How to Choose the Right Oil Burner Motor for Your Boiler

If your oil boiler has stopped working or the burner isn't firing up, a faulty oil burner motor could be to blame. Replacing it isn’t always straightforward—especially with so many different models and specifications. At Heating Parts Specialists, we’re here to help you get it right the first time.

Here’s a quick and practical guide to choosing the right burner motor for your boiler.

Why the Right Oil Burner Motor Matters

The burner motor powers the fan and oil pump—if it fails, your boiler won’t ignite, and your heating and hot water will shut down. Choosing the correct motor ensures:

• Safe and efficient operation
• Compatibility with your burner assembly
• Long-lasting, trouble-free performance

Step 1: Identify Your Boiler and Burner

Before you start shopping, collect the following:

• Boiler model (e.g. Worcester Danesmoor 20/25, Grant Vortex Pro 26-35)
• Burner type (e.g. Riello RDB, Ecoflam Minor, Bentone B11, EOGB X Series)
• Motor rating (wattage or horsepower)
• Existing motor label (brand, model no., RPM, capacitor size)

Tip: Take a clear photo of your current motor's data plate and burner unit—it helps us identify the right part for you.

Step 2: Match Motor Specs

When replacing your motor, ensure the key specs match:

• Voltage & Frequency: Usually 230V, 50Hz for UK domestic boilers
• Wattage / HP: Common sizes include 70W, 90W, or 100W
• RPM: Most oil burner motors run at 2800–3000 RPM
• Mounting & Shaft Size: Flange type, shaft diameter, and length must align
• Direction of Rotation: Some motors are clockwise, others anticlockwise
• Capacitor Rating: Usually between 4μF to 6.3μF – always check the existing one
