An Immersion Heater…
…is usually 3 Heating Elements, usually Incoloy 800 sheathed (“A Superior Stainless Steel“)…
…sometimes U bent as in Element image, sometimes looped, as in Immersion Heater image, to fit more element into available space, thus lowering the watt density & extending it’s working life. Usually on a screwplug, usually Brass 2.25″BSP. Usually with a terminal box, hopefully IP 67 . Commonly to screw into a vessel, usually Stainless Steel, generally through the side, via a weld boss, welded to the tank.

Immersion Heaters UK – Useful Stuff.
On this site, you will not only find an online catalogue of our core range of products. You’ll find tips, advice and guidance, as well as links to other resources to make your life easier, including our heating calculators.
On our blog, ElementsOfHeating there is a wealth of relevant and useful information, such as an explanation of what a heating element actually is. Also we have a full description and explanation of the component parts of a screwed immersion heater and my best punt at explaining the joys of watt density, and it’s crucial importance when choosing the most appropriate immersion heater for water, oil, and breweries. Also available is an informational entry about the process we go through when designing immersion heaters generally.

Sidetracked onto our Sister Site?
If you now realise that what you are in fact searching for is a Heating Element, as opposed to an Immersion Heater, you have two options. You can stay on this website, research Heating Elements, find what you need, & then call Jamie on 01827 215684.
Or you can go to our sister site, HeatingElements.co.uk where you will find additional information, exampled below, and you are able to buy online, should you wish to avoid a long telephone conversation with Jamie, about Life, the Universe & Everything. Or perhaps you love banks & their 2% charges. I don’t. So please call Jamie on 01827 215684.
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.
