The Heatrae Sadia Megaflo 1250 Litre Indirect Unvented Hot Water Cylinder (45050574) is a large-scale, mains-pressure hot water storage cylinder built for the most demanding commercial and high-occupancy applications. Manufactured from duplex stainless steel and rated to a maximum working pressure of 10 bar, it provides a consistent, high-flow hot water supply fed directly from the mains with no cold water storage cistern or header tank required.

The Heatrae Sadia Megaflo Indirect Cylinder (45050574) is an unvented system that delivers balanced mains-pressure hot and cold water throughout the building. Indirect heating is achieved via an internal coil connected to a primary heating circuit - typically a gas boiler, oil boiler, or heat pump. Purpose-built for hotels, hospitals, care homes, leisure centres, large HMOs, and other high-demand commercial premises where an uninterrupted, high-volume hot water supply is essential to daily operations.

Key Benefits

• 1250 Litre Storage Capacity - Provides exceptional hot water storage volume for large commercial buildings and high-occupancy premises, with capacity to serve multiple simultaneous draw-off points without pressure drop.
• 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 efficiently from a connected boiler or heat pump, ensuring broad compatibility with gas, oil, and renewable primary heat sources.
• Unvented System - No Cold Water Tank Required - Operates directly from the mains supply, eliminating the need for a roof-mounted or plant room cistern and significantly reducing the overall system footprint.
• Duplex Stainless Steel Inner Vessel - Duplex stainless steel construction delivers long-term corrosion resistance, an extended service life, and consistent performance across a wide range of water quality conditions.
• High-Performance Thermal Insulation - A CFC-free foam-insulated outer jacket minimises standing heat losses, maintaining stored water temperature and reducing energy consumption between heating cycles.
• Industry-Leading Heat Recovery - High-performance super coils achieve heat recovery times of under 60 minutes across all models, ensuring a continuous and reliable hot water supply even during sustained periods of peak demand.
