testo 300+ Flue Gas Analyser Heat Pump Kit
The testo 300+ Heat Pump Kit is a professional flue gas analyser package for engineers working across boilers, hybrid heating systems, and heat pump-related HVAC workflows.How to Support Modern Heating Work Across Boilers and Heat Pumps
When engineers work on both traditional boilers and modern low-carbon heating systems, flexible test equipment becomes essential. The testo 300+ Heat Pump Kit supports combustion testing for gas and oil-fired appliances while fitting into wider heating and HVAC diagnostic workflows.This makes it useful for engineers working on hybrid systems, boiler upgrades, and heat pump installations. It helps professionals stay equipped for current boiler servicing while preparing for the growing demand for renewable heating support.
The kit is suitable for domestic, commercial, and light industrial heating applications.
Why Combustion Testing Still Matters in Hybrid Heating Systems
Even as heat pumps become more common, many sites still use boilers as part of the heating system. Accurate flue gas analysis remains essential for checking appliance safety, efficiency, and emissions.The testo 300+ supports:
- CO and O₂ measurement: Helps assess combustion safety and air supply.
- Flue gas temperature checks: Supports boiler efficiency assessment.
- Draught and pressure support: Helps verify flue and appliance operation.
- Calculated values: CO₂, excess air, and efficiency for clear performance checks.
- Real-world application: On a hybrid heating site, engineers can check boiler combustion and support wider heating diagnostics during the same visit.
Solving Mixed-System Diagnostic Challenges
Modern heating systems can involve boilers, heat pumps, cylinders, controls, and distribution circuits. Faults may come from combustion issues, temperature imbalance, pressure problems, or poor system setup.The testo 300+ Heat Pump Kit helps engineers take a more joined-up approach. It supports boiler combustion checks while connecting naturally with Testo temperature, pressure, and HVAC accessories for wider system analysis.
