Sighted as regularly as rocking horse do-doos, a 1.75″BSP immersion heater has a circumference of 168 mm and a diameter of 51mm, thus it has options element-wise.

If only single phase is required, you could employ 2 looped elements and one stat pocket. Two elements commoned up at both ends, job done.

If 3 Phase is required, needing 3 elements, then the 3 elements would only be U bent. It is not possible to loop the 3 elements to reduce the watt density, as the resulting element bundle would not fit thru the hole. On the plus side, this arrangement would enable 2 stat pockets to be fitted, if needed.

If you are unfortunate enuf to be tied to 1.75″BSP, call Jamie on 07897 246 779 to discuss your requirements.

Close, but no cigar, 2″BSP is a good enuf screwplug size (circumference of 187 mm and a diameter of 57mm) in that it is not limited as to number or looping of elements, as are it’s smaller brethren, but due to it’s scarcity, you are unlikely to find it on the shelf, in stock, for quick delivery.

My best suggestion is to be very accurate in your G##gle search term, ie, ‘2″bsp 3kw 20″ single phase immersion heater’ and try and find some cheap, eastern manufactured, one element tat, for about £30, and cross your fingers.

Problem is, as with typing that previous sentence, the inch symbol confuses G##gle with the “IT MUST HAVE THESE WORDS EXACTLY IN THE BLOODY SEARCH RESULTS” speech marks, which doesn’t help.

If you don’t want to go the disposable route, and are happy to part with a coupla hundred quid, and wait a coupla weeks for bespoke heaters, full details, specification & purchasing advice are available at Immersion Heaters UK. Call Jamie on 07897 246 779.

Needing a 2.5BSP Immersion Heater is highly unusual & rather unfortunate circumstance to find yourself in. My condolances.

There is no benefit to the extra size (circumference of  236 mm and a diameter of 72mm), over & above 2.25″BSP, which is the Industrial standard here in the UK.

In my experience, nobody makes 2.5″ heaters, cos they are as rare as hens teeth. By all means, let me know if you find some, & I will share on here.

Instead it is normal procedure to take a standard, stock 2.25″BSP heater, and screw one of these onto it…

Full details, specifications, buying advice, etc, can be found here, so Call Jamie on 07897 246 779 for a consultation.

As rarely sighted as rocking horse poo, a 1.25″BSP immersion heater has a circumference of 131 mm and a diameter of 42mm, thus it is only possible to fit 3 x 8mm U bent elements and 1 stat pockets onto the screwplug, and thus it could be a Single or Three Phase immersion heater, 1-27kW. It is not possible to loop the elements to reduce the watt density, as the resulting element bundle would not fit thru the hole.

If you are unfortunate enuf to be tied to 1.25″BSP, call Jamie on 07897 246 779 to discuss your requirements.

The smallest screwplug immersion heater I have ever sold, and as rare as a pile of Rocking Horse Sh1t, a 1″BSP Immersion Heater comes with some serious limitations

With a circumference of  104 mm and a diameter of 33mm, it is only possible to fit 2 x 8mm U bent elements and 1 stat pocket onto the screwplug, and thus it would have to be a Single Phase immersion heater.

###PLEASE NOTE, 1.5″BSP MEASURES 1.8 – 1.9″ ACROSS THE THREADS.###

Shop for 1.5″BSP Industrial Immersion Heaters

The domestic standard screwplug size here in the UK, 1.5″BSP Immersion Heaters are not our stock in trade, 2.25″BSP heaters are, but we can do 1.5″ to your exact specifications in a coupla weeks leadtime.

With a circumference of  150 mm and a diameter of 48mm, it is only possible to fit 3 x 8mm U bent elements and 2 stat pockets onto the screwplug, and thus it could be a Single or Three Phase immersion heater. It is not possible to loop the elements to reduce the watt density, as the resulting element bundle would not fit thru the hole.

With these inbuilt limitations, and a host of folks selling cheap, one element, massive watt density heaters online for peanuts, I often advise potential customers to go buy something cheap, not cos I want to live in a disposable society, but my stuff is heavy industrial gear which is not going to come cheap. It could cost 10 times as much as some of the heaters I have seen, but I cannot in all good faith tell you it will definitively last 10 times as long. Particularly when people are proving a theory or application, do it on the cheap, I would, cos I’m half Scottish, Half Jewish & half Yorkshireman. But live in Sunny Tammuff.

Full details and buying guide can be found on our webpage here.

Call Jamie on 07897 246 779 to discuss yout 1.5″BSP needs, so we can co-design the best heater for your application.

###PLEASE NOTE, 2.25″BSP MEASURES 2.5″ ACROSS THE THREADS.###

Starting with not necessarily the biggest, but certainly the best & most common, 2.25″BSP Immersion Heaters are our stock in trade. As the industrial standard in the UK, most people want 2.25″ so that is what we keep on the shelf. As 2.25″ accommodates 3 elements, and thus can be Single or Three Phase, stock is basically the 3 times table, 3, 6, 9, 12, 18, 24 & even a 27 if needs must.

Full details and purchasing options can be found here, but basically…

With a circumference of  206 mm and a diameter of 65mm, it is possible to fit 3 x 8mm LOOPED elements and 2 stat pockets onto the screwplug, and thus it could be a Single or Three Phase immersion heater.

