Today, for many homeowners in Lithuania, an air-to-water heat pump is one of the most realistic ways to cut heating costs and replace an old boiler. If you’re looking not only for the unit itself but also for a clear choice among different capacities, configurations, and control options, it’s worth focusing on a manufacturer that provides comprehensive technical data and clearly shows what each specific model is suited for. In this article, we’ll explain what it practically means to choose IGLU TECH and how it differs IGLU Inuit Split bei IGLU Inuit Mono series when you’re looking for a heating solution for a home in Lithuania.
Key takeaways
- An air-to-water heat pump is best suited for homes that need heating, cooling, and domestic hot water from a single unit.
- For the buyer, the most important factors aren’t just capacity, but also operating temperatures, COP under different conditions, and the method of domestic hot water preparation.
- If your home needs higher water temperatures, it’s worth considering the IGLU Inuit Mono series.
- A model with an integrated tank is most beneficial when you want a more compact and simpler domestic hot water solution.
- The main difference is that not every air-to-water heat pump works equally well at a 55 °C supply temperature.

How do IGLU Inuit Split and IGLU Inuit Mono differ?
Renkantis tarp IGLU Inuit Split and IGLU Inuit Mono you need to decide what water temperature, what installation type, and what domestic hot water preparation method you need. Both series are intended for heating, cooling, and domestic hot water, but their technical solutions differ.
IGLU Inuit Split the series is offered in 6, 9, 12, and 16 kW capacities, and IGLU Inuit Mono series is offered in 5, 8, 12, and 16 kW capacities. If you’re considering a renovated or newer home with underfloor heating, it’s relevant that the IGLU Inuit Mono models have SCOPs at 35 °C of 5.10, 4.85, 4.90, and 4.70, with an A+++ rating. This shows the series is well suited to low-temperature systems where seasonal efficiency matters.
Another important difference is the supply temperature. The maximum flow temperature of the IGLU Inuit series reaches 65 °C, while the IGLU Inuit Mono series goes up to 75 °C. The user manual also clearly states that in IGLU Inuit models, hot water from 54 °C to 65 °C is prepared using an auxiliary heater, whereas the IGLU Inuit Mono compressor can heat water up to 65 °C without an additional heating element.
If simpler hot water preparation at a higher temperature is important to you, the Mono series may be the more logical choice. If a classic Split-type configuration and a clear power range are more important, it’s worth looking at the IGLU Inuit Split.
Is the WT model with an integrated tank better suited for a family home?
A WT model with an integrated tank is often better for a family home when you want a single indoor unit to contain both the heating module and the domestic hot water tank. This solution usually helps reduce the number of separate components in the boiler room.
IGLU Inuit Split WTI models have a 200-liter domestic hot water tank made of AISI 444 stainless steel, while IGLU Inuit Mono WT models have a 180-liter tank made of the same material. In practice, this means a family does not need to arrange an additional tank separately if the WT option matches their consumption habits.
Another practical criterion is space. The dimensions of the IGLU Inuit WT indoor unit are specified as 600x1773x676 mm, while the IGLU Inuit Mono WT is 598x1880x673 mm. The difference isn’t large, but in a small utility room a few centimeters or the service clearance can matter. If you’re also considering a heat pump for a home with an integrated tank, it’s worth evaluating not only the number of liters but also where the equipment will stand.
Still, WT is not always the best option. If you already have a good separate boiler at home or are planning a non-standard domestic hot water setup, the classic model without an integrated tank can be more flexible. This helps the buyer understand that choosing WT pays off most when you want the simplest, most compact, and pre-configured system.
How to assess performance in Lithuanian winters, not just COP?
Performance in Lithuanian winters should be assessed under several temperature conditions, not just by one nice COP figure at +7 °C. This is where technical data tables are more useful than general promises. For example, the nominal heating capacity and COP of the IGLU Inuit 6 model at O7/V35 are 6.0 kW and 4.92, but at O-7/V35 they are 5.5 kW and 2.75. The IGLU Inuit 12 at O7/V35 has 12.0 kW and 4.63, and at O-7/V35 11.77 kW and 2.41. These figures are taken from the official technical sheet. They show a simple point: when it’s cold outside, efficiency drops, so you should choose a model based on a realistic winter scenario rather than the ideal case.
For example, the IGLU Inuit 6 model’s rated heating capacity and COP at O7/V35 are 6.0 kW and 4.92, but at O-7/V35 they are 5.5 kW and 2.75. The IGLU Inuit 12 at O7/V35 has 12.0 kW and 4.63, and at O-7/V35 11.77 kW and 2.41. These figures are taken from the official technical sheet. They show a simple thing: when it’s cold outside, efficiency drops, so the model should be chosen not based on ideal, but on more realistic winter conditions.
