Gas burner for 200 litre pot

[Horatio]

Hi all,

I've always used electricity to heat my pots and am looking at changing to gas. I have no idea when it comes to gas so could someone tell me what size gas ring I would need to boil around 180 litres of wort please? Do the Kw numbers equate to the same as element ratings; 7kw of elements would give the same heating potential as 7kw of gas burner etc?

Cheers chaps.

I use a 7 kW on a 50 litre brew length and it is just about enough. I guess you would want a lot more wattage for your brew length but I really dont know.

Something like this maybe. I'd sit down before you look at the price or the gas consumption.

have a play with the water heating calculator on here, it should give you some idea.

I use an 11KW gas burner on 130L, with no problems, but I have a heat shroud on the copper preventing massive heat loss from it.

Mine is the 400mm twin paella burner from hamilton . . .If you can fit it under I would Imagine the 640 Triple would fit the bill nicely

Do those burners support the kettle or do you have it supported by something else like bricks etc?

[Horatio]

Many thanks for the replies, I shall start looking at the suggestions.

I was wondering about that too. 180 litres is some weight to support! I was going to build a metal stand and sit the burner on it with a shroud as per Alemans's input.

[Hanglow]

Yeah I though if you couldn't get a suitable metal stand then bricks would be good. Would work as a wind/draught break too.

I'm using electric at the moment but am only doing smaller batches so am looking to see if gas would be good to step up to bigger batches.
I presume the paella burners would be good as you would get less scorching than from a jet wok burner or similar?

£250!

Maybe this instead? http://www.thepaellacompany.co.uk/high- ... urner.html bit smaller but do you think this would do?

might be worth going to ebay.es and search for Paella-Gasbrenner

Ok, I give up! Where is the water heating calculator? I can't find it anywhere?

One more thing. Is there a comparison between electric element wattage and gas burner wattage? I've searched google but can't seem to find and answer. I've found the formula for working out the size of immersion element I would need to heat a given volume of liquid by a given rise in temperature in a given time. But I can't find out how this would relate to gas burner Kws?

Follow the link in Aleman's post for cheaper burners.

Go for more kW in a gas burner because lots of that heat will "miss" the pot and heat up the planet instead. And then those folk in Somerset will be underwater a bit longer. Definitely build a head shroud of some sort.

As Boingy just said, a kilowatt is the same whether gas or electric, but with an immersed electric element, you are getting almost 100 % energy into heat, but with a gas burner - unless there is no breeze - the wind will take a percentage of the energy away to heat the heavens !

I have gas burners, but at the back of my shed there is little breeze

[Horatio]

Cheers Boingy, much appreciated.
The ones in Alemans link seem low on KWs? This one http://www.thepaellacompany.co.uk/high- ... urner.html comes in it just under 22kw for about £90. Or am I reading it wrong?

Cool. So it is just the loss due to position and heating up the brewery etc? I will be boiling in an out building; well ventilated and using a heat shroud etc. the 22kw burner should good then?
