20+

Use this HIU service check sheet to commission and service heat interface units in apartments. Record site details, HIU type and serial numbers, heat meter readings (energy, volume, hours, temperatures, delta, flow rate, consumption), operating pressures, bypass and strainers, thermostat settings, expansion vessel charge, leaks, labeling, and valve positions. Verify heating performance in hot water and heating modes, zone valves, pump model and speed, programmer and thermostats, radiator preset valves, and system filling loop removal. Capture hot and cold water temperatures at all outlets and cold water meter details. Leave the unit tested and operational.

MBS QA M 3.1 HIU Commissioning Sheet
This MBS QA M 3.1 HIU Commissioning Sheet helps engineers and QA teams commission heat interface units in apartments or dwellings. Record property and HIU details, serial numbers, and checks for valves, insulation, electrical supply, and strainers. Capture heating mode parameters including design flow and return temperatures, pressures, and eight heat meter readings. Verify secondary heating setup, pump settings, thermostat configuration for multiple zones, valve actuation, inhibitor and flushing certification, and system shutdown behavior. In hot water mode, log HIU thermostat settings, heat meter readings, and tap temperatures and flow rates for each appliance. Include cold water meter readings and engineer sign-off to complete a compliant handover.

Heat Pump and Heating System Inspection
This comprehensive checklist supports facilities and property teams in inspecting heat pumps and related building systems. Review accessibility, airflow, insulation integrity, and signs of refrigerant or electrical issues. Check glycol levels, condensate routing, primary and secondary pumps, Y strainer cleanliness, and ground loop pressure/PRV. Assess DHW cylinder and heating components: expansion vessels, zone valves, relief valves, magnetic filter, sensors, thermostats, and programmer. Record system pressure, hot water temperature, heat curve, flow meter readings, and schedules for heating and hot water. Include legionella controls and verify smoke/heat alarms, control switches, intercoms, and alarm data badges. Capture tenant and engineer names and signatures.

Service and Commissioning Report
This Service and Commissioning Report template helps teams in renewable energy and heating verify safe installation and startup. Capture project details, site, and contact info, then record heat pump make, model, serial, and ID plate. Validate ground loop pressure tests, glycol fill and freeze protection, and manifold integrity. Document primary and secondary heating systems, underfloor heating controls, and heat curves. Log domestic hot water cylinder model, capacity, and legionella protection. Enter key temperatures for outdoor, room, supply, return, hot water, and brine in/out, plus heating and hot water run times and stop temperatures. Confirm compliance with building regulations, electrical supply and isolation, sensor connections, valves and filters, DHW safety devices, and internet connectivity. Track job status, required parts or quotes, corrective actions, and collect on-site representative and auditor signatures.
