Draper immersion heater wrench 85mm
Product description
If you work on hot water systems or general plumbing maintenance, the right wrench makes tightening and loosening much more straightforward. The Draper immersion heater wrench is designed to fit the immersion heater element correctly, using a matched size for a secure hold. This helps you apply the right effort without struggling with an incorrect tool, which can waste time and damage fasteners in the process. 🔧
Key points
The Draper 13694 Expert immersion heater wrench is a specialist tool for working with immersion heater components. It is built around the correct fitting size, with an 85mm octagonal head that is intended to match the immersion heater wrenching points accurately. That means less faffing around and more time spent getting the job done properly.
This wrench is part of the Draper Expert range, which is positioned around reliable everyday performance for trades and home maintenance. The head uses an octagonal profile, making it easier to engage firmly and maintain control while you turn. If you already know the job calls for an 85mm fitting, this tool can be the practical choice to keep your toolkit aligned with the task.
As with any installation work, it is worth keeping basic safety in mind before removing or fitting heater components. Turn off power where relevant, allow any water to cool, and follow standard workshop or site procedures. Having the right immersion heater wrench to hand can make a noticeable difference to how smoothly the work goes.

What stands out
What you’ll notice most with this wrench is the focus on the correct engagement geometry. The octagonal 85mm form is intended to seat properly, which helps you avoid rounding edges that can happen when the tool does not match the fitting. That secure contact matters most when you are working with fasteners that may be tight or have been in place for a while.
It is also a good example of a tool being built for a defined job rather than being a general-purpose compromise. If you routinely carry out maintenance involving immersion heaters, having the correct size reduces the risk of tool slip and improves efficiency. Worth considering if your work often includes fitting checks, replacement jobs, or responsive repairs where time on site counts.
For storage and daily use, the wrench format is simple and robust, and it fits naturally into a standard spanner or specialist tool collection. If you are building a set for hot water system service, this size makes sense alongside other matching tools you already keep. 🙂
Who it’s for
It’s a good fit if you need an immersion heater wrench and you specifically require the correct 85mm octagonal size. You may want to skip it if your work does not involve immersion heater components or if your tools are sized for a different fitting. It suits plumbers, maintenance technicians, and handy homeowners who prefer to keep the right specialist tools available for common repairs.
Before purchase, double check the required fitting size for your immersion heater setup so you are matching the correct spanner dimensions. Having the right fit is the difference between a smooth job and repeated adjustments that slow everything down. ✅
