ACCA Introduces Professional Solutions for Limescale, Sludge and Corrosion Problems in Heating Systems
ACCA S.p.A., an Italian company specializing in industrial chemicals and water treatment technologies, has shared its technical insights and recommendations for addressing limescale deposits, sludge accumulation, corrosion and circulation problems in heating systems.
In its recently published technical article, ACCA emphasizes that abnormal noises in boilers and closed-loop heating systems are not necessarily caused by limescale alone. Mechanical problems, trapped air and inadequate water circulation can produce similar symptoms.
Causes of Noise and Performance Problems in Heating Systems
Over time, mineral deposits, corrosion products and suspended particles can negatively affect water circulation in heating systems.
Deposits accumulating in heat exchangers, pumps, filters and control valves may restrict water flow and reduce heat transfer efficiency.
These conditions can contribute to increased energy consumption, reduced system performance and premature wear of equipment.
ACCA recommends carefully evaluating the symptoms before selecting a treatment method. For example:
-
Whistling or kettle-like noises may be associated with restricted circulation or limescale deposits.
-
Gurgling sounds may indicate trapped air or pressure-related problems.
-
Persistent humming and vibrations may originate from pumps or other mechanical components.
-
Reduced circulation and uneven heating may indicate sludge accumulation or hydraulic balancing problems.
Identifying the actual cause is essential before proceeding with chemical cleaning.
Cleaning and Protection with ACCA TERMO HD Products
ACCA offers professional maintenance and water treatment solutions through its TERMO HD product range, developed to address different conditions in heating circuits.
TERMO HD 1002 – Scale Control and Noise Reduction
TERMO HD 1002 contains dispersing and anti-scaling agents designed to help manage limescale-related problems in heating systems. Its action on existing deposits is gradual and may require several days or weeks, depending on the characteristics of the deposits.
TERMO HD 1004 – Cleaning Existing Heating Systems
Designed for heating systems that have been in operation for an extended period, TERMO HD 1004 helps remove sludge, corrosion residues and organic or inorganic deposits. Proper cleaning can support improved water circulation and heat transfer.
TERMO HD 1008 – Intensive Cleaning for Heavily Contaminated Systems
TERMO HD 1008 is a professional, non-acidic cleaning product developed for heating systems affected by substantial deposits and restrictions. It can be used with suitable professional cleaning equipment according to the requirements of the installation.
TERMO HD 1001 – Corrosion Protection
TERMO HD 1001 contains corrosion inhibitors and anti-scaling dispersing agents designed to protect heating circuits. It can be considered as part of a long-term water conditioning programme following appropriate system cleaning and rinsing.
The Importance of Accurate Diagnosis and Water Quality Monitoring
ACCA emphasizes that not every noise or circulation problem can be solved through chemical treatment.
An effective maintenance programme should evaluate water pH, conductivity, hardness, deposit characteristics and the materials used in the heating circuit.
Following cleaning, proper rinsing, water conditioning and corrosion protection are important for maintaining long-term system performance.
Water Treatment and Maintenance in Industrial Facilities
Maintaining suitable water quality in heating and heat-transfer systems is essential for reliable operation and energy efficiency.
ACCA's professional chemical solutions are designed to support system cleaning, deposit control and equipment protection when applied under suitable operating conditions.
Product selection and treatment procedures should always be based on system characteristics, equipment manufacturer requirements and the actual condition of the installation.
