

I'd have to look around for that info, coalberner.

I got a 1960 Flat 520 and a '66 flat 350. Scott
