✔ Double Wound Coil Design — Maximum Heat Exchange — The double winding coil configuration delivers high thermal exchange efficiency with low flow resistance, ensuring rapid, consistent heat transfer from the primary circuit to the domestic hot water supply.

✔ Blue Glass 4753 Glass-Lined Steel Tank — WRAS Certified — The steel tank interior is glass-lined using the Blue Glass 4753 flow-coating process at 850°C, providing exceptional corrosion resistance and long-term water quality protection. WRAS (BS6920-1) certified for compliance with UK water regulations.

✔ Optimised High-Performance Coil — Limescale Reduction by Design — The HIGH performance coil features lowered loops specifically engineered to optimise heat exchange efficiency while actively reducing limescale production.

✔ Dual Magnesium Anodes — Continuous Corrosion Protection — Two corrosion-proof magnesium anodes provide comprehensive cathodic protection throughout the tank interior, safeguarding against electrochemical corrosion and extending cylinder service life.

✔ Low Pressure Loss — Reduced Circulation Energy Consumption — Engineered for minimal pressure drop across the heating fluid circuit, reducing the energy demand on circulation pumps and delivering meaningful operational cost savings across the life of the installation.

✔ High-Density Polyurethane Foam Insulation — Exceptional Thermal Retention — Very thick, high-density PU foam insulation with a Lambda value of 0.022 W/mK minimises standing heat losses, maintaining stored water temperature efficiently and reducing system energy consumption.

✔ Heat Pump Optimised — Engineered for Low-Temperature Primary Circuits — Specifically designed to maximise performance when connected to air source or ground source heat pumps, extracting maximum useful heat from low-flow-temperature primary circuits efficiently and consistently.

✔ Flexible System Integration — Central Heating and Beyond — Suitable for connection to central heating systems and compatible with a wide range of further system integration options, including single and three-phase electric immersion heating elements via available integration kits.

✔ Frontal Inspection Access — Series-Specific Configurations — Inspection hatch configurations are sized and positioned appropriately across the range — from a single 134mm hatch on the 300–600 series to dual hatches on the 800–1000 series and a 280mm hatch on the 1500 series.
