Using anchor bolts in concrete wall of a modern appartment.The boiler is 34.5 Kg when full.Want to know which bolt is best.The unit requires four screws.
Check the installation manual. It will be in the section Mounting The Boiler . You can't build a shelf under it as the piping exits the bottom.
No offense at all but I'm curious as to how you define concrete, be it poured/reinforce wall panels, or Block? I won't even bother doing a conversion, but I know WATER weighs 8.5 POUNDS per gallon, and you can add the capacity to the weight of the Unit. Certainly too, not knowing the size of the attachment plates or how they might be fixed to the boiler, IE: Welded, I suspect something more substantial than SCREWS, IE: 3/8th inch by 8,10,12 inch concrete anchors, fit into pre-drilled holes, that expand as a NUT is turned at the facing threaded end. I use them to support Tonnage in second level decking and Lofts. MODERN apt. I assume is an issue then of aesthetics, though a Boiler should probably be hidden, or at least covered by something ones grandmother once crocheted as a table cloth. Beyond that,,,MODERN has no strict correlation to the substance/strength of the wall, or construction of the structure. There are all over the planet, thousands of structures, that were BUILT thousands of years ago. To truly suggest an option I'd consider, would include knowing the floor level, IE: basement, third floor , etc. and BUILDING a support device beneath the boiler. Steven Wolf Just my two sense
