How efficient are heat pumps?

What you need to know about heat pumps before buying it.


With energy bills being a major item of a household's expenditure, more and more people are looking for the most economical options that also have the least possible impact on the environment. Heat pumps do not burn fossil fuels and are therefore considered an eco-friendly option for entire heating houses. They are also proven to be highly energy efficient.


If you're looking for a way to reduce your cooling and heating costs while helping to minimize environmental damage, this may be your solution.


How does a heat pump work?

A heat pump is a system that works well in both cooling and heating modes. The reason for its energy efficiency is that it uses already available water and air resources to operate.


The heat pump is installed outside the home and uses the heat of the available resources, heating or cooling them through a refrigerant, depending on the household's needs.



A standard heat pump consists of several parts:

Outdoor unit: It houses the evaporator coil, which evaporates in heating mode or condenses in cooling mode.

Indoor unit: It houses the coil and fan that circulates the air in the home.

Refrigerant: It helps absorb and release heat into the system so it can run efficiently.

Compressor: Thanks to this important component, the pressure increases and the refrigerant is prepared for the next processes in the system.

Reversing valve: This regulates the movement of the refrigerant so that you can choose whether the system operates in cooling or heating mode.


If used and maintained properly, a heat pump can save you approximately 50% on electricity costs compared to heating systems such as electric radiators and stoves.


Advantages and disadvantages of air-to-water heat pumps

Air-to-water heat pumps are a great choice for distributing heating and hot water throughout your house with minimal impact on the environment. To help you make an informed decision about whether this is the right choice for you, let's take a look at the pros and cons of air-source heat pumps.



  • Suitable for new construction as well as retrofits.
  • Compact and relatively small in size.
  • Suitable for heating and cooling a house and large apartment.
  • Adds value to your home. If you decide to sell or rent it, you can list a higher price.
  • Safe operation technology.
  • Since air conditioning is done by processing the air from the outside environment, it is a very eco-friendly option.
  • The technology allows much more energy to be generated than is used.
  • There is no residual dirt and smoke, unlike wood stoves.
  • Easy maintenance.




  • Significant initial investment.
  • Pre-planning of installation.
  • To be effective, you must have other fixtures installed such as underfloor heating and radiators through which to circulate hot water.
  • Efficiency depends on good quality house insulation.
  • You may have to pay for additional work such as installing new radiators.
  • They are not as effective in extreme cold temperatures.


How efficient are air-to-water heat pumps?

Using an air-to-water heat pump reduces your carbon footprint by 50%. This is because, although it runs on electricity, it uses mostly renewable green energy. It processes the outside air, which is then transferred into the system and generates optimal heating and hot water for your home.


Maintenance and care of the air-to-water heat pump

  • To serve you long and as efficiently as possible, this system still requires basic care on your part. Let's also note what they are:
  • Keep the outdoor unit cleaned.
  • Clean the outdoor unit filter regularly.
  • Keep the system dry and the area around it well cleaned to allow airflow to move unimpeded.
  • Check the water quality in the tank and descale if necessary.
  • Check the system for leaks.
  • Be sure to schedule a maintenance check by a professional in the spring and winter.


More and more people are talking about the footprint humans leave on the environment. It is good to think about how we as consumers can reduce it. Heat pumps are efficient systems that can help reduce the use of fossil fuels for heating. If you maintain your system properly, you can count on it to serve you for a long time, and its cost will pay for itself many times over.
