Heatrae Sadia Hotflo Unvented Water Heaters  

Hotflo provides local stored hot water without requiring a separate cold water cistern, giving buyers flexibility when planning washroom facilities. Its heavy-gauge copper inner container incorporates a rod-type heating element sheathed in corrosion-resistant alloy. An externally adjustable thermostat offers settings from 10°C to 70°C, while expanded polystyrene insulation helps reduce stored-water heat loss. Both listed heaters have a 6-bar working pressure, with the range manufactured in the UK and described as KIWA approved to UK Water Supply Regulations. Associated pressure-control, expansion and thermostatic blending accessories are listed alongside the heaters, simplifying project-specific sourcing.
