We assume that a building with good insulation and good quality joinery will also have lower heat losses. Add to this slightly oversized radiators and continuous heating with a heat pump without interruptions, and the building can be heated even at temperatures below 60 °C....

A properly sized heat pump optimally heats or cools a space under average operating conditions. However, in extreme conditions such as very low outside temperatures, an electric heater or other additional source (if already installed in the building) is always sensible,...

The correct sizing of a heat pump is very important from two points of view: the cost and the coverage of the heat losses of the building. If you oversize your heat pump, you may end up with higher heating or cooling costs than...

The annual efficiency coefficient is not significantly affected by the heat pump efficiency data at extremely low temperatures. In our climate zone, extreme cold temperatures are rare and, if they do occur, they last for a very short time relative to the heating season. The temperature at night can...

The required output of the heat pump is defined by the heat losses of the building and the energy required for heating the domestic water. The consideration of the energy for domestic water heating is particularly important in low-energy and passive houses, where the energy consumption for domestic water heating can be...

COP = Thermal energy / Electricity What do the figures quoted by heat pump manufacturers mean and how do they compare? COP - Coefficient of Performance By definition, the COP (Coefficient of Performance ) represents the ratio of the electricity used for...

Choosing a heat pump, a comprehensive guide to choosing one Different types of heat pumps work on the principle of transferring heat from one medium to another. In doing so, they take advantage of natural heat sources such as air, ground or water and convert them into usable heat for...

Modern heat pumps are suitable for all types of buildings, such as new constructions, energy-saving houses, apartments or older buildings, where the heat pump is connected to the existing heating system. The building can have radiator, surface or manual heating. Optimal operation of the heat pump system will be...

More and more investors are choosing heat pumps as a source of heating, so let's summarise the arguments that matter most: A heat pump can heat or cool buildings and provide domestic hot water. It does not require a furnace and can be placed anywhere where there is 1...
