How does a ground-to-water heat pump work?
A ground-to-water heat pump is a geothermal heating solution that uses the stable heat stored in the earth and converts it into energy for building heating, passive or active cooling in summer, and domestic hot water production. Since ground temperature remains constant at deeper layers throughout the year, this system delivers maximum efficiency even during the harshest winter frosts.
What should you focus on first when buying a geothermal heat pump in Lithuania?
Purchasing a geothermal heat pump doesn’t start with choosing a brand, but with analyzing the building’s needs and the plot’s possibilities. To achieve a truly efficient solution, it’s essential to accurately assess the building’s heat losses, the type of existing or planned heating system, hot water consumption habits, and the type of geothermal loop.
The technical data for “IGLU Aleut” offers a wide power range from 4 to 18 kW, allowing the unit to be perfectly matched to a specific property. The manufacturer states a seasonal efficiency coefficient (SCOP) of up to 5.79 for low‑temperature heating (B0/W35). This figure is more important than the instantaneous COP because it shows the actual average efficiency over the entire heating season and allows for a more accurate forecast of future electricity costs.
If your home has underfloor heating, the system will operate in its most economical mode. If the building still has radiators, you need to check the unit’s efficiency at higher supply water temperatures. Since the “IGLU Aleut Inverter” models have a maximum supply temperature of up to 65 °C, they handle radiator heating tasks successfully and ensure sufficient temperature for domestic hot water production without the help of additional electric heaters.
Why is variable-capacity (inverter) technology superior?
Modern “IGLU Aleut” models use advanced inverter technology that automatically adjusts compressor speed and matches the heating or cooling output to the building’s real-time demand.
Unlike older fixed-capacity pumps that constantly switch on and off while running at full power, an inverter heat pump operates smoothly. During transitional seasons (spring or autumn), when the house needs very little heat, the compressor reduces its speed to a minimum. This avoids energy waste, extends compressor service life, and delivers noticeably higher annual efficiency. For the buyer, this means lower operating costs and a more stable indoor climate.
What does the IGLU Home Next platform and remote monitoring offer the user?
Smart control in a modern heating device isn’t for entertainment—it’s for practical energy management and proactive maintenance. The IGLU Home Next app lets you bring your home’s entire energy ecosystem together in one place.
Through this free app, the user can not only conveniently set the desired room or hot water temperature and adjust heating schedules, but also monitor system operation in real time: electricity consumption, produced heat, and instant efficiency indicators.
Even more importantly, IGLU TECH applies a remote monitoring and 24/7 diagnostics model to its devices. By connecting the heat pump to the manufacturer’s server, the technical support team can view system parameters remotely, detect deviations or errors, and in many cases resolve them before the user even notices a temperature change at home. This remote connection is one of the main conditions for obtaining an extended manufacturer’s warranty of up to 60 months.
When is it worth choosing geothermal heating, and when should you look for other alternatives?
A ground-to-water heat pump is an ideal choice if you are building or renovating a long-term home, aiming for the highest possible energy independence, and want a single system that reliably heats in winter and cools your home very cheaply in summer (using passive cooling from the ground).
However, this solution requires certain conditions:
- Plot possibilities: Horizontaliam kolektojui reikalingas pakankamas laisvos žemės plotas, kuriame negalima sodinti giliašaknių medžių ar statyti statinių. Jei vietos mažai, vienintelis kelias – vertikalus gręžinys, kuris padidina pradinę projekto sąmatą.
- Budget: Geoterminio šildymo pradinė investicija yra didesnė nei oras-vanduo sistemų dėl reikalingų žemės darbų ar gręžimo. Jei jūsų biudžetas griežtai ribotas arba pastate planuojate gyventi tik trumpą laiką, verta racionaliai apskaičiuoti atsiperkamumo laikotarpį ir pasidomėti „IGLU Inuit“ oro-vandens sistemų alternatyvomis.
- Room preparation: Pagal techninius reikalavimus įrenginį rekomenduojama montuoti ant lygaus, tvirto pagrindo patalpoje, kurioje palaikoma teigiama temperatūra (nuo +10 iki +35 °C) ir yra įrengtas drenažo mazgas kondensato ar sistemos išleidimo atveju.
How to assess state support and what does it change for the buyer?
State financial support can significantly reduce the initial cost of installing a geothermal heating system in Lithuania. The funding is administered by the Lithuanian Energy Agency (LEA), and calls for support are announced periodically.
The amount of compensation usually depends on the type of old inefficient boiler being replaced or the parameters of the new unit being installed, and the highest subsidies are traditionally granted specifically for geothermal heating, as it is one of the most environmentally friendly technologies. Since IGLU Aleut units fully meet and exceed the requirements set by the state, buyers can confidently submit applications for funding. The most important thing is to submit the application on time, before the official call deadline ends, and wait for the agency’s approval before starting the dismantling of the old boiler.

Frequently Asked Questions
Is “IGLU Aleut” only suitable for newly built homes?
No, these heat pumps are also an excellent fit for renovated buildings. Thanks to their ability to produce water up to 65 °C, they can be successfully integrated into older radiator-based systems, though maximum efficiency is always achieved with underfloor heating.
What are the advantages of the WTI model with an integrated tank?
WTI models already include a built-in 180-liter stainless steel boiler for domestic hot water preparation. This saves a lot of space in the boiler room, simplifies and speeds up installation work, and ensures an aesthetic, seamless look.
Is it possible to see exactly how much electricity the pump consumes?
Yes. With the IGLU Home Next app, you can monitor actual electricity consumption, the amount of heat produced, and view detailed statistics by day, week, or month.
Can a geothermal heat pump cool the home in summer?
Yes, IGLU Aleut has a passive cooling function. In summer, coolness from deep underground is delivered to the home through underfloor heating or wall cooling systems. This is a highly economical way to maintain comfort, using minimal electricity.
Where do people most often make mistakes when choosing geothermal heating?
The biggest mistake is to choose the unit’s capacity by eye or compare only the heat pump’s price online. You must evaluate the cost of the entire project, including the installation of the outdoor loop (boreholes or collector), system commissioning and tuning, as well as the warranty service model.
