  • I love the De'Longhi toasters, but where can I buy a two slice model?

    Unfortunately two slice models are not offered in the UK as demand is relatively low for these models.

    Care should be taken if purchasing a two slice model from European shopping sites because the plug and voltage may differ from UK requirements.

  • My convector heater has a metal frame but has no earth wire - Is this normal?

    Convector heaters are typically Class II appliances. This means they have double insulation. To confirm this there will be a symbol on the heater of a square within a square (see left). Double insulated or Class II electrical appliances are products that have been designed in a way so as not to require a safety connection to electrical earth.

    Class II insulation provides sufficient barrier to protect the user and are independently safety validated. 

  • Will a convector heater suit my needs?

    Convection heaters operate on the principle that warm air rises and they take advantage of the natural convection effect produced by warm air to distribute heated air throughout the room.

    They are light and easy to carry and can be wall mounted. They provide steady, silent heat. Some models come with fan assisted features to speed up heat distribution.

    They are ideal for medium-term use but they do not maintain heat once switched off.

    For more information please see our heating guide.

  • How much does it cost to run my heater?

    It is very difficult to accurately determine how much it costs to run a heater within your own environment. It depends largely on the type of house, size of room and quality of insulation.

    However the maximum the heater will cost will per 1 unit of electricity per hour, per kilowatt of heat. For example, if you have a 2KW heater the maximum it will use is two energy units per hour. Oil filled radiators are more economical to run because they retain heat longer and power demand through the temperature control is called upon less frequently. Electric heaters heat only the room you are in and not the entire house, providing extra heat only where required and helping to optimise energy consumption.

    Electricity costs vary across suppliers. If you check your bill you will be able to find out how much you are paying per unit of electricity.

  • How long is the cable on the De'Longhi heaters?

    Most Delonghi heaters have a cable approximately 1.5m in length.

    Extension leads are not be used with the heaters as their rating is likely to be inadequate for power level required.

  • What precautions should I take before using my heater?

    • Always check the appliance and the power cord for signs of damage or deterioration.
    • Never cover the appliance, even temporarily, to prevent the risk of overheating.
    • Keep the appliance away from flammable objects.
    • Completely unwind the power cord whenever using the appliance
    • Do not let water penetrate into the appliance
    • Make sure the appliance's rated voltage corresponds to the mains power supply.
  • Do any of your heaters contain PTFE?

    None of the De'Longhi heater parts contain PTFE type materials.

  • Do all filter machines produce the same results?

    The straight answer to this is no. The requirement to produce the very best brewing and extraction rate is a science and there are very few coffee machines that deliver this. De'Longhi machines observe the precise measurements required to product the coffee of your choice to its optimum extraction ensuring that you get the very best coffee drinking experience.

    Some of these key factors are:

    • Using fresh water. Filter coffee is 98% water so using fresh water is essential to the quality of your coffee. You should consider using filtered water which will also reduce the risk scale build up in your machine.

    • Using the correct coffee grind. If the grind is too fine/small then water will pass through too slowly causing over extraction, coffee will taste bitter and thin. On the other hand if the coffee grounds are too coarse/large water will pass through too quickly and under extract, coffee will taste flat and weak.

    • To ensure that you brew a balanced cup of coffee you should use the correct proportion of coffee to water. More or less will result in a stronger or weaker coffee. The ideal ratio is 60g per litre of water. Typical 10 cup machine at 1.25litres will require 75g of coffee. All De'Longhi filter machines are supplied with a measuring spoon.

    • Correct brewing temperature. The best temperature to brew coffee is between 92-96°. At cooler temperatures the aroma compounds will not be extracted and you won’t extract the full flavour of the bean. Too hot and over extracting will cause a bitter, astringent taste.

  • How important is the type of coffee I use?

    The type of coffee is dependent on your own taste, although care should be taken to ensure the type of grind is suitable for the machine you will be using.  

    For pump espresso machine use a finer espresso coffee, and for filter machines use a coarser coffee blend suited for filter coffee machines. Most coffee is labelled to ensure you are able to select the correct type of coffee.

    However the best coffee in the world will not taste to its fullest unless the delivery of the coffee is exceptional. Please see the related questions for more details on how to ensure the very best results from your choice of coffee.

  • What is filter coffee?

    Filter or drip coffee is made by hot water passing through ground coffee.

    Hot water is filtered solely under the pull of gravity. When water comes into contact with ground coffee, the flavours, colour and aroma from the coffee are extracted and dissolved in the water. This is known as extraction.

    It is important to use ground coffee suitable for filter machines, and not espresso coffee, because it has been specially prepared for the purpose. There are many excellent brands to choose from, which are available from your local coffee specialist or supermarket.
