Cooking Power: Gas & Electric Explained

This guide explains the key information you need to know on gas and electrical supplies, used to power your kitchen:

 

Electric power:

  • Electricity is supplied from either a mains power supply or from temporary generators. Before it gets to the sockets it will go through a circuit breaker, which is a device that ensures not too much power is delivered.
  • Different appliances require different ratings of power, usually related to their size and their heat output. All of our appliances will have their power rating listed on their product page on our website. For example an Electric 6 Burner Range requires a 32 Amp Three Phase supply.
  • The various power ratings all have their own associated plug sockets and these always have to match the power rating.
  • There are two key elements of power socket ratings:
    • Amps: This is the measure of the maximum current flowing to the appliance. The amp rating for Jongor catering appliances starts at 13 amps and goes up in increments to 63 amps.
    • Number of Phases: In simple terms, a three phase supply is three single phase supplies in one cable, so delivers three times the electrical power. Single Phase is denoted by blue plugs and Three Phase is denoted by red plugs. The exception is 13 amp plugs which only ever come in single phase.

 

                   

                                  13 amp                                                    16 amp single phase                     16 amp three phase              


              32 amp single phase                            32 amp three phase                             63 amp three phase                                          

 

 

  • If you already have a power supply at your location, you may be able to tell what power supply is available by taking a look at the sockets and it should have the power rating denoted on the socket. If you don’t have the correct sockets available, then an electrician should be able to advise you on how to bring in the correct power to you.
  • Extension leads or multi plug adaptors cannot be used with any of Jongor’s appliances. Extension leads will burn out and using a multi plug will often mean tripping the circuit breaker, as the number of amps drawn by the multiple appliances will exceed the socket rating.
  • 13 amp sockets are for indoor use only and only 16 amp sockets and above are suitable for use outdoors.

 


Gas:
Gas catering equipment can be powered by LPG [Liquid Petroleum Gas] or Natural Gas (which is also known as Mains Gas) and appliances are set up differently depending on which one of these they use.

 


About LPG:

  • LPG is manufactured from refining fossil fuels, in the same process that we get petrol, diesel and jet fuel.
  • For catering uses it is supplied in gas bottles, where is stored at a very high pressure and in liquid form. When it comes out of the bottle it transfers to a lower pressure and therefore turns into a gas.
  • For catering purposes LPG is generally supplied using Propane gas, as it has a very high heating ability. Propane is supplied in red gas bottles.
  • Another type of LPG is Butane. Butane is generally used for low draw appliances such as our boiling rings, and is supplied in smaller blue bottles. Note that Butane bottles use different gas regulators (the connection between the bottle and the hose).
  • Propane bottles cannot be used indoors, unless a risk assessment for the building is completed by a qualified person and no more than 100kgs of propane gas (i.e 2 x 47kg bottles) are in use. 
     

Jongor and LPG:

  • Jongor supply Propane bottles and regulators as our standard LPG supply.
  • Almost all of our gas appliances require a 47kg Propane bottle to be able to deliver the correct pressure for the appliance to operate safely. There are a small number of items that can operate safely using a smaller 19kg bottle and there are some items that require two 47kg bottles to operate safely. These items are listed on our gas ordering page and our team members can help you select the correct number of bottles during the order process if required.
  • Where there is a single appliance operating alone, this can be connected directly to a gas bottle by a competent person
  • Where multiple appliances are being used in conjunction with each other, our Installation Team can create a bank of gas with a gas line, just like in a commercial kitchen, where we can connect multiple appliances to one temporary supply.

 

Natural Gas

  • Natural gas is extracted as a gas from the ground or sea and mainly comprises of methane.
  • In the UK, this is the gas that many of us receive at home or at work if we are connected to the mains gas supply, which is why it is often referred to as ‘mains gas’. 
  • The gas has different properties to LPG gas and therefore some of the internal components of catering appliances, such as burner jets, are different to that of LPG equipment.


Jongor and Natural Gas

  • Our equipment is set up to work with LPG as standard, but most of our equipment can be modified to run on Natural Gas. You can find out if an appliance can be modified by checking the product page on the website where it will state under the ‘information’ tab whether it can be converted from LPG to Natural Gas.
  • Modifying equipment is undertaken prior to delivery by one of our Gas Safe engineers. We have both Natural Gas and LPG supply lines in our service bay, so we fully test the equipment on its new supply before it receives its certificate for safe use.
  • When connecting to a Natural Gas supply on your site, we can connect to a pre-existing gas connector, but we cannot cut into a gas pipe to create a new connection. If you do not have a gas connector available on your natural gas line, you will need to arrange for your local qualified gas installer to fit this for you.

 

 

Gas or Electric: Which is best for me?

Gas summary:

  • Gas appliances are much quicker to reach temperature over electric appliances and the ability to manually control the size of flame allows for more direct cooking control.
  • Gas appliances are slightly cheaper to hire than electric appliances.
  • However a gas installation will require a Gas Safe® qualified engineer to install and commission the appliances.
  • 60cm of free space is required behind the cook line to allow space for the gas pipework and access to it.
  • In a fixed structure or building, a kitchen will require a gas interlock and extraction system to be installed above any gas appliances for it to be commissioned within gas safety regulations.
  • In a fixed structure, a mains gas (natural gas) supply may already be available, which we can connect to.


Electric summary:

  • An electrical power supply is required either from a mains supply or generators, with the correct socket type nearby to the appliance.
  • If the supply is from a generator, the size and number of generators increases with the number of appliances. For kitchens of a reasonable scale, generators and their fuel tanks take up more space than an LPG gas bank. Generators also create noise which needs to be considered if close to dining areas or areas that are close to the public.
  • Electrical appliances do not emit carbon dioxide when they are in operation, which is not the case for gas appliances. However consideration still needs to be given to extracting excess heat, steam and cooking fumes from a kitchen.
  • In fixed structures and buildings, the power supply may already be there so there is no need for additional power to be brought in. Remember that the sockets you have must match the power rating for the appliance. A qualified electrician should be able to assist you if you do not currently have the correct power sockets available. 
  • In a fixed structure or building, it may not be possible to bring a temporary gas supply into the location, so electric could be the only power supply available to you
