Scope of Works

• 3 × MasterTherm BA60i inverter heat pumps serving the indoor swimming pool and its dedicated Air Handling Unit (AHU)
• 1 × MasterTherm BA60i supplying domestic hot water (DHW) and space heating for the spa and wellness areas

The System was Designed to:

• Maintain precise temperature control in the pool and surrounding areas
• Deliver continuous DHW supply for showers, changing rooms, and spa treatment areas
• Integrate seamlessly into the facility’s energy management system using advanced onboard MasterTherm PLC controls

System Description

• The BA60i heat pumps are designed for high-demand applications, offering modulating performance for both space and pool water heating
• The poolside AHU benefits from a steady supply of LTHW from the twin BA60i units, ensuring stable temperature and humidity control
• The DHW and spa heating system is powered by a dedicated BA60i, supporting elevated comfort levels required for therapeutic and wellness functions
• Each unit features intelligent onboard control logic, capable of managing heating circuits, valves, and temperature setpoints independently—without requiring a full BMS

Project Results & Benefits

• Tailored comfort delivery: The system was custom-engineered to meet the specific thermal demands of leisure and wellness zones, ensuring guest satisfaction at all times
• Operational resilience: The system provides dependable performance even during peak usage periods, ensuring uninterrupted service in mission-critical areas like pools and spas
• Reduced energy load: By leveraging high-efficiency inverter-driven heat pumps, the facility has significantly lowered its energy consumption compared to legacy systems
• Smart control, simplified management: Advanced PLC functionality allows real-time monitoring and adjustment, empowering facility staff to maintain ideal conditions with minimal input
• Environmental stewardship: The move away from fossil fuels supports the hotel’s broader sustainability objectives, improving its green credentials and lowering its carbon footprint

Tech Notes & Smart Control

• Pool AHU supplied by dedicated BA60i pair for humidity/temperature stability; separate BA60i covers spa/DHW.
• PLC logic supervises valve groups, recirculation loops and optimum‑start for morning ramp‑up.

Guest Experience & Operations

• Spa comfort maintained even during pool peaks; quieter plant enhances wellness areas.

Energy & Carbon (SEAI)

• Switching from fossil-fired plant to high-efficiency heat pumps reduces on‑site combustion (Scope 1) and cuts overall CO₂ per guest‑night.
• Heat recovery (where fitted) further lowers electrical input per kWh of useful heat or DHW.
• Aligned with SEAI guidance for decarbonising hospitality; suitable for EXEED‑style M&V and public‑sector style reporting where applicable.
• Benefits grow as the Irish electricity grid continues to decarbonise, improving the carbon intensity of delivered heat over time.
