Generator Size For Kettle or Hot Water Urn?

by Sharon
(Newcastle upon Tyne)

I have it suggested that I should use a generator and hot water urn for my pop up tea room rather than the gas I have been using (this is to get round having a gas safety certificate).

The person from the council seems to think that I can get a generator for £100, and thats what other similar businesses use. However the hot water urn I have takes 1600w to boil and keeps hot on 150w. So the generator I would need would be large one, that is noisy and expensive? Kind of like this one?

And am I right in thinking that a kettle would take even more power?

Thanks for any advice

LPG Generator
by: David-

Hello there,

If you need to get a generator purchase a dedicated LPG generator these are more economical than dual fuel generators. Also, consider some sites/pitches will not allow diesel/petrol generators because of ground contamination issues.

Many people are buying catering vehicles with dual power sources and so have to depend on a generator. It's much better to have all equipment running on LPG which negates the need for an external power source.

Greengear does a range of dedicated LPG Generators which may be a good choice for your catering needs.

Hope this helps.

Stupid question alert!
by: Anonymous

Considering buying a generator for mobile drinks trailer. Just cannot understand all the jargon...
We have sockets inside the van and a 'hook-up'. Lots of talk on here about how much more cost effective gas is to run equipment but (really stupid question alert...) do they mean "definitely get an LPG generator OR is it recommended to buy equipment that runs of gas directly and therefore we would need to bring a gas supply into the trailer. Sorry to be a complete idiot about this but completely new territory for me.

Duel fuel generator or not?
by: Carinna

I have the exact same issue... i have sockets in my unit all attached to one cable to plug into mains or a generator. I need to run a 35litre tea urn, lights, fridge etc.
These duel fuel generators, would i still plug my mains supply into it?
I probably sound rather stupid here but habe no knowledge of this stuff & am in a hurry to get everything set up as am tendering to get a place at a festival this month! I hope somebody can help me?
Can somebody share a link on the generator i need please?

I agree with Brian, get a gas certificate for your urn. Generators are very noisy and will turn off customers, they cost a fortune in fuel also.
Best of luck with it.

Generator Size For Kettle
by: Brain

Hi Sharon,

Kettles are generally 2000watts, the overwhelming majority of caterers use LPG gas fired appliances - because of cost and compact energy capacity far outweigh any disadvantages of needing a gas certificate?

Generators have ground contamination issues when run on petrol/diesel, most events require LPG gas fuelled generators. Useless you have access to a mains hook up gas will is the preferred and least costly option.

Hope that helps
