Irrespective of the way of getting thermal energy (gas, district heating, etc) or the fact whether a single or double pipe system is being used, heat is mostly transferred via common consumer water or chemically treated water. Since various metals are used in the heating system (sheet metal/cast iron – radiators, steel – pipeline, copper – heat exchanger), sediment forms as a result of electrochemical corrosion (various metals reacting mutually) when using both the waters, depositing unevenly in the pipeline, radiators and heat exchangers. It’s a sticky blackish mass forming an insulating layer in the system, heating through which will increase heating costs considerably. Also the power consumption of the circulation pump of the heating system will increase, since there’s higher resistance in the system. For instance, in the case of a 6,000 m2 building, the circulation pump can cause extra power costs of up to 60 euros per month.Also clogging temperature controllers are a major issue.
