Preventative Maintenance. Hydraulic Balancing. Systemic Reliability.
A central heating system is a complex hydraulic network that requires more than just a functional boiler to operate effectively. At TaskPigeon, our central heating services are engineered audits designed to optimise the distribution of thermal energy across your entire property. Our elite engineers focus on identifying early signs of component fatigue and hydraulic imbalance, ensuring your system maintains its design efficiency and delivers consistent warmth to every room.
We believe that a professional service should optimise the performance of the entire network, not just the heat source. We apply rigorous diagnostic checks to every radiator, pump, and valve.

We utilise infrared technology to verify heat distribution across all emitters. We identify cold spots caused by air locks or sludge build-up, ensuring a consistent temperature throughout the infrastructure.

We test the operational integrity of your circulating pumps and motorised zone valves. By verifying the electrical and mechanical performance, we prevent mid-winter failures of these critical flow-control components.

We recalibrate the system’s expansion vessel and verify the integrity of the pressure relief valves (PRVs). This prevents the common "pressure-drop" cycles that lead to boiler lockouts and air ingress.

We perform a chemical profile test of your system water. We verify that inhibitor levels are sufficient to prevent internal corrosion and the formation of magnetite, which is the primary cause of pump failure.
We provide expert-level maintenance for complex residential systems that require specialised technical knowledge:
Precision Hydraulic Balancing: We perform a full system balance to ensure the correct flow rate Q reaches every radiator. This eliminates “starved” emitters in distant rooms and reduces the overall energy consumption of the system.
Smart Control Synchronisation: We test and update the communication between your boiler and smart thermostats (Nest, Hive, Tado). We ensure that weather-compensation sensors are correctly calibrated to adjust system output based on external factors.
Unvented Cylinder Safety Checks: For properties with high-pressure hot water storage, we perform mandatory G3 safety checks on the cylinder, testing T&P valves and discharge pipework for absolute safety compliance.
Radiator & Emitter Maintenance: We perform precision bleeding and valve lubrication on all emitters. For high-end designer radiators, we ensure all brackets and aesthetic fittings remain secure and vibration-free.

We run the system to its maximum design temperature to identify circulation delays and cold spots.

We manually trigger zone valves and pumps to verify mechanical response times and electrical integrity.

We test the system water, top up inhibitors, and recalibrate the expansion vessel to its design pressure.

We adjust the lockshield valves on any under-performing radiators to restore total system equilibrium.
Common questions about our elite Heating services.
While the boiler requires an annual check, we recommend a full system service every 12 to 24 months. This ensures that the water chemistry is maintained and that the hydraulic balance hasn't been compromised by air ingress or manual adjustments.
Cold spots at the bottom are usually a sign of "sludge" or magnetite build-up. During a service, we identify these areas and recommend the appropriate remediation, such as a localized flush or the addition of chemical dispersants.
Yes. Our Central Heating Service is a "top-to-bottom" audit that includes a full technical service of your boiler as the primary heat source, ensuring the entire network is synchronized and efficient.
A comprehensive TaskPigeon system audit typically takes between 90 and 120 minutes. This allows our engineers enough time to test every radiator, calibrate the controls, and perform a full combustion analysis on the boiler.
