When we first arrived at the property, we were met with a surprising revelation: the tenant was completely unaware that they had a ducted heater. This discovery highlighted a common oversight that can occur in the transition between previous occupants and new tenants.

Upon learning about the existence of the ducted heater, the tenant expressed genuine excitement at the prospect of having central heating in their home. This anticipation for enhanced comfort and warmth set a positive tone for our assessment and repair process.

During our initial assessment, several issues with the heater came to light:

Heater Thermostat with No Power:

We discovered that the heater thermostat had no power, which was traced back to corroded batteries. This common issue can prevent the thermostat from functioning properly and controlling the heating system.

These findings highlighted the importance of thorough diagnostics and troubleshooting to identify and address multiple issues impacting the heater’s functionality.

Tests Performed by Gas Plumbers for Ducted Heaters

Before performing any work, our team went in and conducted some tests that would ensure that we covered all the bases and that the servicing of the ducted heater would go smoothly:

Thermostat Functionality Test:

Tested the thermostat’s functionality after replacing corroded batteries to ensure proper power supply and communication with the heating system.

Thermostat Wires Connectivity Test:

Conducted tests to ensure proper connectivity of thermostat wires after reconnecting them, verifying that signals were being transmitted correctly between the thermostat and the heater.

Ignition System Test:

Tested the ignition system to diagnose the issue of the pilot lighting but the main burner not igniting. Identified and resolved issues such as a faulty igniter or gas flow irregularities.

Safety Lockout Reset Test:

Waited for the heater’s lockout mode to reset after addressing the initial malfunction, ensuring that the system returned to normal operation without safety issues.

Flame Sensor and Pilot Tube Inspection:

Inspected and cleaned the flame sensor and pilot tube to ensure proper functioning and reliable ignition of the main burner.

Burner Pressure Adjustment and CO Testing:

Adjusted the burner pressure to the correct specifications to ensure optimal performance and safety. Conducted CO testing to verify that combustion was efficient and within safe limits.

Overheat Safety Test:

Triggered the overheat safety feature deliberately to ensure that it functioned correctly and that the system responded appropriately without further lockouts or safety hasards.

These comprehensive tests and inspections were crucial in diagnosing the heater’s issues accurately, resolving them effectively, and ensuring that the heating system operated safely and efficiently.

Parts Needed for a Working Ducted Heater

While we didn’t need to replace all of the parts of the tenant’s ducted heater, we’d like to highlight the parts that we usually procure to ensure that the ducted heater repair and service process goes smoothly.

Batteries for Thermostat: Replacement batteries for the thermostat to restore power and enable proper control of the heating system.

Thermostat Wires: If damaged or disconnected, replacement or reconnection of thermostat wires to ensure proper communication between the thermostat and the heater.

Flame Sensor/Igniter: A functional flame sensor and igniter are essential for ignition and proper functioning of the main burner. Cleaning or replacement may be necessary if these components are faulty or dirty.

Pilot Tube: Inspection and cleaning of the pilot tube to ensure a reliable and consistent pilot light, which is crucial for ignition and safe operation.

Isolation Valve and Regulator: Replacement or adjustment of the isolation valve and regulator to control gas flow and pressure, ensuring safe and efficient combustion.

Safety Features Components: Parts related to safety features such as overheat sensors, limit switches, and safety lockout mechanisms, ensuring the heater operates safely and responds to potential hasards.

CO Detector: Installation or testing of a CO detector to monitor carbon monoxide levels and ensure the combustion process is safe and free from leaks.

Burner Pressure Gauge: Equipment to measure and adjust burner pressure to manufacturer specifications for optimal performance and efficiency.

Documentation and Manuals: Ensure the availability of warranties, manuals, and documentation for installed parts and the overall heating system, providing reference and guidance for maintenance and troubleshooting.
