The heat pump as the modern heating standard: What is it?

The heating sector has changed dramatically in recent years. In 2026, a heat pump is no longer discussed as an exotic technology of the future; it has become the principal standard for every energy-efficient home in Latvia. The Commodus team has been helping households choose the most suitable solutions for more than 15 years. During this time, we have learned that working alongside the customer means more than merely installing equipment; it also means providing a sense of security and technical support for decades. Our experience shows that switching to renewable energy is the only logical way to avoid unpredictable fluctuations in fossil-fuel prices.

In essence, What is a heat pump? It is an intelligent engineering device that does not generate heat by burning resources, but instead efficiently transfers energy from the environment — air, ground or water — into your home's heating system. Compared with natural gas or pellets, a heat pump can produce up to five times more heat energy for every kilowatt of electricity consumed. This is possible because the laws of thermodynamics allow energy to be extracted even when outdoor temperatures are below zero.

By 2026, European Union regulations and carbon-emission taxation requirements have made fossil fuels an economically unattractive choice. The installation of new gas boilers is being restricted in many places, which is why a heat pump has become the primary choice for both new builds and renovation projects. It is not merely a method of heating; it is an investment in independence from imported resources and global market disruptions.

The most popular types of heat pump in Latvia

When choosing the most suitable system, it is important to understand the characteristics of the local climate. Three solutions are used most often in Latvia:

• Air-to-water: This is the most versatile option and is selected by approximately 72% of our customers. It is relatively easy to install and provides both space heating and domestic hot water using energy from the outdoor air.
• Air-to-air: Ideal as an additional heat source or for smaller spaces. The system works much like an air conditioner, providing heat in winter and efficient cooling in summer.
• Ground-source heat pumps: Although the initial investment is higher because earthworks are required, this system provides the highest coefficient of performance (COP), even at temperatures of -30°C.

Why is a heat pump a 'smart' investment?

Installing a heat pump increases the market value of a property by an average of 12%. It is a long-term investment, as a high-quality unit can last 20 or even 25 years. You no longer need to plan fuel purchases at the beginning of the season or clean chimneys; the system operates fully automatically. Modern units also offer passive cooling during the summer months, providing year-round comfort without the need to install additional air conditioners. Reducing CO2 emissions ensures compliance with current EU directives and protects you against possible future taxes on environmentally harmful heating.

Efficiency during a Latvian winter: Does it really provide enough heat?

Many Latvian homeowners still believe the myth that an air-to-water heat pump becomes an expensive decorative item when the temperature falls to -25°C. That is not true. Technology has advanced significantly, and 2026 models operate reliably even in severe frost, providing comfort without unnecessary stress. The main figure to consider is SCOP. COP indicates efficiency at a specific operating point, while SCOP shows the average performance over an entire season. The International Energy Agency report confirms that heat pumps are the most energy-efficient solution even in colder regions because they can produce three to five times more heat than the electricity they consume.

Inverter technology works in a similar way to cruise control in a car. Instead of repeatedly switching on and off at full capacity, the heat pump adapts and operates steadily. This not only protects the equipment but also helps maintain a stable indoor temperature without fluctuations. However, even the best unit will be ineffective if it is selected incorrectly. Professional system design is more important than the unit itself, because an error in capacity calculations can lead to excessive bills or insufficient heating.

Monobloc versus split system: Which should you choose?

The main advantage of a monobloc unit is simpler installation. The entire system is housed in a single outdoor casing, so no refrigerant work is required indoors. It is an excellent solution when indoor space is limited. A split system, by contrast, is more efficient when there is a greater distance between the units because heat losses through the pipework are minimal. The choice often depends on the house layout and the space available on the ground or wall.

Thermal inertia and defrost cycles

When the weather is cold and damp, frost can form on the outdoor unit. The heat pump resolves this with an automatic defrost cycle that temporarily reverses its operation. At this point, the thermal inertia of the system is important so that the indoor temperature does not fall. The bivalence point is a safety margin in system capacity, defining the outdoor temperature at which an additional heating element begins assisting the heat pump. To find out which solution would suit your home, try our heating calculator, which will help you assess the required capacity.