Additional context is provided by the operating limits. For models in both series, the heating ambient temperature is specified from -25 °C to +35 °C. The user manual also notes that the system can operate between -25 °C and -20 °C, but capacity under such conditions is not guaranteed.
When evaluating this category, it’s worth counting three things:
- What supply water temperature do you need?
- What is the current heating system in the house?
- What capacity remains on colder days?
If you have underfloor heating, you usually get higher efficiency. If you have old radiators and need a higher temperature, the solution may be different. In practice, this means that the advertised COP without O2 and O-7 conditions does not give the buyer the full picture.
When is an air-to-water heat pump not the best solution?
Air-to-water heat pump is not always the best solution when chosen without evaluating the home’s heat losses, heating system temperatures, and installation conditions. The biggest mistake is usually not the device itself, but an inaccurate selection.
If a house needs a very high, constant supply temperature and the radiator system is old and unbalanced, simply replacing the heat pump may not deliver the expected result. In this case, you need to check whether 65 °C will be sufficient for the system, or whether it is more practical to choose a model that can operate up to 75 °C, such as IGLU Inuit Mono. It is also important to know that a lower temperature curve usually suits underfloor heating, while radiators require a different mode. This is clearly visible in the IGLU Home Next control system, where the heating curve and the underfloor heating curve are adjusted separately.
Another limiting factor is installation quality. The user manual states that installation and servicing must be carried out only by IGLU TECH certified installers, and improper installation may void the warranty. If you’re looking for the cheapest installation without clear technical logic, you risk not only comfort but also the warranty terms.
What should a buyer know about support for heat pumps in Lithuania?
For a buyer in Lithuania, it’s worth viewing support as a way to reduce the investment, but not as the main reason to choose a specific model. First, the solution itself must be suitable, and only then does it make sense to arrange financing.
IGLU heat pumps meet the key technical requirements of current support measures and can be financed under calls administered by the Lithuanian Energy Agency. It is also specified that one of the most important conditions is a COP of no less than 3.0 at +7 °C. In the IGLU Inuit technical data, COP at O7/V35 ranges from 4.26 to 4.92, while IGLU Inuit Mono ranges from 4.51 to 5.10.
The support mechanism itself is simple—the reimbursed portion of eligible costs usually amounts to about 30–60%, depending on the measure and call conditions, and applications are submitted via the LEA system. If you plan to replace an old boiler, it’s worth following information on state support for heat pumps and at the same time prepare the technical data, invoices, and installation documents.
What sets IGLU TECH apart?
IGLU TECH offers IGLU Inuit, IGLU Inuit WT, IGLU Inuit Mono, and IGLU Inuit Mono WT heat pumps with specific model codes, capacities, and technical limits. This approach allows you to select equipment more precisely for the home, rather than offering one universal option for everyone.
Second, IGLU TECH provides remote control and monitoring through IGLU Home Next. In the app, you can see electricity consumption, generated thermal energy, COP, system status, errors, hot water schedules, and even thermostat zones for up to 15 rooms. In practice, this means the heat pump is not a black box you only remember when it breaks down.
FAQ
Is an air-to-water heat pump suitable for an older house with radiators?
Yes, but the most important thing is to assess what supply temperature your system needs. If your radiators require a higher temperature, it’s worth looking at models that can operate up to 75 °C and not limiting yourself to nominal capacity alone.
How do IGLU Inuit Split and IGLU Inuit Mono differ?
The main differences are the construction, refrigerant, and temperature capabilities. The IGLU Inuit Mono series uses R290 and can reach up to 75 °C flow temperature, while the IGLU Inuit series is generally aimed at up to 65 °C.
Can the heat pump be controlled by phone?
Yes, the IGLU Home Next app lets you adjust temperatures, monitor energy statistics, view system status, create hot water schedules, and log faults. This is stated in the official user manual.
Is the WT model always better than the standard one?
No, the WT model simply has an integrated hot water tank. It’s more convenient when you want a compact, all-in-one solution, but if your home already has a suitable separate tank, the standard model can be more flexible.
Is it possible to receive state support?
Often yes, if you are replacing an old, inefficient heating unit and meet the call’s conditions. The measure itself is administered by LEA, and the exact requirements and funding amounts depend on the specific call.
Where should I start if I don’t yet know what capacity I need?
It’s worth starting with an assessment of the home’s heat demand and the existing heating system. Square meters alone aren’t enough, because the same area may require a very different model due to insulation, radiators, and hot water demand.
What should you do next?
If you are considering where to buy a reliable air-to-water heat pump for a home, the most rational path is not to choose based only on a promotion or the most popular capacity, but to request an exact selection tailored to your property. IGLU TECH can help assess whether you’re better suited to IGLU Inuit, IGLU Inuit Mono, the WT version with an integrated tank, or another heating and energy solutions option. And if you want to move on to a specific step, it’s worth getting in touch via the heat pump selection consultation form to get an offer tailored to your home’s situation.
