Position: Senior Mechanical Design Engineer (Renewable Thermal Systems) Location: Bristol/ Hybrid Salary: £65,000 - £80,000 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 1. 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. 2. 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. 3. 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.

Job Title: Project Manager - Heat Pumps Location: Bristol Salary: £75k-£90k You will be delivering large-scale Ground Source (GSHP) and Air Source (ASHP) infrastructure think district heating networks for tower blocks, 2MW+ energy centres for hospitals, and complex industrial retrofits. The Role Reporting to the Construction Director, you will take full ownership of major renewable installations from pre-construction through to commissioning and handover. Project Delivery: Lead the delivery of renewable energy projects ranging from £2m-£10m m, managing the programme, budget, and quality. Technical Leadership: oversee the installation of complex mechanical plant rooms, large-scale heat pumps, and associated district heating pipework. Commercial Control: Manage JCT/NEC contracts, handle variations, and ensure commercial protection throughout the lifecycle of the build. Stakeholder Management: Act as the primary interface for high-profile clients (NHS, Local Authorities, Tier 1 Developers), managing expectations and reporting. Site Logistics: Manage specialist sub-contractors, including drilling teams (for GSHP), heavy lifting/cranage, and civil engineering partners. The Candidate We are looking for doesn't necessarily need to have installed a heat pump before, but you must have a strong Mechanical/M&E background and experience delivering major infrastructure. Experience: Proven track record as a Project Manager on mechanical/infrastructure projects valued at £2m+. Technical: Strong understanding of plant rooms, LTHW systems, chillers, or district heating. Experience with GSHP/ASHP is highly advantageous but not essential if you can demonstrate transferrable engineering competence. Contract Knowledge: Solid understanding of JCT and NEC forms of contract. Mindset: Solutions-focused. These projects are technically complex and often live environments; we need someone who solves problems, not just reports them The Package Basic Salary: £75k - £90k (DOE) Vehicle: Company EV or generous car allowance Bonus: Performance-related project bonuses Pension & Private Health Progression: Clear pathway to Project Director
