We are looking for a specialist Mechanical Design Engineer to lead the transition from fossil fuel combustion to Large-Scale Heat Pump Technology. You will be responsible for the 'physics' of the system—ensuring that high-capacity heat pumps are integrated into hydronic circuits that actually deliver on their efficiency promises.
Core Technology Focus
- Air Source Heat Pumps (ASHP)
- Cascade Systems: Designing multi-unit ASHP arrays for commercial peak loads.
- Defrost & Ambient Logic: Managing acoustic mitigation, airflow requirements, and defrost cycle impacts on system continuity.
- Bivalent Integration: Designing systems that integrate ASHPs with existing LTHW or backup heat sources.
- Ground Source Heat Pumps (GSHP)
- Array Design: Coordinating borehole heat exchangers (BHE), horizontal loops, and thermal conductivity testing.
- Ambient Loops: Designing 5th Generation heat networks and 'sharing' energy across multi-user sites.
- Passive Cooling: Leveraging ground temperatures for high-efficiency cooling integration.
- Hydronic Architecture (The 'Engine Room')
- Low-Temperature Hot Water (LTHW): Designing for Heat Pump efficiency (e.g., 45°C flow / 35°C return).
- Buffer & Separation: Precise sizing of buffer vessels and Low-Loss Headers to prevent short-cycling and maintain hydraulic separation.
- System Balancing: Specifying PICVs and variable-speed pumping to ensure optimal mass flow rates.
Key Professional Duties
- Detailed Modeling: Using IESVE or Hevacomp to ensure heat loss calculations meet BS EN 12831 standards.
- BIM Coordination: Utilizing Revit MEP for 3D spatial coordination of complex plant rooms.
- Technical Compliance: Ensuring all designs meet CIBSE CP1 (Heat Networks) and MIS 3005 (MCS) standards.
Candidate Profile
- Technical Background: Degree-qualified (BEng/MEng) with a deep understanding of thermodynamics.
- Professional Status: CEng or MCIBSE preferred.
- Experience: You must have a proven track record of designing ASHP or GSHP systems —not just supervising them, but performing the actual hydronic and thermal calculations.
