A full description and explanation of the component parts of a screwed immersion heater is available here on our blog. Also available is information about how best to choose an immersion heater for water, oil, and breweries. Also available is an informational entry about the process we go through when designing immersion heaters, generally.

18kW HLT Brewery Heater – Hopefuly Useful Information

We understand your need to get water from one part of your process at 70ºC, up to the boil as quickly as possible. Therefore this demand for lots of power needs to be balanced with a maximum immersed length of about 1m. The more element we can squeeze into the available space, the more we are able to reduce the watt density of the elements. Therefore, it may be worth having a look at our Blog entry, in which I have tried to explain the importance of watt density and its relevance when choosing and using a brewery immersion heater.

18kW HLT Brewery Heater – 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.

BSP Screwplug sizing causes much consternation, so click here for the full shilling BlogPost on ElementsOfHeating, but hopefully this suffices for most –

0.25” 0.518 41
1/2 0.825 66
5/8 0.902 72
3/4 1.041 83
7/8 1.189 95
1 1.309 104
1 & 1/4 1.650 39.5 41.5 131
1 & 1/2 1.882 44.8 47.7 150
1 & 3/4 2.116 51.2 53.5 168

2 &1/4 2.537 62.5 65.4 206.4
2 & 1/2 2.95 72.4 74.9 236.2

Simple Version.

So, simply put, I am hoping you measure the screwplug of your dead heater at 65mm.

Or alternatively, the hole in your vessel at 63mm.

Either way, this measurement is best acheived with a Vernier Gauge if you have one handy. A tape measure and a steady hand will have to suffice if not. As a backup, a bit of string or cotton, wrapped around the circumference of the dead heater screwplug, then measured on the tape measure, should give you a good approximation.

The safest, 100% way to check your screwplug size is to wander casually into a Plumbase, Screwfix, or the like, and ask for a nut of your guesstimated size, then screw it on to the heater. This avoids the unlikely, but still possible accurence that you are the possessor of a “Bastard Size” which may have a different thread pitch, number of threads per inch, etc.

We hope you find the site intuitive & easy to use. If you have any suggestions, feedback or corrections, please contact Jamie at ImmHtr@gmail.com or on 01827 215684. Always open to new learning & Collaboration!
