All Heating Flushes include pre-flush assessment of your heating system using chemical testing for iron oxide, copper oxide, corrosion inhibitor, PH levels and TDS (total dissolved solids). Temperature reading are taken from every radiator to identify areas that may require extra attention. The tests are repeated at the end of the power flush and all results are compiled into a comprehensive report sent to our customers approx. 1 week after the flush date. This report can be used to satisfy your central heating maintenance provider or used as part of a home sellers pack.
