Central Heating Requirements Calculator
by D.J.Holden

This is a demonstration version of a central heating requirements calculation program. It works by asking for various details of the construction of each room in the house (the demo version can handle up to nine rooms). It then displays the heating requirement for that room in BTUs. Full instructions are available when the program is run.

The full version has a large number of additional features, such as working in Metric as well as Imperial, and calculating the heat loss through each part of a surface.
