2.4kw electric max rolling boil

[Whammybar]

Hi

Does anyone know if it would be possible to get 46 litres of wort to good rolling boil, in a stainless steel pot with one 2.4kw element?

Thanks

No.

1 struggles to get 30l to a boil, let alone rolling boil.

I agree with Wabby.

I have one of these ...

... and my 32 litre pot is insulated as per the photograph.

Even with 5.5Kw of heat available, on a cold and breezy day, it takes nearly an hour to bring 28 litres of wort up to the boil and only just gives me the "rolling boil" that I require; so I reckon 2.4Kw wouldn't be adequate even if the boiler was fully insulated.

Unfortunately I don't have the outdoor space for propane burner. Nice insulating jacket though

So am i safe to thing I could probably get away with a 23-25l batch in the 56l pot with 2.4kw element

They sell a 72l pot with two elements, but seems a bit big for my kitchen lol

Thanks

You would probably get away with 2.4Kw with a 23-25 litre batch.

I used a 2.4Kw element in an uninsulated 25 litre FV for over a year without a problem ... :thumb:

... apart from losing the will to live waiting for it to come up to the boil. :whistle:

Enjoy! :thumb:

You can add a 2nd element to a 50 litre pot - assuming your kitchen electrics are up to running 2 x 2.4kw elements.

The pot supplier should be able to cut an additional hole for the second element and supply the 2nd element also.

2 elements in a 50l pot look like this:

I can get a full 30L to a rolling boiling with one 2.4KW element. 46L would probably be too much of an ask unless your insulation was very good and you didn't mind waiting an age. Two elements would be better.

My 3kw induction job easily boils 30l. Some people do 50l on them. Cost me £70 sh.

 

[Whammybar]

I mentioned getting a bigger pot to the Mrs... But got the death stare.

Think I'll get a 50L with 2 elements, guessing I'll be safe using the cooker socket and one of the wall sockets.

The first supplier I tried said they can't add elements :-? . Will try somewhere else, if not will have to suss out a Q max cutter

Thanks

Try brewbuilder for the pot with stainless tap fitted and 2 x 40mm holes cut for the elements.

Then buy 2 Peco elements and power cables from pecoservices - they were marked out of stock on their site but I bought one recently, they had them in-stock in reality. Ring them to check stock before ordering online.

i used to use an old single element in my first boiler which was donated by my dad when he upgraded his boiler and it always got to the boil, get a proper insulated jacket, will save you money and it will come to the boil quicker and hold its heat

I hate quoting myself but on this occasion it's because I need to retract the statement because:

1. I haven't got the Boiling Ring that I ordered.

2. The one in the photograph is nowhere near the 5.5Kw advertised.

This is the one I ordered.

https://www.amazon.co.uk/gp/product/6041755117/?tag=skimlinks_replacement-20

It is supposed to be 400mm x 400mm of pressed steel with the "swirl pattern" burner whereas the one I was supplied with is as per the link in my original Post and as per the photograph.

I have to confess my own stupidity. I actually thought "This seems a bit small." when I positioned the Boiler on top of it for the first time, then "This is taking a long time." when I brought it up to the boil thereafter.

At the moment it is in the hands of Amazon and the Supplier. I will let everyone know the outcome but I'm pretty sure that the boiler ring I have at the moment is only just over 2.0Kw!

I think the Mrs might be coming round to the idea of a 72l pot :) would this be too big for 23 l batches or does it not really make a difference?

Personally, I wouldn't think it would be a problem, and it always leaves the door open for much bigger brews.

To my mind, the only constraint will be that the amount of heat-loss that can occur with a much larger pot will mean that it will take more kilowatts (be they via a gas-ring or an electric element) to raise the temperature to boiling point and to then maintain the "rolling boil" required. :thumb:

My memory might be playing tricks but I'm pretty sure when I got my Ace boiler (30L) a couple of years ago it said it had a 1.5Kw element in it.
It gets up to mash temperature in the time it takes me to weigh out my grains and grind the pale malt. About 45 minutes I think. From there to a boil it takes 20 minutes or so and I have to say I do still find the `rolling boil' to be more of violent affair than I'd like.

As far as I can make out, most of the ACE 30L boilers have 2.5Kw elements in them ...

... which ties in perfectly with my experience of El Cheapo's 2.4Kw element and your timing.

The 2.4Kw element on El Cheapo (only a 25L capacity) also gave a boil that could spit wort over the side, so I also agree with your "more violent affair than I'd like" comment! :thumb:

Can you recommend what to make one from? I bet i am losing a ton of heat with my thin pot.
