Project Overview

For a busy social hub, UL required quiet, efficient heating and reliable DHW without fossil fuels. A fully electric heat-pump plant—sized for peaks but ultra-efficient at part load—now underpins day-to-day operations. 

Scope of Works

• 6 × MasterThermBA60i inverter air-to-water heat pumps
• LTHW radiator circuits for space heating
• High-efficiency DHW generation and storage
• Smart controls integrated to occupancy/usage profiles
• Open protocolModbus/BACnet connectivity to BMS

System Description

• Six BA60i units operate incascade with lead/lag rotation, ensuring optimal COPs across seasons and built-in resilience (N+1 style).
• Multi-zone radiator distribution allows targeted heating across open-plan areas, breakout spaces, and offices.
• PLC logic manages flow temps, pumps, schedules, and DHW control with full BMS visibility.

Project Results & Benefits

• Even temperaturesin high-traffic spaces.
• On-demand DHWduring peaks without impacting heating.
• Operational flexibilityand easy maintenance with modular plant.

Campus leadership in decarbonisation and energy stewardship.
