Our high quality guaranteed Heating Elements are fully UK manufactured, to exactingly high standards, from high quality component parts (resistance coil wire, magnesium oxide, tubing & electrical connections) then assembled by highly skilled technicians & top CNC machinery.
Our elements can be formed into a variety of shapes to suit your application.
The more “Wiggle Room” you have in terms of power rating & length, then the more likely we are to be able to find something on the shelf. In stock makes the process both quicker & easier. If elements are required STRAIGHT or NARROW U BENT (ie, <=50mm fixing centres) then lengths will have to be close enuf. But if we can squeeze in a W shaped element, then this allows the “middle leg” to vary according to what lengths are available on the shelf. Likewise, if you can be flexible on power rating, we may not have sufficient 1000w elements to hand, but if you could take 1250w, 1333w, or perhaps 750w, then we are better able to accommodate your needs quickly & cost efficiently.
If no such “Wiggle Room” exists, we can make elements to exacting specifications. These elements are filled, rolled, annealed & dried out overnight in an oven specifically to your needs. This is likely to add a further week to your leadtime. If you are needing large numbers of elements, ie, 30+, it won’t affect the price too much. For manufacturing runs of lower volumes, the price is going to rise markedly. The lower the number, then the higher the price.
It’s best you know all of this, and factor it in, ahead of our conversation. I want you to be a satisfied customer, like all the Good Folks in our Testimonials.
Straight Heating Element Background Information.
Precision Wound Resistance Wire
Nickel Chromium coiled resistor. Wound precisely to provide exact heat requirement. Each individual spiral being thoroughly chemically washed to eliminate contamination and give a longer element life.
The connection between terminal pin and resistor is securely made by electronic welding or crimping.
The resistor coil is centrally located during manufacture and insulated with high purity Magnesium Oxide powder. When compacted by rolling, the magnesium oxide powder provides excellent thermal conductivity and dielectric strength.
Incoloy800 by default, but other sheath material is available depending on individual customer’s requirements and applications. All heaters are fully annealed to allow forming.
All heaters are sealed during manufacture to protect against moisture absorption during storage. This will not however serve to protect against liquid infiltration and chemical attack. Various sealants are available for special conditions. Please ask about special requirements.
Insulation and Threaded Terminals
4BA terminals by default 3.6mm ⌀, but can be spade, saddle or shell post terminals if required.. Ceramic or mica insulators ensure the electrical insulation of the terminal stud from the sheath. The standard threaded stud provides a quick and easy termination. Please ask about special requirements.
Industrial Heating elements are a resistance coil wire (producing heat), encased in magnesium oxide (the white powder, compacted by rolling down from 10mm to 8mm, for protection of wire & insulation purposes, bizarrely) encased in a usually stainless steel tube.

Just for clarification, an Immersion Heater (see below) is 3 such elements (as image below) on a screwplug with a terminal box housing the connections. Cuz we all speak diffrent!
