Hi!
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 It's very outdated.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!

In Time Simulation Mode you enter the specific time you wish the boiler to run for. It will then tell you how much fuel was used during this period in total, and if the boiler was not fully heated when starting it will tell you the portion of fuel used during heatup. In this mode heatup can only be disabled by setting "Starting Heat Level" to the maximum temperature of the selected boiler type. The time input also accepts decimals, so you can for example enter 0.5 in the "d(ays)" field to have the boiler run for half a day.
