  • What are the criteria for choosing a good air conditioner?

    The most important criteria to bear in mind at the time of purchasing an air conditioner are :the types of air conditioners, whether fixed or mobile, one or several units and whether it is also capable of heating by using a heat pump, cooling power, expressed in BTU/h or Watt. You may also consider: energy savings that it may provide, noise levels, dehumidification capacity, the presence of additional functions such as: a timer for programming, "sleep" to avoid temperatures dropping too low at the night, air filtering systems, etc. Finally, you must also take into account installation costs for fixed air conditioners and periodic maintenance operations.

  • What's the difference between a portable air conditioner and other types of air conditioners?

    Generally, air conditioners can be divided into three categories: Portables are a single unit, not fixed or mounted, and can be moved from one room to the next. Split Air Conditioners are equipped with one or more internal units fixed to the wall, and an external one. Finally there are climate control systems, designed to treat the air of an entire home or building.

  • What is required when using a portable air conditioner?

    Generally, portable air conditioners require space for the unit; a power outlet and an external window for the hose to connect to, allowing the hot air to be released

  • What are the pros and cons of a portable air conditioner?

    Portable air conditioners are extremely versatile units that can be easily moved from one room to another. They are ready for use without installation. However, it is necessary for the machine to be near a window or French door to allow it, through the tube provided, to remove hot and humid air from the air conditioned room to outside.

  • How can I choose my portable air conditioner?

    As for all air conditioners, it is necessary to know how many BTU/h are necessary to cool the desired area. The BTU/h calculation is given by a series of valuations on the type of area to be air conditioned:the type and size of rooms facing direction and sun exposure number of windows and types of insulation number of people who are usually in the area to be air conditioned

  • Can an air conditioner work on several rooms simultaneously?

    It probably can, but only if the two rooms are adjacent and there is good air flow between the two. However, portables are mainly designed to cool a single room.

  • Where do I place the air hose?

    Many portable air conditioners are equipped with kits that allow you to attach the hose to a window or glass door.

  • What happens if the hose is not long enough to reach the window?

    The exhaust hose is typically about 1 metre in length, and you must check before buying that you have enough space to position the portable air conditioner near a window or door.

  • What is the meaning of "monoblock air to air"?

    These air conditioners are so called because they both use the air to distribute cold into the environment, and in which to distribute heat outside.

Common FAQ's

  • How do I create a perfect and rich milk froth?

    • Use skimmed or semi-skimmed milk at refrigerator temperature (5°C).
    • On automatic cappuccino system you can also set your preferred froth level.
    • Milk deposit and dirt inside the milk circuit and tank can lower the frothing performances. Make sure to regularly clean the milk container following the user manual.
  • How frequently do I need to use a descaler and which kind of descaler product to use?

    • It depends on water hardness and on the usage frequency of the machine.
    • Some models are equipped with a water hardness tester to set the machine correctly.
    • Automatic machines (*) are equipped with a descale alarm.
    • A Descaling process on a non automatic machine is recommended after approximately 300 coffees or as soon as the performance levels drop on the machine.
    • Please use De'Longhi descalers only. Under no circumstances should you use sulphamic or acetic based descalers
  • Can I use any type of ground coffee to make an espresso?

    • No, only ground coffee can be used in espresso machines. Espresso requires a specific range of coffee grinding which is different to filter coffee or moka coffee.
    • Different types of grinding levels, even in the espresso range, can provide different tastes.
    • On fully automatic machines you can set your grinding level and taste preferences.
    • On pump machines the in-cup coffee flavour (stronger or weaker) can be adjusted by pressing the ground coffee differently inside the filter holder.
  • Can an air conditioner work on several rooms simultaneously?

    It probably can, but only if the two rooms are adjacent and there is good air flow between the two. However, portables are mainly designed to cool a single room.

  • What is an oil-filled radiator?

    Oil-filled radiators are among the most common electric radiators available, and heat the air by convection. An electric heating element heats the oil inside the radiator, which then transfers heat to the radiant surface, where it is exchanged with the surrounding air.

  • What are decibels - dB(A)?

    The decibel is the international unit of measure for noise.
    40 dB(A) is the noise level inside a library;
    120 dB(A), on the other hand, is the noise produced by a plane during take-off.
    For each increase of around 3 dB(A), the noise we perceive doubles.

  • Why are there different types of thermostats?

    The thermostat switches the appliance on or off at the temperature set by the user.The term "safety thermostat" refers to a simple temperature limiting device (a safety requirement in compliance with European legislation) that the user has no control over.
