CTC Ground Source Heat Pump: Efficient and Sustainable Heating

Did you know that the most reliable insurance against changing electricity prices is not found in exchange-rate contracts, but directly beneath your lawn? We understand the concerns that come with thinking about extensive earthworks and high initial investment, because no one wants to damage their garden or overpay for a system whose controls seem too complicated. It is only natural to want a solution that is both powerful and simple.

However, our team's experience shows that a correctly selected CTC ground source heat pump becomes the heart of the home, delivering peace of mind and warmth for at least the next 20 years thanks to smart EnergyFlex technology. This solution achieves outstanding energy efficiency with a SCOP above 5.0, which in practice means that for every kilowatt-hour of electricity consumed, you receive five times more heat completely free of charge.

Below, we will show why the quality created by Swedish engineers is so durable in Latvia's changeable weather. You will learn how the EnergyFlex system lets you add solar panels at any time and how current state support programmes, such as EKII or the Modernisation Fund, help make this smart investment more accessible for your family today.

What is a CTC ground source heat pump and why choose Swedish engineering?

When choosing a heating system, we often look for the golden mean between power and reliability. What is a ground source heat pump, and why is this technology becoming increasingly popular? In essence, it is a way to use the huge store of energy directly beneath our feet. Solar heat accumulates in groundwater and soil, and a CTC ground source heat pump efficiently converts it into home heating and domestic hot water.

Our choice in favour of the Swedish manufacturer CTC is no coincidence. With more than 100 years of engineering experience, this company understands northern climates better than almost anyone else. Its units are not simply adapted to cold; they are created to operate quietly and steadily even when a snowstorm is raging outside or temperature swings are sharp and unpredictable. It is like a reliable craftsperson who does the job flawlessly and without unnecessary noise.

One of the greatest advantages is the system's long service life. While other heating units begin to require serious repairs after ten years, a correctly installed CTC ground source heat pump can serve for as long as 25 to 30 years. It is a long-term investment that exceeds the resource of air-to-water systems, giving peace of mind to several generations.

How a ground source heat pump works in Latvia's climate

Latvia's nature has given us an excellent gift. Even in the harshest winter, the ground temperature at a depth of 1.2 to 1.5 metres remains stable, usually between +4 and +8 degrees. This constant inlet temperature is the main reason the system works so efficiently. Unlike air source heat pumps, a ground source unit does not need to spend extra energy fighting outdoor sub-zero temperatures, ensuring maximum output exactly when heat is needed most.

Why is ground source heating more cost-effective in the long term?

Although the initial works require careful planning, the benefits are undeniable. This heating method offers the lowest operating costs because the energy provided by nature is free. In addition, your home's facade remains untouched and aesthetic. There are no outdoor units creating noise for neighbours or vibration by the wall. Everything happens discreetly, underground or indoors, using a horizontal collector or boreholes, depending on the specifics of your plot.

CTC EnergyFlex and technological advantages

Imagine a heating system that grows together with your wishes and possibilities. CTC EnergyFlex is not just a technical feature; it is freedom of choice. Most heating units are closed systems to which it is difficult to add anything new. By contrast, a CTC ground source heat pump works as a smart energy hub. If today your priority is stable heat supply, but in a year's time you decide to install a wood boiler or solar collectors, EnergyFlex lets you connect them without expensive control unit replacement or complex programming.

When planning utilities, ground source heat pump installation is often considered the final step, but with CTC it is only the beginning. With the myUplink app, you are no longer just a passive observer. The system monitors electricity exchange prices and automatically adjusts its operation to heat the home when power is cheaper. This is especially important because CTC already uses next-generation refrigerants with low GWP. It means your unit will also comply with strict EU regulations after 2032.

How does EnergyFlex help you save?

