This forward-thinking investment significantly reduces our carbon footprint while enhancing guest comfort, energy reliability, and operational efficiency across the hotel.

Scope of Works

• A range of heating zones were upgraded across the hotel complex, including:
• Main hotel heating system powered by modular air-to-water heat pumps
• Domestic hot water (DHW) supply using high-temperature heat pumps
• Leisure Centre and Pool Hall, including humidity and air temperature control
• Conference and function rooms, upgraded with dedicated heat pump and AHU systems
• Lobby and public zones, upgraded with underfloor heating and inverter-driven heat pumps
• Smart control integration with zone-by-zone optimization and BMS compatibility

Heat Pump System Overview

The hotel’s heating system now consists of high-performance MasterTherm air-to-water heat pumps, specifically chosen and zoned to match the unique demands of each area.

Main Hotel Heating

• 6 × MasterTherm BA60i Inverter Heat Pumps
• Supply efficient LTHW to the central hotel zones
• Inverter technology dynamically adjusts output to match demand
• Reduces energy consumption, increases equipment longevity
• Domestic Hot Water (DHW)
• 2 × MasterTherm AQ75ZHX High-Temperature Heat Pumps
• Delivers hot water up to 82°C for guest rooms,leisure centre,  kitchens, and services
• Designed to handle peak demand periods with consistent performance

Leisure Centre & Pool Hall

• 2 × BA60is Heat Pumps with Desuperheaters
• Efficient system to heat swimming pool , DHW for showers and AHU
• 1 × Dantherm Air Handling Unit (AHU)
• Manages humidity and air temperature in the pool hall
• Works in tandem with the heat pumps for optimal climate control

Function Rooms & Event Spaces

• 1 × BA60i + 1 × Atrea Roto Duplex 12000 AHU
• Dedicated system serving the Killanuire Conference Room
• 2 × BA60i + 2 × Atrea Roto 12000 AHUs
• Responsive heating and ventilation for additional function rooms

Hotel Lobby & Entrance Area

• 1 × BA45i Inverter Heat Pump
• Serves the underfloor heating system in the hotel’s main lobby
• Provides gentle, even warmth for guest comfort
• Intelligent Control & Monitoring
• All heat pump systems are connected to a centralized smart control system offering:
• Real-time energy monitoring and load balancing
• Weather-compensated setpoint control
• Remote diagnostics and system alerts
• Fully controlled by MasterTherm software Carel PLC no further  Building Management System (BMS) is required.

Project Results & Benefits

This project delivers measurable improvements across energy performance, comfort, and sustainability.

• Energy Efficiency
• Significant reduction in overall heating energy consumption
• Advanced inverter technology ensures systems only use energy when needed
• Environmental Impact
• Lower CO₂ emissions by replacing gas/oil boilers with heat pumps

Tech Notes & Smart Control

• Inverter cascades (BA60i) track varying occupancy; Atrea/Dantherm AHUs reclaim heat and manage pool‑hall humidity.
• High‑temp AQ75ZHX units lift DHW to service kitchens and peak guest draw; weekly anti‑legionella scheduling embedded.
• Lobby UFH operates at low LTHW (e.g., 35/30 °C) for comfort and efficiency.
• Open‑protocol integration available; trend logs support continuous tuning with hotel ops.

Guest Experience & Operations

• Faster recovery after ballroom/functions; stable hot water at peak check‑in/check‑out windows.

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.
