Where’s the job?

Overview

• Installing oil-fuelled central heating units requires careful planning, precise installation and adherence to safety standards.

• Skill level: 4 / 5 (knowledge of fuel systems, mechanical fittings and electrical control is essential).

• Typical duration: 1 – 2 days depending on unit complexity and site preparation requirements.

Safety First

• Ensure adequate ventilation as oil combustion produces fumes that must be safely dissipated.

• Handle fuel supplies with extreme caution and store oil as per manufacturer and regulatory guidelines.

• Always wear appropriate personal protective equipment when managing heavy components or fuel.

• Check that all fuel connections are secure and leak‐free before starting the system.

• Follow local regulations regarding the installation, operation and maintenance of oil-fuelled systems.

Tools & Materials

Step-by-Step

1. Site preparation – ensure the area complies with clearance, ventilation and regulatory requirements.

2. Install the fuel storage tank and lay the oil supply lines, checking for secure and leak-free connections.

3. Position the oil-fuelled central heating unit on a stable, level base.

4. Connect the fuel supply and electrical wiring, ensuring all fittings are secure and RCD-protected where necessary.

5. Test the system – check for fuel leaks and ensure the electrical controls operate as intended.

6. Carry out an initial burn-in test to stabilise the heating output and balance the system.

7. Finalise connections and secure the unit, ensuring compliance with all installation standards.

Completion Checks

• The unit operates steadily, delivering uniform heat output and efficient combustion.

• All fuel and electrical connections are leak‐free and secure.

• Control systems respond accurately to thermostat inputs.

• Installation adheres to local safety and emission standards, ensuring warranty validity.

When to Call a Pro Instead

If the installation involves complex fuel supply layouts, intricate ventilation or integration with an existing heating system, it is wise to employ a certified heating engineer or oil burner specialist. This ensures safety, compliance with regulations and full warranty protection.
