This year’s hot new feature in residential pumps is the new type of Daikin Altherma high-temperature pump, based on the latest double injection technology. With a leaving water temperature (LWT) of 70 °C at an outdoor temperature of -15 °C, this range is particularly suitable for use in renovating existing heating systems. The new-design heat pump unit, which won the prestigious iF and Red Dot Awards in 2019, is also very quiet.

The outdoor environment contains a huge amount of energy from the sun. It is energy in air, earth and water. A heat pump is a device that can obtain this environmental energy and then use it for heating or DHW heating.

Comfort and convenience are the characteristics of heat pumps. They require no refuelling and almost no maintenance. Their operation is fully automatic.

Remember that:

  • Each heat pump demand requires an individual assessment

  • It is worth it to think about the possibility of cooling the building in the warm season

  • The possibility of connecting the heat pump to other systems, such as solar water heating, should be considered

10 points to avoid mistakes when buying a heat pump

1. Never buy a separate heat pump. Always only as a full set with assembly, design and commissioning.

2. Arrange the delivery of the heat pump directly with an installation company, never order it through a construction company. If you pay the construction company for the heat pump and for some reason it does not pay the company what installed the heat pump, you will probably be without service and without warranty.

3. Throw offers of very cheap or ‘the cheapest heat pumps on the market’ immediately into the trash. When choosing a heat pump supplier, don’t just look at the lowest price.

4. Critically evaluate the promised guarantees and the company’s ability to meet the promised commitments.

5. Check the website of the heat pump supplier, importer or manufacturer on the Internet. Check that the information on parameters and warranties does not differ from what the seller claims.

6. Think about what you will do when a person who wants to sell you a heat pump is hit by a car. Is there enough experienced people in their company who will then provide you with service? Is there a representative for these heat pumps in the Czech Republic that will then take care of you?

7. Ask more companies, don’t be seduced by the first ‘favourable’ offer.

8. Take the time to inspect already installed heat pumps. See mainly:
– What the installation looks like after long-term operation
– Ask the owner what the warranty service was like
– Test how to control it
– Listen to how noisy the device is

9. Does the control communicate with you in your language? Check the quality of the instructions for use.

10. Get advice only from people who have a heat pump and know what they are talking about.
