Rosslare Harbour

Project Overview

As part of a new development at Rosslare Harbour, MasterTherm partnered with Phoenix Mechanical to deliver a high-efficiency heating and hot water solution for a series of new office and welfare buildings. Central to this installation was the design and commissioning of an onsite plant room that supports both space heating and domestic hot water, tailored to meet the needs of this coastal facility.

Scope of Works

  • Installation of 1 × MasterTherm BA60iP inverter-driven heat pump
  • The unit delivers LTHW (Low Temperature Hot Water) to 5 independent heating zones within the welfare building
  • Simultaneous supply of DHW (Domestic Hot Water) for on-site facilities
  • Full control of plantroom operations—including all valves, actuators, and temperature control—managed by MasterTherm’s onboard PLC, eliminating the need for a separate BMS system

System Description

The BA60iP unit acts as the core energy plant for the building, delivering reliable and efficient thermal output year-round. Integrated PLC control provides autonomous system operation with real-time adjustments based on usage and demand. Simplified installation and reduced wiring complexity due to built-in control architecture.

Project Results & Benefits

  • Independent and intelligent control: The self-sufficient control system eliminated the need for a costly BMS, streamlining both installation and future maintenance
  • Operational cost savings: Reduced equipment requirements and simplified system management led to lower setup and running costs
  • Strong system reliability: Real-time monitoring via MasterTherm’s online platform ensures proactive performance management and system resilience
  • Environmental impact minimized: The all-electric system supports a move away from fossil fuels, aligning with sustainability targets and reducing on-site emissions
  • Optimized for remote locations: The compact and autonomous nature of the system made it ideal for deployment in a transport hub environment like Rosslare Harbour

Technical Highlights

  • LTHW design temperatures typically 45/35–50/40 °C for high seasonal efficiency with radiators.
  • DHW priority control with weekly anti-legionella pasteurisation (≥60–65 °C) to ensure hygiene compliance.
  • Zoning via motorised valves and room stats; weather compensation and night setback reduce wasted energy.
  • Optional Modbus to site BMS if required later.
  • Buffer vessel (where used) and VFD pumps maintain stable flow and ΔT across five zones.

Energy & Carbon (SEAI)

Electrification removes on‑site combustion (Scope 1), while inverter modulation lowers electricity use per unit of heat. CO₂ per kWh of delivered heat declines further as the Irish grid continues to decarbonise.

  • Aligned with SEAI public‑sector energy and carbon‑reduction objectives for buildings.
