Project Overview

Set in the scenic surroundings of Adare Manor, Co. Limerick, this project involved the installation of a versatile and efficient heating solution for a boutique chocolate production facility. The challenge was to deliver both space heating and domestic hot water (DHW) from a single, compact system—without compromising performance or reliability.

Scope of Works

• Installation of: 1 × MasterTherm BA45iP inverter heat pump
• Provide year-round space heating to the production and staff areas
• Supply domestic hot water for staff kitchens, hygiene stations, and cleaning needs
• Operate independently without a separate BMS via MasterTherm’s integrated smart controls

System Description

The BA45iP is a high-efficiency, air-to-water heat pump with an output of up to ~22 kW, well-suited to medium‑demand environments like light industrial or food production. This single unit serves dual functions: (1) LTHW for space heating via radiators and panel heaters; and (2) DHW production for welfare and sanitation requirements. Advanced PLC programming manages temperature and flow distribution across heating and hot-water circuits without external intervention. Monitoring and remote adjustments can be made through the MasterTherm online platform, offering live performance insights and remote diagnostics.

Project Results & Benefits

• Streamlined plantroom design with one unit handling both heating and DHW
• Optimised energy use across both applications, yielding significant operational savings
• Quiet, compact plant well-suited to artisan production environments
• Lower maintenance burden with minimal ancillary equipment and smart automation
• Positive environmental impact with measurable reductions in carbon emissions

Technical Highlights

• DHW priority logic with cylinder temperature sensors ensures rapid reheat and stable draw-off temperatures.
• Thermostatic mixing valves maintain safe outlets (typ. 50–55 °C) while allowing higher cylinder storage setpoints.
• Night setback and optimum-start control minimise energy without compromising morning comfort.
• Inverter compression provides strong part‑load efficiency for shoulder seasons.
• Optional recirculation loop control reduces DHW distribution losses and temperature decay.

Energy & Carbon (SEAI)

Compared with direct‑electric or gas boilers, heat‑pump DHW and LTHW typically reduce input energy by ~50–70% for the same useful heat, translating to lower CO₂ emissions and operating costs.

• Project approach aligns with SEAI guidance on electrification and efficient DHW production.
• Performance metering can support SEAI-aligned reporting and continuous improvement programmes.
