Mains Pressure Hot Water Storage Service Report

Use this mains pressure hot water storage system service report to capture customer and site details, cylinder make, model and serial number, engineer and company info, and service date. Record primary circuit type and maximum primary flow temperature, incoming static cold water pressure, strainer cleaning, water hardness and scale reduction, thermostat setpoint, maximum hot water flow rate, solar compatibility, nearest outlet temperature, and pipe insulation. For unvented systems, log location and setting of the pressure reducing valve, test temperature and pressure relief and expansion valves, verify tundish and discharge pipework comply with Part G, confirm energy source cut-out devices, and check expansion vessel or air gap. For thermal stores, note achievable store and maximum hot water temperatures. Confirm compliance with Building Regulations and manufacturer instructions, demonstrate controls to the customer, and capture engineer comments, parts used, and signatures.
