The Heatrae Sadia Hotflo 15 Litre Instant Water Heater is an ideal solution for homeowners and facility managers seeking a reliable, compact hot water supply for kitchens, utility rooms, or bathrooms. By providing mains-pressure hot water directly at the point of use, it significantly reduces wait times and improves daily convenience. While its space-saving design is perfect for under-sink or cupboard installation, users should be aware that the 15-litre capacity is best suited for low-to-medium demand applications rather than supporting multiple high-flow shower points simultaneously.

Installation must be performed by a qualified professional due to the requirements of working with unvented pressure systems. The unit is designed for wall-mounted installation, typically inside a cabinet to keep the plumbing hidden yet accessible. Regular maintenance involves checking the pressure relief valve and ensuring the inlet screen remains clear of debris. Because it is an unvented system, ensure that the expansion vessel and safety valves are inspected annually to comply with safety regulations and maintain optimal efficiency.
