FlowCyl 300L Unvented High Quality Stainless Steel Heat Pump Cylinder
300L Unvented High Quality Stainless Steel Heat Pump Cylinder
The 300L Unvented High Quality Stainless Steel Heat Pump Cylinder is a robust and efficient hot water storage solution specifically designed for air source and ground source heat pumps. Made from high-grade stainless steel, it provides mains pressure domestic hot water with excellent corrosion resistance and long service life. This cylinder maximizes heat transfer from the heat pump’s lower temperature output, ensuring reliable, energy-efficient performance.
Key Features
- Capacity: 300 litres
- Material: High-grade stainless steel for durability and corrosion resistance
- Heat Exchanger: Multi-pass corrugated stainless steel coil designed to optimize heat transfer from heat pump flow temperatures around 50–60°C while minimizing pressure loss
- Immersion Heater: 3 kW Incoloy immersion heater with thermostat pocket for emergency or backup heating
- Dimensions: Height approx. 1924 mm, Diameter 545 mm
- Weight: Approx. 50 kg empty, 330 kg full
- Coil Surface Area: 2.97 m²
- Standing Heat Loss: Approximately 2.26 kWh per 24 hours
- Insulation: Factory fitted insulation for reduced heat loss
- Warranty: 25 years manufacturer-backed guarantee
Applications
- Designed for heat pump systems requiring efficient mains pressure domestic hot water
- Suitable for residential and light commercial installations
- Optimized for heat pumps that operate at lower flow temperatures to maximize energy savings
