Are you about to buy an air heat pump and want clear and essential information before you go out among the stores? Then you’re in the right hands. In this article you will find out very important information about heat pumps and at the end you can read about our air heat pump best in test to help you in the search for the best heat pump.
We’ll take a look at some heat pumps that are popular models from the leading brands and see what properties they provide. At the same time, we will explain what different types of heat pumps are available for purchase today and what advantages and disadvantages they have.
It can be useful to compare depending on how you live and sometimes a regular air heat pump can be in the smallest team. However, they tend to be good enough for an ordinary family in a house of normal size. But just in case, you should keep track of the options.
How a heat pump works
Have you ever wondered how your refrigerator works? If you already know that, we can tell you that a heat pump works in much the same way but the other way around. The heat from inside the fridge is emitted on the back while an air heat pump extracts the energy from the solar-heated outdoor air and then transmits the heat to the inside of the house through a refrigerant.
This is true even though it can be several degrees below zero outside and the best air heat pumps are able to extract the energy all the way down to as much as -25 degrees. The energy from the cold air is transformed into warm indoor air and makes it warm and delicious in your home.
But an air heat pump is used not only to heat your house but also to cool it down during hot periods. Therefore, they are also called comfort heat pumps. These are very practical and also the models it is sold mostly by among heat pumps. You don’t have to buy both gadgets to warm up your indoor air while you have to spend money on AC. An entire device can both warm up and cool down and you save both time and money by having it at home.
Some grand heat pumps can be controlled from your smartphone today. This may seem to many to be an unnecessary feature that involves higher costs, but if you like technology and want it warm and nice when you get home, this is an excellent detail. You can control it from all over the world if you like, provided you have internet access. In this heat pump best in test, we have included two models that come equipped with just this kind of finesse, so pay special attention to these two if you would be interested.
One of the heat pumps comes equipped with both remote control and wi-fi control as well as SMS control so you can control the heat or cold with a few simple button presses just the way you want. This is perfect before you go out to the country house on a cold winter day and want to come home to a heated house. Incidentally, cheaper air heat pumps come with a remote control like any other air conditioner or appliance and with these you can also easily regulate the temperature at home.
Considerations when buying an air heat pump
Among the first things you should ask yourself before you acquire a new heat pump or read the heat pump best in test, is how big you want your heat pump to be and how large area it should treat, i.e. how much of your house to heat up.
Of course, it also depends on how much electricity you have. But one thing is certain; you should always choose the larger model if you are unsure because if you take it less, you are at risk of under-dimensioning and not getting enough heat in your home. An air heat pump is a long-term investment and if you have well bought a model, you will probably not buy a new one for a very long time. Therefore, it is important to think first so that you do not make a mistake in price, quality or size.
The advantage of today’s modern air heat pumps is that they are made to be able to heat an entire villa of about 150 square meters or a large floor, but the prerequisite for this is also that the villa or rather the floor plan in the dwelling is as open as possible so that the heat can circulate around.
Heat pumps also have a limit on outdoor temperature in order to convert the energy from the outdoor air into warm indoor air. Usually the limit is around -15 degrees but the very best pumps can also heat houses even though the outdoor temperature is down to -25 degrees.
A very important aspect when choosing a heat pump is to always count on the installation cost in the final price. For some time now, it has been the law that installations of heat pumps must be carried out by a certified professional and not at their own discretion, and therefore the total cost will be greater.
Key properties of a heat pump
An air heat pump or a heat pump has certain characteristics that must be fulfilled in order for you to use it. If you live in a warmer climate, some of these are perhaps less important but if you live in Scandinavia with a relatively cold and raw climate, you must consider that it comes equipped with what is required of it.
- Always choose a heat pump that is adapted to our Nordic climate and that can extract energy even from very cold air.
- It should have the highest possible efficiency. Compare SCOP and COP values.
- Keeping the noise level down is important. Compare the level in dB when you buy a heat pump so you don’t get hit by loud noise and noise at home when it’s running. Keep in mind that all heat pumps have both an outdoor part and an indoor part and that the outdoor part is usually both larger and noisier than the indoor part. It may therefore be a good idea to see how much noise it is making outdoors as well to avoid disturbing neighbors etc.
- Your air heat pump should be energy efficient, partly to get you back all the money you invested in it, and partly for it to be environmentally friendly.
