Can your old heat pump make it through another winter?

Can your old heat pump make it through another winter?

Heat pumps are built to safely and reliably deliver heat and hot water year after year. But eventually the day comes when the heat pump has to be replaced.

The heat pump makes its greatest contribution in winter. But how do you know when it is time to replace it? The life span of a heat pump is about 15–20 years. They can go longer if they are not running at maximum. But there are also some questions to ask to determine if the pump is starting to fail.


Here are eight questions to find out if your heat pump is about to give out: 

  1. How old is the pump? 
  2. How often has it been running?
  3. Has electricity consumption increased recently?
  4. Does the immersion heater need to run more often? 
  5. Is the heat pump starting to show alarms? 
  6. Are there any other recent problems with the heating system?
  7. How do the elements and hot water work compared to before? 
  8. Does the heat pump sound different than before?

If you are not sure if your old heat pump is still up to standard, we recommend that you hire an installer for a service visit. They will look at your heat pump's performance and functions, and check whether everything is working in the best possible way.

.

Based on the visit, you can decide whether it is financially beneficial to continue servicing and repairing — or if it's time to replace your heat pump with a new, more efficient one.

Benefits of switching to a new heat pump

Don't forget to think long-term when making your decision. Are you going to make expansions? Are there plans to add to the family? These are important questions to consider.

How does the replacement actually work?

You can save both money and energy by investing in a new, modern solution. Today's heat pumps are more efficient and have smarter features than previous models.

If you've decided to utilise your existing borehole, installation is easy. Since the CTC GSi series, for example, has automatic borehole adaptation, you don't need to drill a new one.

In practice, you remove the old ground source heat pump and connect the new one.

If you have an air-to-water heat pump, it is usually just as easy to change, but sometimes it may be necessary to change the indoor module as well. If this is the case, your CTC installer will solve this.

Examples of replacement pumps

Speed-controlled and high efficiency, for example, make the CTC GSi ground source heat pump and the air/water heat pumps in the CTC EcoAir 600M and CTC EcoAir 700M series some of CTC's best heat pumps.

The new CTC GSi 608 is a state-of-the-art and high-performance ground source heat pump that automatically adapts to your existing borehole. The CTC GSi 8 is perfect for the smaller home when changing to a new heat pump.

CTC EcoAir 600M is a series of ultra-efficient, speed-controlled air-to-water heat pumps that automatically adapt to the heating needs of houses, properties or small industrial premises during the year. This means that you will always achieve maximum savings.

CTC EcoAir 700M is a range of variable speed air-to-water heat pumps with a stylish design and advanced technology that adapts to the needs of the house all year round. With environmentally friendly refrigerant and energy efficiency class A+++, these pumps offer both heating and cooling.
