Applications

• Installing and removing 85mm immersion heater elements in hot water cylinders

• Boiler and cylinder maintenance where immersion elements need servicing or replacement

• Plumbing repair and service work in domestic and light commercial systems

• Working in tight or awkward spaces where a straight spanner is difficult to use

• Any suitable 85mm hex fitting where a cranked immersion spanner is appropriate

How to Use

• Isolate the power supply and allow the cylinder and immersion heater to cool fully before starting work.

• Ensure the immersion heater nut is accessible, then position the 85mm hex opening of the spanner securely over the nut.

• Use the cranked handle to apply steady, controlled torque to loosen or tighten the element, working from the side where space is limited.

• For very stubborn fittings, additional controlled force can be applied by gently tapping the spanner with a hammer, taking care not to damage the nut or cylinder.

• Once the element is removed or installed, re-check tightness by hand and complete any sealing and recommissioning in line with manufacturer guidance.

• After use, wipe the spanner clean and store it in a dry place to help maintain the corrosion-resistant finish.

Dickie Dyer 85mm Cranked Immersion Heater Spanner – Key FAQs

• What size immersion heater element does this spanner fit?
  It is designed to fit the standard 85mm immersion heater elements commonly used in UK domestic hot water cylinders and similar installations.

• Is the cranked design helpful in tight spaces?
  Yes, the cranked handle allows you to work from the side of the cylinder, giving better leverage and access where space is limited or obstructed.

• Can I use this immersion spanner with a power or impact tool?
  No. It is designed for manual use only. Do not use with impact drivers or power wrenches, as this may damage both the tool and the heater fitting.

• What is the spanner made from?
  The spanner is forged from a single piece of heavy-duty steel and finished with a corrosion-resistant coating for long service life.

• Will this tool damage the immersion heater nut?
  Used correctly with a snug fit and steady pressure, it provides a firm grip with minimal risk of rounding or damaging the nut. Avoid excessive force or sudden impacts.

• Can I tap it with a hammer to free a stuck element?
  If an element is very tight, gentle, controlled tapping with a hammer on the spanner handle can help to break the seal, but always take care not to over-strike or damage the fitting or cylinder.