- If you pay that much for an air heat pump, it should be able to act AC in the summer as well. Therefore, take a heat pump that works both in winter and summer and that can both heat up and cool down your house. Most good heat pumps offer this feature as an obvious option, but the really cheap variants do not always have this feature.
SCOP and COP
When talking about the efficiency of an air heat pump, you usually compare in SCOP or COP.
SCOP stands for Seasonal Coefficient of Performance and COP for Coefficient of Performance. The difference is that a COP value gives back as many units as the heat pump consumed. For example, if your pump has 4 in COP, you will get back 4 kW for each unit consumed.
In Swedish, COP is simply responsible for efficiency. This is to figure out how hot your indoor air will be when the outdoor air is at a specific level. For example, at 7 degrees below zero, the indoor temperature should be about 20 degrees. SCOP is instead a total value over a whole year or a certain period of time. It is the COP value that is calculated over a whole year and if you translate SCOP simply into Swedish it will be annual efficiency.
However, you should not fully go on these values, because COP and SCOP only tell you how many units you get back and not anything about the maximum power and capacity. Therefore, it doesn’t necessarily mean that a COP value of 8 generates more heat than that of 4. The value only tells you how much you get back, not how much heat it generates.
Save energy with a heat pump
When you get a heat pump, you may save a lot more energy than if you installed heat-elements, etc.
On the one hand, you notice a huge difference in the sound level, which in the past could annoy gall fever even on the hearing impaired, and price levels have also changed. But mainly it is efficiency that has reached completely new levels. Today’s heat pumps, and even those we list in our best in test, are far more efficient and powerful than those seen 10-15 years ago.
Sweden accounts for almost half of the entire heat pump market today and as many as 2 out of 3, choose a heat pump as heating in their homes when they change systems. It is also said that as many as 90% of all homeowners would recommend a heat pump to other acquaintances or neighbors for both heating and cooling the home.
You can save a lot of money through less electricity consumption with a heat pump – usually up to 25-30%. Of course, it depends on a lot of other factors also such as where in the country you live, what the house floor plan looks like and how much need for heating you have.
If you live in northern Lapland, you naturally need more heat than if you have your house in Skåne. However, the cooling during the summer months may be much higher in the south of the country than in the north, which evens out somewhat.
You also do not need to use the air heat pump as the main heating method if you do not want to. Many have it only as a smart supplement if the cold is on properly or if it gets very hot in the summer. It thus acts as a rescuer in distress during certain seasons when the temperature is above or below normal.
However, you should always have a common supplementary heating system during the coldest season because an air heat pump cannot handle too low temperatures. This is more true for those who live in very cold climates where temperatures climb down properly. But with the right conditions and proper installation of heat pumps, it is generally used to have earned the cost of it already after 3 years.
The best brands on the market
There are three players on the market who sell heat pumps that usually excel a little extra in the best in tests. They also get good reviews from customers and are widely known for holding the positionthe people. This applies mainly to LG, Mitsubishi and Panasonic pumps.
These are particularly interesting because they manufacture heat pumps for the Nordic cold climate and are obvious choices among Northerners. Tests on heat pumps are done continuously by the State Energy Agency and according to them these brands are very good. This authority also does not appoint a single test winner, but presents benefits for different places in the country and what is beneficial precisely for people who live in the area.
The climate must be adapted to the choice of heat pump and therefore it cannot be said that a model is best for everyone. What is a bit negative in this is that companies themselves can appoint themselves test winners and are happy to write various press releases to talk about how their model is best in tests.
If you want to be really safe when you buy a heat pump, you should also visit the Swedish Energy Agency’s website to read about each heat pump’s test values for the place you live. In combination with the other best in tests, you will then get the safest information for your specific needs.
Install a heat pump
Nowadays, it is law that a heat pump must be installed by knowledgeable and competent staff, i.e. a professional who performs the job correctly and who knows how everything should be installed. A knowledgeable person ensures that the pump is properly dimensioned and that it is placed on the best surface of your house. This also applies to both the part that must be outdoors and the part that is placed indoors.
This determines how effective it will be and how much energy saving will be. If a heat pump is misplaced, you can completely miss out on the energy saving and have then thrown out money unnecessarily. Heat pumps should also not disturb either neighbors or residents of the house. The outdoor part tends to be less quiet and therefore it should also be placed in a way that prevents loud, disturbing noises. This must also be borne in mind during the summer months if the heat pump is to act AS AC.
