I got this mod https://mods.factorio.com/mod/Advanced_Electric that adds tiered boilers, giving them a large bit more power output than this.

Would you be willing to do something about this?

I do not plan to add tiers of buildings to any of my mods. That said, I used the correct method of adding fire graphics for this boiler, so it's very possible that mod author could use their same algorithm that generates tiered fuel boilers to also generate tiered gas boilers. I would definitely be willing to make any little changes needed to support that approach, although it may be ready to go as is.

I'll go ask him then.

Thanks! This was meant to be basically a vanilla+ building, so I think activating tiered versions in that mod along with everything else he generates makes a lot of sense. I plan to support this mod as long as factorio exists, so I think it's a great idea.
