So, this site is incredibly old now. It was first created in 2013, and has changed quite a bit since then.
While it works fine for the most part, I hate it a lot. It's very outdated.
As a developer I've learned a lot of things since I made it. And I would not make it like this now.
So, I want to ask, would you like a more modern version of the old faithful Boiler Calculator?
This version will continue to be available, but I'd like to also provide a better, more modern version.
Please fill out this survey
to help me decide!

Fuel Simulation Mode lets you input a specific amount of fuel and see how long the boiler will run. In this mode each phase can be disabled by unticking the respective checkbox. Fuel is input in either of the two boxes. The first represents stacks, and the second single items. Both accept decimals, so you can for example enter 0.5 in the first box to get half a stack (32) of your selected fuel, or enter 0.5 in the second box to run on half an item.