Then the noise can become even more annoying so it is advisable to discuss with the installer where the device is best. If you want to read more about heat pumps and various devices and how heat pumps work and all general information, you can turn to the Swedish Refrigeration and Heat Pump Association.
The reason for having to hire a knowledgeable person who installs the heat pump, is because refrigerants are advanced devices and dangerous if installed incorrectly. They can affect both the environment and the people around it, and that is precisely why this legislation has gone through. This of course means that you will have to pay a little more in the end once you have bought your heat pump, but you can use the ROT deduction to lower the cost.
Owning a heat pump, however, means that your energy costs will be lower and that you will take a step in the right direction to protect the environment. This means that even if you get to expect more money in a heat pump purchase, you will earn it in the end anyway. So a heat pump is a safe investment and will cost you less over the years.
Air/air heat pump and air/water heat pump
There are two types of heat pumps that have two rather funny and surprising names; air/air heat pump and water/air heat pump. So what could this mean? Well, an air/air heat pump is really the same as a heat pump but a simpler variant. It takes the heat from the outdoor air and converts it into warm indoor air that spreads throughout the house via a fan in the system.
Air/air heat pumps should be free with plenty of space around and therefore installed in a central location in the house. These types of heat pumps are a bit cheaper and easier to install and are an alternative to the expensive variants on the market.
A water/air heat pump is an air heat pump that is designed to spread the heat to a water-borne system such as radiators or underfloor heating. This causes this pump to heat up further and acts as “assistant” to the already installed heating system in the house. This way you make more savings and these pumps are also considered to save even more than a regular air/air pump.
They can also heat domestic hot water and save on this heating cost as well. By spreading the heat through the water, the heat goes into all rooms without you risk getting some hidden nooks in the house unheated. With an air/air heat pump you may have to turn up the temperature considerably to make it feel in all the rooms of the house and usually the heat only extends to 150 square meters. Therefore, if you have a larger villa, you should perhaps invest in the water/ air pump that is guaranteed to be accessed everywhere. A major advantage of a water/air heat pump is that it is not equipped with any annoying fan that interferes.
A water/air pump is virtually silent, which can be useful for the sound sensitive. However, it can snap a bit in the water pipes sometimes and that may be a reason to refrain from it. When the heat is discharged into the water pipes, this happens jerkwise and then it can be heard in the pipes. However, you can fix this by mixing colder water with the pump’s hot water before it is discharged into the pipes.
Then the small sounds stop and the clasps go quiet. The sounds have to do with uneven heat distribution. A water/air heat pump is also not a good alternative to very cold climates because it can not use as well of the outdoor air when it is at its coolest. Therefore, this type of heat pump should not be used if you live in the northern parts of Scandinavia.
It is a very good alternative to the expensive rock heating that requires intervention on the surroundings and is complicated to install. If you have a swimming pool, the water/air heat pump can also heat it up if you would like to take a warmer bath in the cold season.
Exhaust heat pump – an alternative
An alternative to the two above heat pumps is the exhaust air pump that takes advantage of old used air in the house and reuses it to heat the dwelling with. It is thus consumed energy that returns to the house in the form of new energy.
To explain how it is done, we can say this; through a fan in the exhaust air pump, ventilation air is sucked out of all wet areas in the house. When this begins to occur, there is a slight faint suppression throughout the dwelling, which means that air from the rest of the house’s remaining room also seeks out the wet areas so that the fan can absorb even more air. At the same time, new air is drawn in from the outer walls and ventilates the house further in room after room.
Now a lot of air circulates throughout the house and this air is sucked into the ductsystem that heats up the air and enters the heat pump that takes advantage of the air that is then led out into the hot water and radiator system. The whole thing may sound a little complicated, but it’s not.
Exhaust pumps take care of themselves and nowadays there have been much better models that are easier to install. The advantage of both exhaust air pumps and water/air pumps is that they can be accessed in all rooms of the house and are not only limited to a certain number of square meters. The disadvantage of both of these options is that they are incredibly expensive generally speaking. An exhaust heat pump and a water/air heat pump can cost tens of thousands of kronor, ranging from SEK 20,000 to SEK 65,000.
They are also significantly larger than regular air heat pumps that do not take up much space. The air heat pumps that we have included in our best in the test of heat pumps, cost around 10 000 SEK and work very well in normal sized villas. But if you have a larger house, the other two types of heat pumps are probably a better option and are also very quiet.
