Heat Pumps - FAQ


The main questions about heat pumps: how much does it cost to install the heat pump?
Is it convenient? How much does it consume? How to choose it.

How to heat the house and how to save on heating?


Heat pumps can save on heating, reducing energy consumption and therefore costs up to 50% compared to a condensing boiler. Although powered by electricity, in fact, these machines use renewable energy, because they transfer heat from an external source to the environment to be conditioned or water of a heating circuit. In particular, the air-air and air-water heat pumps draw it from the outside air, while water-water or ground-water heat pumps draw from the water (groundwater, lake, river or sea) or from the ground , using a geothermal probe. With a heat pump, in addition, there are no direct emissions of C02, while the indirect ones emitted by our electricity system for the electricity generation are reduced of about 50%.

How much does it cost to install a heat pump?


The costs of a plant with heat pump will change depending on the capacity needed to heat and cool the building, and the dimensions and insulation of the same. There are heat pumps that enclose all elements of the system such as the domestic hot water boiler or heat pumps where the installer has to add the elements necessary to complete the plant.

What requirements are needed to install a heat pump?


There isn’t any special requirement for the installation of a heat pump as Clivet offers a wide range of heat pump systems, in order to meet the needs of the different types of building: New Nearly Zero buildingsblock of flats and homes in which there is no possibility of interventions on the building or equipped with radiators. To know how to heat a flat or a large house with a heat pump, contact Clivet specialized network of installers for a detailed quotation.

 

Where to install a heat pump?


Depending on the type, the heat pump can be installed in the technical room in the home, in the understairs, on the hallway, outside the house, on the balcony... Thanks to the expertise of the specialized technicians of Clivet sales network and service, for every building situation and every need of heating/cooling and air purification Clivet studies the right integrated system solution and this is then installed according to the client’s requirements and structural constraints (eg for buildings in historic centers).

 

Is it convenient to install a heat pump? Why?


A heat pump is convenient because:

  • It allows to halve the heating bills compared to a condensing boiler
  • It allows with only one unit to heat and cool
  • It enjoys incentives. Please verify your country rules
  • It uses renewable energies
  • It uses no fossil fuels and has no emissions from combustion
  • Thanks to a heat pump is not necessary to provide thermal solar 

How does a heat pump work?


Heat pumps can transfer energy present in nature to the buildings, heating them when it is cold and cooling them when it is hot. As well as a domestic refrigerator extracts heat from foods to keep them fresh, dispersing heat in the kitchen through the coil on the back, in the same way the heat pump draws energy to the ground, air or water by transferring it inside the environments as heat for winter heating and domestic hot water production. Ambient heat can come from different sources. The most used heat pumps are air-water, which collect heat from the outside air. There are also water-water heat pumps, which take heat from ground water. Finally, there are glycol water-water heat pumps, which remove heat from ground through underground tube collectors or geothermal probes.
A good heat pump, such as those proposed in Clivet integrated systems allows to get a lot of heat environment with few electricity: 1 kWh of electricity will produce up to 5 kWh of heating capacity.

What is the difference between the heat pump and the condensing boiler?


The difference between a condensing boiler and a heat pump lies in the way of the heat production: the boiler, at maximum, can provide the heat that the amount and the calorific value of the fuel allow. The heat pump, however, has not limits as to the energy inlet.
If there are suitable operating temperatures and fluids, the pump can carry indefinitely large amount of heat at constant used electricity.
A good heat pump allows to get a lot of heat with few electricity: from 1 kWh of electricity they produce up to 5 kWh of heating capacity.
The heat pump also does not use fossil fuel and does not emit combustion gases into the environment.
In addition to heat when it is cold, the heat pump can be used to cool indoor environments when it is hot.

How to choose the heat pump?


There are various types of heat pumps. To achieve maximum efficiency in terms of energy and cost savings, as well as to be sure of proper operation, it is necessary to choose the model best suited to your home according to several factors:

  • Type of building envelope
  • Climate
  • Size of the rooms to be air conditioned
  • Type of source that will be used by the heat pump (outside air, ground water, ground)

How to size the heat pump?


For the correct sizing of a heat pump it is necessary to consider different factors: insulation characteristics of the building, climatic zone, heated volumes, number of inhabitants and type of terminals (radiant panels, fan coils, radiators).
These assessments should be made on the advice of specialists such as the network Clivet Comfort A + Partner. Clivet also provides designers and installers with the tools useful for the selection, design and delivery of residential systems.

What capacity must have a heat pump for a flat?


To calculate the capacity of the heat pump for an apartment different factors must considered: insulation characteristics of the building, climatic zone, heated volumes, number of inhabitants and type of terminals (radiant panels, fan coils, radiators).
These assessments should be made on the advice of specialists such as the network Clivet Comfort A + Partner. Clivet also provides designers and installers with the tools useful for the selection, design and delivery of residential systems.
