• LPG and Natural Gas Appliances

    What is the difference between LPG and natural gas appliances?

    LPG and natural gas appliances work at two different pressures.

    Natural gas works on 20Mb pressure, whereas LPG works on 37Mb.

    When you are about to purchase a new gas appliance, always ensure you buy the right one for the type of gas you use.

    LPG and natural gas appliances are mostly the same, the only difference being the jets that let the gas through.

    Sometimes the air intake to the burners has to be adjusted when changing the jet. It will all depend on what type of appliance it is.

    All gas appliances come with an installation manual, which has all the details of the installation and converting to LPG.

    Some LPG appliances are made only for mobile homes and nothing else.
    You cannot use them in your everyday home.

    So what is the difference between LPG (Propane-Butane) and natural gas?

    Natural gas is the most commonly used gas supply in properties throughout the United Kingdom.

    Properties without natural gas have the option of using LPG as an alternative source of gas.

    Most mobile homes use LPG gas bottles to supply their appliances with gas.

    Some mobile home sites now have a bulk storage LPG gas tank that supplies all the mobiles on site.

    Installing a natural gas appliance onto an LPG supply could be potentially dangerous.

    An example of this would be, installing a natural gas hob onto an LPG supply, lighting one of the gas rings.
    The flame would be extremely high and out of control.

    The reason the flame would be very high is due to the gas pressures being nearly double.

    If you look at an LPG jet and compare it to a natural gas jet, you will see they look the same until you look at the hole in the middle where the gas comes through.

    The LPG jet has a smaller hole because LPG works at nearly double the pressure of natural gas so.

    You can see how important it is to ensure you buy the right appliance.

    Recently we were asked to service a gas fire, the customer complained of the fire coals sooting up and the flame being extremely high.

    On inspecting the fire, we found it was only for natural gas and not LPG the fire had to be disconnected and made safe.

    The customer told us someone claiming to be gas registered installed the fire sometime back for them.

    They tried to contact the installers to have the fire serviced but had no joy then called on our service.

    They were lucky that they did not use the fire very often in that it could have been disastrous had they used it more often.

    We advised the customer to contact GAS Safe, the governing body for all gas installers.

    It is so important to check when purchasing LPG and natural gas appliances.

    When purchasing any gas appliance online, be extremely careful what you buy. Some adverts may say it can be converted to LPG when, in fact, it cannot. So be extra careful what you purchase.

    Always ensure you buy the right one for the type of gas you use and
    Never try to install the appliance yourself.

    Always use a gas safe registered engineer to install your new gas appliance.

    LPG and natural gas appliances may look the same, but, as you can see from the fire above, they work differently and could be dangerous if installed on the wrong gas type.

    Gas hobs are the most common appliance to be converted over to LPG.

    Many people who don’t have natural at their property gas like to cook with gas, so they opt for an LPG gas hob.

    Central heating boilers are another story some, cannot be converted to work on LPG.

    It’s always best to buy a boiler already converted to LPG if you can.

    Most boiler manufacturers produce a limited number of LPG ready boilers.

    If in doubt when searching for your new gas appliance, seek help from an experienced gas engineer who is registered to work on the type of gas you use.

    LPG and natural gas appliances need to be installed by a registered gas engineer by law.

    Anybody installing a gas appliance LPG or natural gas not registered is breaking the law you, may also find your property insurance becomes void.

    If your new appliance is LPG, check that the engineer is LPG registered.

    There are more natural gas engineers than LPG. It’s easy to check if an engineer is registered.

    All gas engineers in the united kingdom are issued a gas safe card,

    Ask the engineer if you can look at their gas safe registration card.

    These gas safe cards have details of what appliances they can work on on the front will be a picture of the engineer presenting you the card.

    If the picture is not of the person showing you, ask them to leave as they are not registered to work on gas.

    To double-check a gas engineer visit the Gas Safe register and follow the instructions.

    You will see a box that says check an engineer, enter the details requested, push enter.

    Next, you will see everything the engineer can work on, including the type of gas.

    If this engineer in question is ok to work on your appliance and you are happy with the costs, ask them can they give you a gas certificate on completion?