Heat pump test
Since it can be difficult to look like the best heat pump based on all different situations, we have chosen to test three popular products from two of the largest heat pump manufacturers – Panasonic and Mitsubishi. However, the three models that have been included in the test have stood out a little more than others on the market and it is also precisely thanks to the brands good reputation that we have chosen to see if their air heat pumps really stand out as they are said to do.
Mitsubishi and Panasonic pumps as well as LG heat pumps usually keep up in most heat pumps best in tests and rarely appear in damage reports. The article above has described how the different heat pumps work and what types there are. As you can imagine, you can choose between paying lots of money for water/air pumps or exhaust air pumps, but in this best in the test we have completely focused on air heat pumps which are the most affordable option. They are also suitable for normal-sized houses, in which most people live.
If you compare the different pump variants, an air heat pump is of course somewhat limited in terms of the area of the house that can be heated and what they can heat up. An air/air heat pump only generates heat via the air into the air and thus cannot affect the water system that water/air pumps can do. What they are good at, however, is to simultaneously act as an air cooler when it gets hot outside so that you do not have to buy yourself an AC.
If we take this information into account while adding together all the important features that we listed above, we can come up with a fairly clear end result and point out the pros and cons of all three models. However, as we wrote above in this best in test, one must take into account a number of factors and read about scientific test values while comparing price ranges and efficiency s and so on.
It is difficult to select a winner because everyone has different needs and lives in different climates and places. We hope that you will benefit from our best test on heat pumps and that you really ask yourself the questions that we recommend that you ask yourself before you buy a heat pump.
Also, please visit Energimyand review the test values of the different models. The Swedish Energy Agency regularly tests new and older heat pumps, but has tested far from everyone that exists.
1. Mitsubishi FH25 VEHZ 635
We start this best in test on air heat pumps with the cheapest model. Admittedly, it does not differ much in the price level of these three heat pumps, but it is still worth mentioning that you pay the least for this.
Mitsubishi’s FH25 is one of the country’s best-selling heat pumps and is a very powerful heat pump that can generate hot air when the outdoor temperature creeps down to as much as -30 degrees. This heat pump is therefore suitable in a very cold climate and a very positive factor with this model, is that it restarts automatically if the power should go out in case of power failure or similar. The model has an efficiency, i.e. a COP value of 5.52 and a SCOP of 4.9. (Read about COP and SCOP above in the article). This means that for this model it is about 20 degrees indoors when it is -7 outdoors.
With a sound level of only 20 dB, this is a silent heat pump that does not create unnecessary and annoying noise. Mitsubishis have double dampers and this means you can choose which way the hot air is pumped out. You can choose to pump the air up or down and this is useful if you have a two-storey house where the hot air needs to flow upwards. The model also comes equipped with maintenance heating, which allows you to set it to + 10 degrees and keep the house heated if you were going on vacation or want your air heat pump in the summer cottage.
The pump can heat up to 150 square meters of space, which is good enough for a villa. During the warmer seasons, the heat pump can be used as air conditioning and cool down your home. However, it can only cool down 50 square meters of your home. In case of heating, the triple surface applies.
The I see sensor allows the heat pump to detect if there are people in the room and set the temperature based on that information. This means that when the room is empty, it lowers the temperature and when it moves people in the room, the temperature climbs upwards for the best possible comfort. However, this only works in one room and to do this with the whole house is not a good idea as it quickly gets cold.
You can also direct the hot air at people who are extra frozen off to make them feel even more comfortable with you. The model comes with a weekly timer so you can choose how the temperature should be week by week.
In addition to heating your house with comfortable air, the model also includes an air purifier and filter that removes dust particles, viruses, bacteria and pollen.
If you are particularly sensitive or allergic, this heat pump is very effective and makes it easier for you. Mitsubishi FH25 VEHZ 635 is a very good heat pump that is definitely worth buying. The pump weighs 37 kg, is 55 cm high and 80 cm wide on the outdoor part and significantly smaller on the indoor part. So it doesn’t take up much space in your home.
2. Mitsubishi FH35 VEHZ 665
The second model in heat pump best in test and which also belongs to the same brand (Mitsubishi) is a little higher in price range than the last. However, it has slightly higher noise levels, which we notice as negative.
The SCOP value is also slightly lower than the previous model, namely at 4.8 instead of 4.9 and with a COP of 5. It also does not manage the same low temperatures as the first heat pump, but extends down to -15 degrees.
In many states, however, it is similar to our first heat pump in this best in test, but there are some differences, including those we have just described. The biggest feature is that it can be controlled from your tablet or mobile through wi-fi. If it’s a feature that you’re after, you should definitely choose this pump.