The system's main strength is its ability to automatically choose the cheapest energy source at that moment. If the sun is shining outside, it will prioritise free energy from solar panel kits. This modularity means that a CTC ground source heat pump serves as a secure foundation into which you do not have to invest all funds at once. You can expand your engineering system gradually, knowing that the main unit is ready for it. If you want to find out how such a system would fit into your project, take a look at our borehole solutions, which ensure stable energy extraction.

Ground source heat pump installation: Collectors and boreholes

Once we understand the intelligence of the unit, it is time to focus on how the energy reaches your home. As the U.S. Department of Energy explains, geothermal systems are among the most efficient in the world because they use a stable ambient temperature. For a CTC ground source heat pump to operate at full output, the first step is choosing the right collector. It is like the foundation of a house; if it is poor quality, even the most expensive unit will not be able to show its potential.

Our team sees every day how important precise calculations are. If the collector is too short or the pipes are placed incorrectly, the ground can become overcooled in the spring months. This means the earth can no longer give off heat and the system's efficiency drops sharply. We provide a full cycle from design to technically precise implementation throughout Latvia, so your garden and heating system work in harmony.

Which type of collector should you choose?

The choice between a horizontal and vertical solution usually depends on the size of your plot and the existing landscape. A horizontal collector is a more economical solution if your property has at least 300 to 600 square metres of free area. The pipes are buried at a depth of approximately 1.2 to 1.5 metres, where the ground does not freeze.

By contrast, a vertical collector, or borehole, is ideal for small plots or places where the garden has already been landscaped and you do not want to dig it up. Boreholes provide an even more stable temperature because energy is taken from a greater depth. Learn more about how we carry out boreholes here to ensure maximum power per square metre.

Underfloor heating - the ideal partner for a CTC system

For a CTC ground source heat pump to achieve its highest SCOP rating, it works best with low-temperature heating systems. That is why underfloor heating is the best solution for both comfort and savings. It allows the heat carrier to operate at lower temperatures, which directly reduces your electricity bill. If you are planning new construction or a major renovation, we recommend choosing this combination for long-term benefit. Contact us to find the most suitable solution for your home layout.

Frequently asked questions about ground source heat pumps

How much does CTC ground source heat pump installation cost in Latvia?

The total installation cost is affected by several technical factors, such as the building's heat losses, the selected collector type and the scope of earthworks. Because every project is individual, the exact estimate is also influenced by soil composition and the required boreholes or length of the horizontal loop. To find out the precise costs for your home, we recommend carrying out a site survey, during which our specialists will prepare a detailed calculation according to your needs.

Can a ground source heat pump also cool the home in summer?

Yes, a ground source heat pump provides natural and very economical cooling during the summer months by using the stable temperature that remains deep in the soil. This process is called passive cooling, and it consumes significantly less electricity than conventional air conditioners. The system simply transfers excess heat from the rooms back into the ground, ensuring a pleasant microclimate without sharp temperature swings or draughts.

How much land area does a horizontal collector take up?

Installing a horizontal collector usually requires free land area that is approximately two to three times larger than the heated area of the house. For a medium-sized private home, this is usually 400 to 600 square metres of territory where no construction or large tree planting is planned directly above the pipes. If your plot is smaller, a vertical collector, or borehole, will be a more suitable choice, taking up only a very small area.

Can an existing wood boiler be connected to the CTC EnergyFlex system?

Yes, the unique concept of CTC EnergyFlex is created so that a CTC ground source heat pump can work in harmony with other heat sources, including wood boilers. It is an excellent way to keep the existing heating unit as a backup option or additional power for especially harsh winters. The system control unit automatically recognises the connected source and distributes heat efficiently, prioritising the cheapest available energy.

What state support is available for ground source heat pump installation in 2026?

In 2026, Latvian residents have access to state support through EKII and Modernisation Fund programmes, which help cover a significant share of equipment purchase costs. Especially favourable conditions are available to owners with "Goda ģimene" status, for whom the support intensity can reach up to 85% of eligible costs. The aim of these programmes is to promote the transition to renewable energy, so a CTC ground source heat pump becomes a financially even more accessible solution for many households.
