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 It's very outdated.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 Heatup Only Mode there is no mode specific input with the exception of "Round Fuel Usage/h". This mode will simply take your boiler and calculate how long it will take to heat up, and how much of the selected fuel is required to do so. In addition it will also calculate how much fuel the boiler will need per hour of running on max heat.