• SCOP value: The higher it is, the lower your electricity bill will be over the heating season.
• Low temperatures: High-quality units retain their heating capacity even at -25°C.
• Design: A correctly selected bivalence point prevents excessive system consumption.

The major comparison: Heat pumps versus other heating systems

When selecting a heating system, people often ask whether a modern heat pump genuinely outperforms established solutions such as pellet boilers or wood heating. In practice, the greatest difference lies in comfort and cleanliness. A pellet-boiler owner spends an average of 30 to 50 hours a year cleaning ash, servicing the burner and adding fuel. A heat pump operates completely autonomously, requires no physical intervention and keeps the plant room clean.

The economic benefit becomes clear when calculating the cost of each kWh of heat produced. Pellet-heating costs fluctuate with seasonal prices, whereas with a heat pump achieving an average SCOP of 4.0, every unit of electricity consumed produces four units of heat. Heat pump operating principles confirm that this technology does not generate heat from nothing, but efficiently transfers energy from the environment, making it a leader in efficiency. Under Latvian conditions, the investment usually pays back within six to eight years when state-support programmes are used.

• Heat pump: 0 hours of monthly maintenance, high cleanliness and complete automation.
• Pellet boiler: regular cleaning, a fuel-storage area and ash disposal are required.
• Compatibility: modern heat pumps operate efficiently with both underfloor heating at 35°C and radiators at up to 65°C.

Heat pumps and solar panels: The ideal combination

This combination represents the highest level of energy independence. Under the net settlement system, electricity generated in summer can be 'stored' in the grid and used for heating during the winter months. Smart controls allow the system to raise the indoor temperature automatically by a few degrees precisely when the solar panels are generating maximum power. This turns the structure of your home into a type of thermal battery and reduces heating bills to a minimum. Our experience shows that this synergy is the fastest-growing solution in new-build projects.

Modernising an existing heating system

Many people fear that a heat pump will not work with old cast-iron radiators. In reality, high-temperature heat pumps have been designed specifically for such situations. If the building insulation is still insufficient, a hybrid system is an excellent solution. You retain the existing wood or gas boiler as a backup for exceptionally cold winter nights while benefiting from heat-pump efficiency for 90% of the time. This approach not only improves comfort but also provides reassurance that the home will always remain warm regardless of weather conditions or energy prices. At Commodus, we work alongside you to find the technically correct solution for your building.

Planning, installation and state support in 2026

An efficient heating system begins not in a shop, but at the drawing board or during the first consultation. In 2026, building energy-efficiency requirements have become even stricter, making accurate planning essential. The process normally takes four to eight weeks. It begins with a heat-loss calculation for the house and ends with the first sensation of warm flooring beneath your feet. At Commodus, we believe that the customer should feel secure at every stage, which is why we provide the complete cycle from system design to commissioning.

Before installation begins, the available electrical capacity must be checked. A modern heat pump usually requires a three-phase electrical supply. For a unit with a capacity of up to 10 kW, 16 A or 20 A circuit protection will be sufficient in most cases. However, if an electric vehicle charger and an induction hob will operate at the same time, an electrical-capacity audit should be carried out before purchasing the unit. This prevents unpleasant surprises when the first frost arrives and the system begins operating at full capacity.

How can you obtain state support for a heat pump?

In 2026, Altum and EKII support programmes aimed at replacing fossil-fuel boilers remain available. Depending on the conditions of the selected programme, support may cover as much as 50% or 70% of eligible costs. The main criteria are that the building has been commissioned and that the new heat pump provides a high seasonal coefficient of performance (SCOP). Paperwork often appears complicated, but we effectively carry the burden for you. Commodus specialists help prepare all necessary reports and applications so that obtaining funding is as straightforward as possible.

