How we can support your project

If you are a specifier, consultant or contractor, we have tools to help you get the best possible heating and or water solution for your project.

Spec Pro

Download a free copy of Spec Pro and it will help you select the most appropriate unvented cylinders from 70 litres up to 2,500 litres, solar cylinders, point of use water heaters, boiling water products, chilled drinking water equipment and hand dryers for residential or commercial applications. Spec Pro will guide you through the specification process and provide product specification information, images and CAD drawings, which can be emailed, downloaded or printed.


SIZE-IT is a water heater sizing programme to help you select a suitable appliance(s) from the Andrews water heater product range for a particular hot water requirement.  It is available to download free of charge here.  Photographs, CAD drawings and specifications of the selected product are available for you to include in your M & E design proposal.

BIM library

BIM stands for Building Information Modelling. BIM files include dimensions, pipe connections, outputs, efficiencies and weights. They allow you to develop a full virtual plant room 'walk through'. We have BIM files available to download for Potterton Commercial, Andrews Water Heaters and Baxi Senertec products.  Engineers can select and retrieve product requirements and import models directly into the BIM project they are working on.
