110v Burco boiler

[Belter]

I can only lol at that....

I don't know where to start.....well for one you'll get 110V across both lines so that's that one out but I'm not getting involved any deeper. I clocked off at 4.00PM.

Sounds a bit odd. How would you ever get 110 on each phase? Unless the transformer is tapped as one leg earth then you'll get 55 on each phase. The other option you'd get 110 Line and 0 Neutral.

I said across both lines. The chap suggested you could only ever see 55V. Which is true on a Center tapped transformer from line to earth, because the fault current only returns through half of the windings. But you would still get 11OV across both legs.

Basically you get 55V on BOTH. There is no neutral in a SELV transformer.

And why you would need RVL (reduced low voltage) tea urn anywhere is beyond me.

Can you just imagine a site cabin full of 110V tea urns and toasters unless the chaps on site are brewing up while sat on there tool boxes in the middle of the job.

It's something that could only be dreamed up in the H&S dept.

Belter , building site 110v stuff dont have a neutral its a 2 phase 55v supply with the centre point earthed,meaning you only get 55v between earth and phase,or 110v between phases

Ah yes like a councils elf and satcey bod who insisted EVERYTHING being used outside must be 110V,including the sound rig,bands back line ,lighting rig, hospitailty ,catering etc etc,he went a funny colour when i told him it was 415V 250A or nothing. however 110v stuff aint just for building sites ive seen 1 or 2 outdoor caterers using it ,and also some fun fair stuff is 110V,

Hahaha I misread his comment. I Know you don't have a neutral on a site transformer. That's the whole point. Chances are you'll only really get 55v to Earth as you'll touch a phase and be an earth.you wouldn't get 110 on each phase but obviously would between them. I did try to explain that above. You do however have neutral on an 110v control supply with one leg earth.

option E - forget the burco power/element etc. cut a hole at the side/back and fit a budget kettle element or 2,
if close by to a brewer with a qmax cutter the right size it could be sorted for a fiver in an afternoon..

Haha, having just got rid of a squad of builders who were in my house for the best part of a year, I can confirm that they would have loved one of these!

The sticker on the box and on the bottom of the unit say 110v so seems pretty conclusive!

Looking in the base I expected it to be a bit more complex!
First thing to note is that the neon says 240v
The stat looks standard too: EGO branded marked 55.17022.030
The Strix controller is also standard.

I don't see any markings on the element but it looks different to the one in the ebay listing above. I haven't taken the controller off the bottom but I guess it's marked under there. I'll take another look at the weekend.

Not too keen on the kettle element plan - seems like too much of a hack - although I did think about making a boiler using kettle bits following instructions on this site before I bought the burco. Now that I have it I quite like the non- DIYness of it!

[Kev888]

I don't actually know, but I'd be surprised if burco made completely different boilers for 240v and 110v, I'd expect them to keep as much as possible common to both models. So I agree that with a bit of luck you may well be able to swap just a few components. Also, if its an urn rather than a wash boiler then you may end up bypassing the controls anyway, to get a full rolling boil, in which case there wouldn't be much to upgrade to 240v.

Site transformers are expensive and heavy, especially with a continuous rating at those powers (the continuous rating of the portable ones is frequently less than their quoted maximum power) and they're often not the most subtle things - mine sometimes trips the MCB as I switch it on. I would consider using one if I had a reason to run on 110v, but otherwise converting the boiler to 240v sounds a better solution to me 'if' your electrical skills are sufficient to do so safely.

another of the wall,suggestion,ardunio firing pwm at an ssr,set the maxim output to give an average of 110v,you could even add a tempreture probe..down side is you still chucking 240v into the thing,but for only half the time,so things like elements and lamps shouldn’t get 2 upset about the briefly over voltage

Is it this one?

If so these are normally interchangeable.

Slightly different- https://flic.kr/p/qNdhTL I'll swap it out and see how I go.

This may as well be Chinese!
