Joule Cyclone Platinum 170 Litre Twin Solar Indirect Unvented Cylinder (TCEMVS-0170LFB)

The Joule Cyclone Platinum 170 Litre Twin Solar Indirect Unvented Cylinder (TCEMVS-0170LFB) is a high-capacity hot water storage cylinder designed for solar thermal and indirect heating systems. Built for reliable, efficient domestic and light-commercial use, it stores and delivers large volumes of hot water while integrating with solar coils and auxiliary heat sources. Durable stainless-steel construction, effective insulation, and twin coil design help maximise heat transfer and minimise energy loss for consistent hot water supply. Key Features 170 litre actual capacity (120 L usable rating listed elsewhere) for ample hot water storage Twin 316L stainless-steel coils (each 16 kW, 0.58 m²) for efficient solar and primary heat exchange LDX 2101 stainless-steel inner cylinder for corrosion resistance and longevity Coated mild steel outer casing with dense PU foam insulation for thermal protection and durability Supports an immersion heater (3 kW @ 230 V) and single immersion port provided High operating limits: max mains pressure 10 bar, operating pressure 7 bar; coil max primary pressure 3.5 bar Low standing heat loss: 1.39 kWh/24h (tested to BS EN 12897:2016) Weight: 49 kg empty, 219 kg full — robust build for fixed installations Warranty: 1 year Ideal Use Cases Residential homes requiring substantial stored hot water (morning/evening peak demand) Properties using solar thermal panels as a primary or supplementary heat source Light commercial installations where indirect unvented cylinders are appropriate Heating systems that need dual coil flexibility (e.g., solar + boiler) Renovation or new-build projects seeking durable stainless-steel cylinders for modern interiors Product Specifications Specification Value Model TCEMVS-0170LFB Brand CYCLONE Product Group Code SOLAR Item Category Code Stainless ERP Type IndirectUnvented Actual capacity (Ltr) 170 Capacity (listed) 120 L Cylinder material LDX 2101 (stainless steel) Outer casing Coated mild steel Thermal insulation Dense PU foam Foam thickness 0 Unit weight empty (kg) 49 Unit weight full (kg) 219 Number of immersions 1 Immersion spec 3 kW @ 230 V No. heat exchangers 2 Coil material 316L stainless steel Coil 1 rating (kW) 16 Coil 2 rating (kW) 16 Coil 1 surface area (m²) 0.58 Coil 2 surface area (m²) 0.58 Coil 1 max primary pressure (Bar) 3.5 Coil 2 max primary pressure (Bar) 3.5 Coil 1 resistance (Bar) 0.05 Max mains water pressure (Bar) 10 Operating pressure (Bar) 7 Operating temperature (°C) 60 Safety valve temperature (°C) 90 Heat loss (kWh/24h) 1.39 Tested to standard BS EN 12897:2016 Warranty terms (Year) 1Y
