What is a ground-to-water heat pump for?
A ground-to-water heat pump is a geothermal heating device that extracts heat from the ground and transfers it for building heating, cooling, and domestic hot water preparation.
How does the IGLU Aleut Inverter work in a home?
In practice, the IGLU Aleut Inverter serves as the main device for a building’s heating, cooling, and domestic hot water system—it uses a geothermal loop, modulates output according to demand, and can produce hot water. The user manual clearly states that the Aleut is intended for heating, hot water, and cooling, while the technical data coding additionally provides for active and passive cooling options in certain configurations.
In everyday operation, this means much more than simple “on or off” logic. Inverter models run at varying compressor speeds, allowing the heating output to match actual demand. For example, in the technical data for AL 12 I N under the B0/W35 mode, several operating points are listed from 2.70 kW to 11.61 kW, depending on compressor speed. Such modulation is important because the system doesn’t need to run at maximum all the time.
IGLU Home Next app lets you see electricity consumption, generated thermal energy, COP, and statistics in real time by day, week, month, or year. This data helps not only to track costs but also to understand how the system performs across seasons—whether efficiency drops in the coldest months and whether the loop is properly designed. If you’re planning a broader home energy management solutions installation, this feature becomes an important part of the system.
On the other hand, the device’s features alone are not enough. You need a correctly selected ground loop, a proper installation location, and a well-balanced heating system.
Is the IGLU Aleut Inverter only suitable for newly built homes?
IGLU Aleut Inverter is suitable not only for new construction but also for some renovated properties, provided their heating system and heat demand allow for a geothermal solution. The current IGLU Aleut Inverter family page states that this series is suitable for both new builds and renovated homes, with a recommended area of 80–350 m².
In the case of a new house, the situation is simpler, because you can plan the boreholes or horizontal loop, the boiler room location, underfloor heating, and domestic hot water in advance. In such a case, the geothermal heat pump usually operates at its strongest. According to technical data, inverter models reach an SCOP of 5.6–5.95 for underfloor heating in a temperate climate, and 3.98–4.44 for radiator heating. This difference clearly shows that a lower-temperature system is more favorable for geothermal.
In a house undergoing renovation, the key question isn’t just “can it be connected,” but also “what water temperature does the system need.” Aleut delivers up to 65 °C at most, which is sufficient for part of radiator systems, but in older, less insulated homes, simply replacing the pump may not deliver the desired result without additional work. Here it’s also worth looking into heat pump selection consultation and options for improving the home’s energy efficiency.
Geothermal isn’t automatically a solution only for new A++ homes, but renovation requires more calculation and less guesswork.
How does IGLU Aleut Inverter differ from other alternatives?
IGLU Aleut Inverter differs from fixed-capacity models primarily in that it can adjust compressor operation to actual demand rather than running in just a few constant modes. This is very clear in the technical data tables— inverter models are shown with multiple compressor speeds, while fixed-capacity models have a single nominal operating profile.
This matters for comfort, duty cycles, and how the system adapts to shoulder seasons. The sound power level of the inverter AL 07 I, AL 12 I, and AL 18 I models is listed at 39 dBA, while some fixed-capacity models reach 42 dBA, and the 16 kW model 45 dBA according to IGLU technical data. The difference may not look huge on paper, but in a boiler room or near living spaces it can be noticeable.
Compared to air-to-water solutions, a geothermal heat pump is generally appreciated for having a more stable source. Ground temperature fluctuates less than outdoor air, so the efficiency curve is typically smoother. Buyers should compare not only the unit’s price, but also seasonality, noise, the absence of an outdoor unit, and the cost of installing the loop.
A common mistake buyers make is to compare only one figure, most often the COP. If you’re choosing between solutions, it’s better to look side by side at SCOP, the 65 °C limit, app features, the need for an integrated 180 l tank, and site readiness. IGLU Aleut Inverter shines most when the entire usage scenario is evaluated, not just the first-day offer price.
Why does IGLU TECH stand out?
The IGLU Aleut Inverter series has several specific technical differences that allow it to be evaluated separately from typical market offerings.
The sound power level of the inverter AL 07 I, AL 12 I, and AL 18 I models reaches 39 dBA. Compared to fixed-capacity series rated at 42–45 dBA, that’s a real difference in a boiler room or utility room near living spaces. On the AL 12 I product page, COP is listed as 4.75 and SCOP as 5.75 at 35°C. With modulating output—for example, the AL 12 I operates from 2.70 kW to 11.61 kW—the system adapts to the season, avoiding overheating rooms and unnecessary cycling.
IGLU Home Next app here it becomes not an add-on but a diagnostic tool. Daily, weekly, and monthly COP and energy statistics let you check over the season whether the system is operating as designed. If the ground loop is too weak or the heating system doesn’t meet demand, the app will show it in numbers rather than a fault signal.
Who this solution is NOT for
IGLU Aleut Inverter is not suitable in all situations. A few specific cases when it’s worth considering other alternatives:
- Geothermal boreholes are impossible or prohibitively expensive. If the plot conditions, soil structure, or budget do not allow for installing a sufficient ground loop, the unit itself will not deliver optimal efficiency.
- The house has high heat loss with no renovation plan. If the building is very leaky and no improvement in thermal insulation is planned, geothermal can work, but it will not deliver the expected economic benefit.
- Need a quick solution without design work? A geothermal heat pump requires site analysis, loop design, and professional installation. It’s not a “buy – plug in – it works” category.
FAQ
Can the IGLU Aleut Inverter produce hot water and cool rooms?
Yes, the Aleut line is designed for heating, domestic hot water production, and cooling. This is stated directly in the user manual, and some model pages indicate both passive and active cooling.
Is the inverter model really quieter than the fixed-capacity version?
According to IGLU technical data, the sound power level of inverter models is 39 dBA, while for some fixed-power models it reaches 42–45 dBA. This isn’t the only criterion, but it matters for the installation location.
Does a ground-to-water heat pump suit radiators?
It may fit, as Aleut supplies up to 65 °C at maximum. However, actual suitability depends on the home’s heat losses and the existing radiator system, so a site assessment is necessary before purchase.
Can the system be controlled by phone?
Taip, Aleut valdomas per IGLU Home Next app. The app lets you monitor parameters, energy consumption, heat production, and errors.
Is it possible to receive state support?
Yes, but only if the specific project and equipment meet the conditions of the LEA call in effect at that time. Heat pumps as a category may be eligible, but the compliance of a specific IGLU model must be checked against the current conditions.
What should you compare first before buying?
First, don’t just compare COP or the unit’s power. It’s much more important to compare SCOP, the loop/contour solution, the domestic hot water package, the maximum supply temperature, noise, warranty terms, and the scope of installation.
What should you do next?
If you’re considering whether IGLU Aleut Inverter is right for your home, the most logical next step isn’t to guess based on general forum comments, but to assess the specific property. Request a heat demand calculation, an analysis of the loop’s capabilities, and a clear proposal that shows the entire system. If you want to make a decision faster, it’s worth applying for geothermal heating consultation or simply discuss the project via contact page.
