A structured summary of our engineering and support capabilities, including scope boundaries and standard response parameters.

Service Area Specification
System Design & Sizing Thermal load calculation (EN 12831), equipment selection, BIM-compatible 3D layout, hydraulic schematic development. Covers air-source, water-source, and ground-source configurations up to 2 MW heating capacity per system.
Installation Supervision Factory-trained installation oversight, refrigerant charge verification, electrical connection audit. Standard commissioning protocol: 72-hour monitored startup with COP measurement at 25%, 50%, 75%, and 100% load points.
Preventive Maintenance Compressor oil spectrometry, electronic refrigerant leak detection (EN 378 compliant), heat exchanger thermal imaging, control system calibration. Recommended intervals: quarterly for commercial, semi-annual for residential.
Remote Monitoring IoT-connected performance tracking via cloud platform. Real-time COP, supply/return temperatures, compressor run hours, and defrost cycle frequency. AI-driven anomaly detection with 48-hour advance fault prediction.
Emergency Response 4-hour guaranteed response across 40 service centers. Priority spare parts logistics with 48-hour delivery for standard components. Temporary heating solutions available for critical facilities.
Refrigerant Services R-410A to R-32 conversion, R-290 system servicing (EN 378 certified technicians), F-Gas compliance documentation. Transcritical CO2 cascade servicing for industrial high-temperature applications.
Retrofit & Upgrades Inverter compressor upgrade kits, IoT connectivity modules for legacy systems, low-GWP refrigerant conversion packages. Typical upgrade payback: 18-30 months from energy savings.
Coverage Limitations Borehole drilling and geological surveys require third-party contractors (we coordinate with certified partners). Custom BMS integrations beyond BACnet/Modbus standard profiles billed at project engineering rates. Zone 0 ATEX applications outside current service scope.

Our Engineering Methodology

A four-phase approach that ensures every project moves from requirements analysis to verified performance with full traceability.

01

Requirements Analysis & Site Survey

Our engineers conduct a detailed site assessment covering building thermal envelope data, existing HVAC infrastructure, energy consumption history, and local climate profiles. For ground-source projects, we coordinate thermal response testing (TRT) with certified geotechnical partners. Output: a requirements specification document with defined performance targets, constraints, and risk factors.

02

System Engineering & Equipment Selection

Using thermal simulation software and manufacturer performance data, we model system behavior across the full range of operating conditions. Equipment selection considers not only rated COP but also part-load efficiency (SEER/SCOP), refrigerant type, noise emission at property boundaries, and lifecycle cost including maintenance projections over 15-20 years.

03

Installation Supervision & Commissioning

A StiebelHeat commissioning engineer is present for all critical installation milestones: refrigerant circuit pressure testing, electrical connection verification, BMS point mapping, and the 72-hour monitored startup. We measure actual COP at four load points and compare against design predictions. Any deviation exceeding 8% triggers an engineering review before system handover.

04

Performance Verification & Ongoing Optimization

Post-commissioning, the system is connected to our remote monitoring platform for continuous performance tracking. Seasonal COP is calculated from measured data and compared against EN 14825 rated values. Annual performance reviews identify optimization opportunities: defrost cycle tuning, flow rate adjustments, and control strategy refinements that typically improve real-world COP by 5-12% in the first operating year.
