Six misconceptions about heat pumps

One topic is currently of particular concern to homeowners and those who aspire to be: the energy transition in the heating sector and what needs to be done or can be done to achieve it. Especially when it comes to heating, people are looking for more energy- and cost-efficient methods. Heat pumps are leading the way. However, in researching this topic, you'll repeatedly encounter statements that we'll debunk for you as myths.

1. No one can afford the investment costs

Unlike a gas heating system, the initial purchase price of a heat pump is indeed several thousand euros higher. However, you should bear in mind that the installation is subsidized by the government with low-interest loans. And it's worth thinking long-term, because in terms of operating costs, a heat pump is no more expensive than a gas heating system.

2. The ongoing costs are too high

A heat pump requires electricity to operate, as it generates heat by converting air. But don't worry: it works extremely efficiently, quadrupling the energy input. The only energy-consuming component is the heating element. This, in turn, only needs to be activated on very cold days. Furthermore, if the necessary energy is generated by on-site photovoltaics, you're essentially killing two birds with one stone.

3. A heat pump is too loud

It's often said that heat pumps generate noise that disturbs both you and your neighbors' sleep. In reality, they're about as loud as a refrigerator. To maintain good relations with your neighbors, a distance of three meters should be maintained if the fan is pointing towards the property line.

If you are in the process of buying a new property and are unsure what else you need to consider when installing a heat pump, ask your real estate agent. They can advise you on the topic or recommend an energy consultant.

4. A heat pump is not as environmentally friendly as you might think

If the energy used by the heat pump is renewable, there are no CO2 emissions. A common criticism is that a heat pump requires refrigerant to generate heat. However, in this case, harmless R290 propane is used, which does not damage the ozone layer.

5. A heat pump only works with an oil and gas heating system

The idea that heat pumps can't heat a building on their own is a myth. While the system is known to work best in conjunction with underfloor heating, don't worry: regular radiators also work perfectly well with a heat pump.

6. When it gets really cold, the heat pump no longer works

Perfectly adequate for winter use at home: air source heat pumps operate reliably down to -20 degrees Celsius. A constant heat supply is also guaranteed, as all available models have an additional heating element. This element is not activated automatically, but it requires minimal effort: the user simply presses a button.
