The Heatrae Sadia Megaflo 1000 Litre Indirect Unvented Hot Water Cylinder (45050573) is a high-volume, mains-pressure hot water storage cylinder engineered for large-scale commercial and high-occupancy installations. Constructed from duplex stainless steel and rated to 10 bar working pressure, it delivers a consistent, high-flow hot water supply directly from the mains with no cold water storage tank or header tank required.

Heated indirectly via an internal coil connected to a primary heating circuit, typically a gas boiler or heat pump, the Megaflo 1000 Litre (45050573) operates as a fully unvented system, providing balanced mains-pressure hot and cold water throughout the building. Suited to hotels, care homes, leisure centres, large HMOs, and other high-demand commercial premises where a dependable, continuous hot water supply is critical.

Key Benefits

• 1000 Litre Storage Capacity - Supports sustained high-volume hot water demand across large commercial buildings and high-occupancy premises, with capacity for multiple simultaneous draw-off points.
• Mains Pressure Performance (Up to 10 Bar) - Delivers full mains-pressure hot water to multiple outlets at once, eliminating the need for a cold water storage cistern or header tank.
• Indirect Heating -  An internal coil transfers heat from a connected boiler or heat pump, making the cylinder compatible with gas, oil, and renewable primary heat sources.
• Unvented System - No Cold Water Tank Required - Operates directly from the mains supply, removing the requirement for a roof-mounted or plant room cistern and reducing the overall system footprint.
• Duplex Stainless Steel Inner Vessel - The duplex stainless steel construction provides long-term corrosion resistance, an extended service life, and reliable performance across a wide range of water quality conditions.
• High-Performance Thermal Insulation - A CFC-free foam-insulated jacket minimises standing heat losses, helping to maintain stored water temperature and reduce energy consumption.
• Industry-Leading Heat Recovery - High-performance super coils deliver heat recovery times of under 60 minutes across all models, maintaining a continuous and reliable hot water supply even during periods of peak demand.
