The Fernox Postal Sampling Service provides an invaluable facility for those who want to ascertain the cause of central heating problems and to determine the necessary remedial action required to resolve them, particularly where on-site results are inconclusive. Analytical water testing works because the water in the system contains all the information required for diagnosis of the most common problems. The Fernox laboratory will carry out a full analysis of the system water as part of the Postal Sampling Service, establishing the root of the problem and prescribing the correct Fernox treatment. Following treatment with Fernox products, the Postal Sampling Service will provide confirmation that the system has been correctly treated. This service is not available if competitor products have been used.
