Electric/ Resistance/ Immersion Heater Applications with HydroFLOW®
HydroFLOW® enhances the efficiency of electric resistance or immersion heaters by treating limescale, biofilm, and corrosion, improving heat transfer, and reducing maintenance requirements. It ensures optimal performance, extends equipment lifespan, and minimises energy consumption across various industries.
Optimising Electric Resistance or Immersion Heaters with HydroFLOW®
Electric resistance or immersion heaters are widely used in industrial, commercial, and domestic applications for heating water and process fluids. However, they are highly prone to limescale buildup, fouling, and corrosion, which significantly reduce heat transfer efficiency and increase operational costs.
HydroFLOW® provides an advanced, chemical-free solution to treat limescale and biofouling in electric heating elements. By ensuring clean heating surfaces and improving water quality, HydroFLOW® helps maintain consistent performance, reduces energy consumption, and extends equipment longevity.

HydroFLOW® Solutions for Electric, Resistance & Immersion Heaters: Scaling Control, System Protection, and Extended Life

Treats Limescale & Scale Deposits
Limescale buildup on heating elements acts as an insulator, reducing heat transfer efficiency and increasing energy consumption. HydroFLOW® treats scale formation by keeping minerals in suspension, ensuring optimal heating performance and energy efficiency.
Treats scaling on heating elements and immersion coils
Maintains high heat transfer efficiency
Reduces the need for frequent descaling and chemical treatments
Lowers energy consumption and operational costs
Minimises Biofilm & Bacterial Growth
Heaters operating in water-based systems can develop biofilm, which not only reduces efficiency but also poses hygiene risks, particularly in water heating applications. HydroFLOW® inhibits biofilm formation, maintaining cleaner heating elements and reducing bacterial contamination.
Reduces biofilm accumulation on heating elements and system surfaces
Minimises bacterial growth, improving water hygiene
Enhances overall system cleanliness and efficiency
Lowers the need for chemical biocides


Reduces Internal Corrosion & Protects Heating Elements
Corrosion caused by water quality issues and mineral deposits can lead to premature heater failure, increasing maintenance costs and system downtime. HydroFLOW® mitigates corrosion by reducing fouling and minimising conditions that accelerate metal degradation.
Minimises corrosion of electric heating elements and immersion coils
Extends the operational lifespan of heating components
Reduces the need for anti-corrosion chemical treatments
Improves long-term system reliability
Improves Heat Transfer & Energy Efficiency
When heating elements become coated with limescale and biofilm, they require more energy to maintain performance, driving up operational costs. HydroFLOW® ensures clean heating surfaces, optimising energy efficiency and reducing power consumption.
Maintains optimal heat transfer with minimal energy use
Treats fouling that forces systems to work harder
Lowers operational costs by improving efficiency
Supports sustainable, chemical-free heating system operation


Minimises Downtime & Maintenance Costs
Electric, resistance, and immersion heaters require regular maintenance to remove fouling and scale, leading to costly system downtime. HydroFLOW® reduces maintenance needs by treating common heating system issues, allowing for more efficient and cost-effective operations.
Decreases the frequency of mechanical cleaning and chemical treatments
Reduces costly shutdowns for maintenance and repairs
Ensures continuous, trouble-free operation
Lowers overall lifecycle costs of heating systems
