Myths about heat pumps
Unfortunately there are some very stubborn prejudices and assumptions relating to heat pumps – yet they quickly turn out to be a load of hot air when examined more closely.
Heat pumps are some of the most innovative and sustainable solutions for heating and cooling buildings. However, there are numerous myths and misunderstandings around them, meaning that potential users often hesitate to use this technology. In this article, we will expose some of the most common myths about heat pumps and present the facts which provide a clearer understanding of these environmentally friendly heating and cooling systems. Let's take a look at these myths together and uncover the truth about heat pumps.
Common myths refuted in the fact check
Unfortunately there are some very stubborn prejudices and assumptions relating to heat pumps – yet they quickly turn out to be a load of hot air when examined more closely. Let's take a look at some of the most common ones here:
"Heat pumps are so loud that the neighbors will complain!"
Fact check
A heat pump operating outdoors is extremely quiet. For example, if you look at the ESTIA outdoor unit, the sound pressure level is just 30 dB(A) – even from a distance of just a few meters. As a comparison, this volume corresponds to people whispering or the inside of a library.
"Heat pumps can't properly warm you up when it's cold outside!"
Fact check
Even if the ambient temperature falls to -25 degree Celsius, a heat pump is still able to ensure seamless heating operation and cozy warmth in your own four walls thanks to intelligent compressor technology. Roll on winter!
"After my partner has got out of the shower, there will only be cold water left for me!"
Fact check
The flow rate of a conventional shower head is around 12 liters of water per minute. Therefore, if you let the water run uninterrupted for 10 minutes, you need approx. 120 liters of water. Water tanks are usually set to temperatures much higher than is comfortable for showering, meaning that only a portion of the water from the boiler is required. State-of-the-art heating systems provide tanks with various dimensions. Simply choose the larger model if needed so that you have enough hot water for the entire family.
"Heat pumps use so much power – you may as well install electric heating!"
Fact check
The ratio of electrical energy to energy from the air is around 4:1 when heating using the ESTIA air-to-water heat pump. This means that the majority of the heat is recovered directly from the air and a small proportion of electric power is required to operate the pump. However, it is the case that power consumption increases if the rooms are heated using radiators with a small surface area, as the supply water temperature to the heat pump has to be brought to a higher level in this case, which in turn is reflected in increased power consumption. In this case, installing underfloor heating is advisable.
