Joule Cyclone Platinum 300 Litre Twin Solar Short Indirect Unvented Cylinder (TCEMVS-0300NFC)

The Joule Cyclone Platinum 300 Litre Twin Solar Short Indirect Unvented Cylinder (TCEMVS-0300NFC) is a high-capacity hot water storage cylinder designed for solar thermal and auxiliary heating systems. It provides large-volume, reliable domestic or light‑commercial hot water delivery while maximising heat transfer from solar collectors and backup heat sources. Stainless‑steel construction, twin high‑output coils and dense PU insulation reduce corrosion and standby losses for efficient, long‑lasting performance. Key Features Actual capacity 290 litres for substantial hot water storage Twin 316L stainless‑steel coils (18 kW + 22 kW; 0.67 m² each) for efficient solar and primary heat exchange LDX 2101 stainless‑steel inner cylinder for corrosion resistance and durability Coated mild steel outer casing with dense PU foam insulation to minimise heat loss Single immersion heater port compatible with 3 kW @ 230 V immersion High pressure capability: max mains 10 bar; operating pressure 7 bar; coil primary max 3.5 bar Low standing heat loss: 2.30 kWh/24h (tested to BS EN 12897:2016) Robust build: 67 kg empty, 364 kg full 1 year warranty Ideal Use Cases Large family homes or properties with high hot‑water demand Solar thermal systems paired with a boiler or secondary heat source Light commercial installations requiring significant stored hot water New‑build or renovation projects seeking durable stainless‑steel cylinders Systems needing dual coil flexibility (solar + backup heating) Product Specifications Specification Value Model TCEMVS-0300NFC Brand CYCLONE Product Group Code SOLAR Item Category Code Stainless ERP Type IndirectUnvented Actual capacity (Ltr) 290 Capacity (listed) 300 L Cylinder material LDX 2101 (stainless steel) Outer casing Coated mild steel Thermal insulation Dense PU foam Foam thickness 0 Unit weight empty (kg) 67 Unit weight full (kg) 364 Number of immersions 1 Immersion spec 3 kW @ 230 V No. heat exchangers 2 Coil material 316L stainless steel Coil 1 rating (kW) 18 Coil 2 rating (kW) 22 Coil 1 surface area (m²) 0.67 Coil 2 surface area (m²) 0.67 Coil 1 max primary pressure (Bar) 3.5 Coil 2 max primary pressure (Bar) 3.5 Coil 1 resistance (Bar) 0.06 Max mains water pressure (Bar) 10 Operating pressure (Bar) 7 Operating temperature (°C) 60 Safety valve temperature (°C) 90 Heat loss (kWh/24h) 2.30 Tested to standard BS EN 12897:2016 Warranty terms (Year) 1Y
