Our pipe calculation is performed using ISO 12241 second edition (2008-08-15). Where appropriate reference values are taken from this document. This calculation has been validated for pipes with internal temperatures above ambient only (that is heating, not cooling)
This calculation requires an empirical estimation of the insulation surface temperature to calculate Hse which is then validated against outputs. To process this step we calculate all suface temperatures between ambient and pipe temperature at 1 degree C intervals and check for the best match.
Detailed diagnostic information is logged by the program code at all stages of the calculation for each pipes and is available on request. However because of the techincal nature of this it is likely to require some help with interpretation, so we do not enable viewing by default,
