BTU Calculator app for iPhone and iPad

This BTU Calculator will help you select the correct size radiator for your room.

Just enter the room dimensions in either feet or meters then select options for the room, such as:

The Room Type
Wall Insulation Type
Which Way the Room is Facing?
How Many Outside Walls?
Are the Windows Double or Single Glazed?
and does the room have French Doors?

Hit the Calculate button and the app will show you the BTUs (British Thermal Units) required to heat the room. Also it will calculate the number of Kw too.

This app is under constant development, if you have any ideas on improvement or encounter any bugs, please let me know via my website www.timothyredman.com.
