The Fernox System Health Check is a premier postal diagnostic service for analysing central heating system water quality. This service provides accurate laboratory results to identify debris, cleaner residue, or incorrect dosing, ensuring optimal system performance. Easy-to-follow recommendations are provided in a detailed report, with results accessible online for added convenience.

Simply fill one sample bottle with system water and the other with mains water (i.e. kitchen tap), complete the enclosed order form and return the samples and questionnaire in the Freepost envelope. The results will be returned directly to the customer.

Interpretation of the results is based on the samples being representative of the system and treatment being with Fernox products.
