(see new Heat Flow sheet below)

The following calculator has been designed as an educational tool to demonstrate some of the main factors that affect the energy efficiency of a heat pump system. It is hoped to be more informative than perplexing, however, due to the many variables, it can take some time to understand it fully.

The simple version is available, and recommended first. (see below)

At present, the files are only available as a download in Excel format Pictures of the files have been pasted below.
