The Gledhill StainlessLite Plus Heat Pump 300L Cylinder is a high-quality, unvented stainless steel hot water cylinder specifically designed for use with air source and ground source heat pumps. It delivers mains pressure domestic hot water efficiently by maximizing heat transfer from the lower temperature output typical of heat pump systems.

Key Features

• Capacity: Approximately 300 litres
• Material: Durable duplex stainless steel construction resistant to corrosion
• Heat Exchanger: High-efficiency multi-pass corrugated stainless steel coil designed to maximize 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. 1990 mm, Diameter 550 mm
• Weight: Approx. 46.6 kg empty
• Insulation: Typically fitted with high density, HCFC-free Envirofoam insulation for reduced heat loss
• Included Accessories: Compression fittings, pressure & temperature relief valve, 90° elbow for hot water draw-off, flexible hose for expansion vessel
• ErP Rating: C
• Warranty: 25 years manufacturer guarantee
• Design Notes: Supports legionella risk prevention with immersion heater thermostat controls that activate backup heating below heat pump max temperature and switch off at 60–65°C, minimizing direct electricity use
• Variants: Standard and Slimline version available (Slimline model has reduced diameter around 475 mm for restricted space)

Applications

• Ideal for residential and light commercial hot water systems using air source or ground source heat pumps
• Designed for systems requiring mains pressure domestic hot water with efficient low temperature heat transfer
• Suitable for heat pump systems that may not regularly raise stored water temperature to 60°C
