FAQ

A heat pump extracts low temperature energy from the environment and increases its temperature for heating purposes. Heat pump efficiencies are normally quoted as the coefficient of performance of the system, these are typically in the range 3 to 5. In other words, extracting heat from renewable sources requires just 1kW of electrical input in order to generate 3kW to 5kW of heating output. Heat pump systems therefore, are 3 to 5 times more efficient than fossil fuel boilers and are more than capable of warming a house completely, even during the lowest winter temperatures. The increasing popularity of these heating systems is reflected by their overwhelmingly successful application in the cold climates of Scandinavia.

The inverter technology is integrated in the outdoor unit. The inverter technology can be compared to the technology in a car: ” The harder you push your accelerator, the faster you go.”

An inverter unit will gradually increase its capacity based on the capacity needed in the room to cool down or heat up the room. The non-inverter can be compared with switching on or off a lamp. Switching on this type of unit will start to run on full load.

Advantages of the inverter technology:

• You reach much faster the comfort temperature you want
• The start-up time is reduced by 1/3
• You save a lot of energy and also money : 30% less power consumption
• Avoids cycling of the compressor meaning that there are no voltage peaks
• The energy consumption cost is reduced by 1/3 (compared to normal on/off units)
• No temperature fluctuations  

When the air flow is set to LOW, the amount of air flow increases when the overload control is activated. (“Overload” is a condition in which the air conditioner operates under excess load. Overload can be caused by dirty filters.)