Use 2.25″BSP weld bosses, as it is the industrial standard and more available off the shelf.

If you are one of that rarest of breeds, the Rich Brewer, you can go for DN80 or even DN125 hygenic connections, which allow you to remove the heater fairly quickly and easily for cleaning purposes. BlogPost to follow when time & life allows, but in the meantime, have a shufti here – Removeable Brewery Heaters

Heat rises, put the entry ports low, then it’ll agitate itself to a degree.

BONUS ITEM – if heaters are low in the vessel, you can switch them on as soon as they are covered with water, heating a small volume of water, which has gotta be a good idea and save a fair chunka time, no?

Don’t position the entry ports on the same level, as this will cause elements to clash in middle when inserted.

How not to do it – (2.5″, in the belly not the bottom, clashing like jousters)

A better job –

Any suggestions, input, constructive criticism, etc, greatly appreciated.

Thanks for visiting.

I started a post about my BI18 Brewery Immersion Heater, which rapidly twisted to being about “The Holy Grail of Brewing – Easy Clean Immersion Heaters”, so I shall replicate here in a seperate post, in the hopes of finding more collaborators via serendipity & G##gle’s algorithms.

This is something I have been playing at and toying with for years, which now deserves some serious focus and attention. If we can work together to improve the unfortunate end to the otherwise beautiful brewing day, life will be better, brewers will be happier, hangovers will be shorter, tax will be lower, politicians will be honesterer…..

Sorry, I went off on one then!

Enjoy.

=============================================================================================

Here is my friend Alex from the Green Duck Brewery in Sunny Stourbridge using one for a guitar solo. Worry not, it’s not plugged in! Mind you, neither is he.

Having spent a little time with Alex & Nathan brewing, trying to learn as much as I can about the process to be better able to understand & problem solve, two things struck me.

Firstly, banging heavy rock music is a subtly essential part of the process.

Secondly, the worst part of the day is the last part of the process, cleaning that awful grey sludge off the elements, in a process that I think Nathan refered to as “Winking the Elephant” whatever that means?

This involves some serious welly trouser type things, 3M Scotch green scouring pads & wire wool, and an awful lot of elbow grease & swearing. To have that “Turd in the Swimming Pool” of a job hanging over your head all day, somewhat spoils an otherwise pleasurable, if damp, day.

So I have made it my mission, my Holy Grail to make this better, to remove said turd from the horizon. I’m not clever enuf on my own, so let’s Collaborate. Please call or email me with mad ideas from other areas of industry or applications, share ideas you have tried that failed, & why, or just to tell me how you do the cleaning process. I have spoken to Brewers cleaning with acids, lemon juice, caustics (FFS, NEVER USE CHLORINATED CAUSTIC! Nameless Brewery did, shiny new heater very dead inside a month), but surely the prize for Best in Show thus far, albeit with an expensive DN80 removeable Heater, goes to Nial Fitzgerald at Stone Barrel Brewing in the Emerald Isle for this inspired creation of purest beauty…

My Collaborator In Chief, Dave, and I had visions of shiny stainless steel tubes, munsen ringed to a wall, sold for huge sums of money to that rarest of breeds, the rich & shiny obsessed brewer. And Niall goes and achieves the same easy cleaning with a bit of drain pipe & some gaffer tape! I love it! Basically, the idea is to take the heater out of the vessel, (intermittently or every brew is question 1), soak it overnight in ???, then jetwash/steamclean the bugger off in the morning. Hopefully with nonchalant ease.

My first question to anybody brave enuf to read this far is, what precludes the same thing from being done with a screw in (considerably cheaper) heater such as my BI18 fan favourite, with which this ramble started, way back when?

If it is the faff of disconnecting power, could one of these not be fitted?

The only other idea currently percolating around my head is this…

A heater with elements bent in such a way as to allow flexing for insertion/removal, supplemented by possibly a cleaning block with the correct sized holes to clamp a scouring pad around the 2 legs of the element. To facilitate easier winking 😉

Alex the Guitarist, above, is a willing volunteer & test pilot, but many heads make light work, and I want to build Win-Win relationships with as many folks, particularly brewers, as possible. So, gissa call on 07897 246 779. Cheers, Jamie.

By far our biggest seller to Brewers, our favourite customers, is the 18kW 2.25″BSP 990mm IP65 beast that is the BI18.

It is good value for money, at a tickle under £300 (and if you call me on 07897 246 779 and say BLOGPOST, BABY! you will receive a healthy discount) and at a tickle under a meter in immersed length, it is a good fit for most vessels.

The BI18 benefits from –

  • 10mm diameter Incoloy 800 elements, with huge great wide open spaces between elements for cleaning purposes
  • 2.25″ BSP Brass Screwplug (suits 95% of brewers, SS bespoke II Range available for other 5%)
  • 6″ or 150mm inactive or cold end
  • 33″ or 830mm  immersed length
  • ABS IP65 terminal enclosure rotateable through 360 degrees
  • 10.7 w/cm² or 69w/in² watt density (the lower the watt density, the less sh1t sticks!)
  • 415v 4 wire STAR by default
  • complete with 11″ thermowell.