Technical details of heat pump installation

When installing an air-to-water system, the most important consideration is the location of the outdoor unit. It must be positioned where airflow is unrestricted and the noise will not disturb either the occupants or neighbours. Models for 2026 are quieter, but vibration isolation remains essential. If a ground-source heat pump is selected, drilling boreholes must be taken into account. Under Latvian geological conditions, a single borehole usually reaches a depth of approximately 100 metres, providing a stable temperature throughout the year.

• Check that the installer is certified to work with refrigerants and F-gases.
• Ask how often warranty maintenance is required and what remote-control options are available.
• Make sure the installation quotation includes all materials, not only the unit itself.

Completing the documentation does not end when the invoice is paid. The system must be commissioned and the changes registered in the Construction Information System (BIS). This is important not only for receiving state support but also for home insurance and future resale value. Our experience shows that correct paperwork saves more money in the long term than the cheapest installation offer on the market.

Frequently asked questions about heat pumps

Can a heat pump fully replace wood or pellet heating?

Yes. A modern heat pump can fully replace a solid-fuel boiler and provide autonomous heating even at -25°C. You no longer need to arrange firewood supplies or clean ash every day, because the system operates automatically and maintains an even temperature throughout the home. Our experience shows that 95% of customers switching from pellets value the time savings and cleanliness of the house most highly.

How noisy is a heat pump outdoor unit, and will it disturb the neighbours?

The noise level of modern units measured at a distance of three metres usually does not exceed 35 to 45 decibels, which is comparable to a quiet whisper or a refrigerator. If the correct distance from neighbouring windows is observed and high-quality anti-vibration mounts are used, the noise will not disturb anyone. We will help identify the optimum position beside the house so that both you and nearby residents can enjoy peace and quiet.

What are the average annual heat pump maintenance costs?

Standard maintenance should be carried out once a year to preserve the manufacturer's warranty and ensure maximum system efficiency. A specialist checks the refrigerant pressure, cleans the heat exchangers and verifies the operation of the electronics, which usually takes approximately one to two hours. Timely inspection of the heat pump reduces risks and helps maintain a high COP, which directly affects the size of your winter electricity bills.

Does a heat pump require a three-phase electrical connection?

Most units with a capacity above 6 or 8 kW require a three-phase connection so that the load is distributed evenly across the phases. A single-phase supply may be sufficient for smaller homes, but this must always be checked against the property's total electrical capacity. Before installation, we inspect the parameters of your existing connection to ensure that the system operates reliably and does not trip the circuit breakers when you switch on the kettle.

How long does a heat pump usually take to pay for itself?

The average payback period is five to ten years, depending on the selected model and the efficiency of the previous heating system. When state-support programmes are used, this period may be reduced by 30% or even 50%. A heat pump is a long-term investment in comfort that increases the market value of the property immediately after installation and commissioning.

Can I install a heat pump myself to save money?

Self-installation is not recommended and may be unlawful because work involving refrigerants requires a special certificate. If installation is not performed by a certified specialist, the manufacturer's warranty is immediately invalidated, which can result in substantial losses if technical faults arise. Our team carries out this work every day, so professional heat-pump installation takes only one to two days and ensures safe operation for years.

Which heat pump is most suitable for an older renovated house?

A high-temperature air-to-water heat pump is generally the best choice for a renovated building because it can heat radiator water to 65°C or even 75°C. If the house has been insulated properly, the system will operate even more efficiently and consume less electricity. It is essential to calculate heat losses accurately after the renovation has been completed so that the selected capacity matches the building's new energy performance and the radiator area.

Is state support also available for air-to-air heat pumps?

Under current support programmes such as Altum or EKII projects, air-to-air systems are usually not subsidised because the emphasis is placed on water-based central heating. State support is mainly intended for the installation of air-to-water or ground-source heat pumps to replace old fossil-fuel boilers. Nevertheless, every heat pump is a valuable investment, and we will help prepare all necessary documents for an application under the relevant programme.