When you are at work and long home to a heated home or that a certain part of the home should be warm, you can with a simple push of a button wherever you are, control your heat pump completely according to your own needs. This can also be useful to know if you have a person in the home who is not used to heat pumps or can not set it up yourself. By telling them that they are at home, you can easily make things comfortable for the person by using your phone.
You can, like the previous heat pump at Mitsubishi, also lower and raise the temperature automatically when there are people in the room, or when they go out. If you want to maintain your summer house or house while you are away, simply set the maintenance heat to +10 degrees so as not to cause frostbite and the like.
The Mitsubishi FH35 VEHZ 665 also contains the much needed allergy filter that removes dust, pollen and bacteria for a much cleaner air. This is also a very good heat pump but the price is increased a little extra only because it comes with wi-fi and possible control from your phone. Otherwise, we actually think that the first heat pump in our best in test, had better values and is also a bit cheaper.
Otherwise, it has exactly the same dimensions as the first model so the choice is really quite simple. Buy this if you want to be able to control it from other places and take the other one if this is not needed.
3. Panasonic HZ9RKE-1
As the last model in heat pump best in test and in search of the best heat pump, we have included this more expensive model from Panasonic. This is really a powerful and efficient heat pump, as it generates heat even when it is -35 degrees outside. If you live in the north of the country, this is a perfect heat pump that can withstand very cold temperatures.
With a SCOP of 5.3 and a SEER of 7.8 (the value is for air conditioning and equivalent to SCOP), you can both heat up and cool down your home. To list yet another advantage of this heat pump, we can tell you that it is the quietest model in our best in test at only 18 dB. There may not seem much difference between the different sound levels but the fact is that a single dB can make a difference.
This model is both energy-efficient and at the same time environmentally friendly as it contributes less emissions. It has thus complied with the requirements of the GWP (Global Warming Potential). Its refrigerant is called R32, which is the most environmentally friendly refrigerant. Many other heat pumps use R410A, which affects the environment more, so you can enjoy not only getting more money for other things through low energy consumption, but also because you contribute to the planet’s health.
Panasonic HZ9RKE-1 is equipped with sunlight detection that assesses whether it is light or dark outside. In this way, it regulates the temperature after that, and in the case of more sunlight, it lowers the heat and in the event of darkness or grey, the temperature rises. To control it, you can easily use the included remote control, but you can also connect it to the network and control it from other locations.
When the heat pump has reached the desired temperature, it automatically sets itself to maintain a steady rhythm and to allow the heat to hold on. You can also set it to maintenance heat so that your house constantly maintains a certain type of temperature.
The temperatures you can choose from are +8 degrees or + 10 degrees. Panasonic’s model also has air purifiers to relieve you of dangerous or irritating particles in the air or bad smells like cigarette smoke.
One drawback of this heat pump is that it is very large. This applies to both the indoor and outdoor parts but thanks to its many qualities, this does not do much.
It is noticeable that all three heat pumps that we have tried in this best test, are really produced for Nordic conditions. They are all very effective and keep warm despite the cold wines out there. These pumps thus work to cold areas while they all have a built-in air conditioning to cool you down on hot summer days. The price doesn’t really differ much between the three, but all come with different features that are worth telling you about. The first from Mitsubishi has everything a heat pump should have and to top it all off it is the cheapest in the test.
All the functions it comes equipped with, you will also find in other models at large. However, it cannot be controlled with wi-fi but the question is whether it is really needed. The second model of Mitsubishi, on the other hand, has this function but is slightly less efficient than the first and our third heat pump from Panasonic is really a very popular heat pump thanks to the energy efficient and environmentally friendly equipment.
At the same time, it has everything you could want and even if you have to pay a little more at the beginning, you will definitely earn the entire total cost relatively quickly because it is so energy efficient and environmentally friendly. The only drawback is that it feels a bit unwieldy at times but this is weighed up by the range of top-notch features it comes with.
All heat pumps that are included in this best in test, have a 5-year warranty and important functions such as air purifier, maintenance heating and regulation depending on how people move in the room or what the weather looks like. Most brands that produce heat pumps, develop their models annually or at regular intervals. The heat pumps that we have tested have the previous models that you can look for. There is nothing to say that you absolutely have to buy the latest model on the market.
We do not want to select a specific winner in this best in test, but are content to describe the pros and cons so that you get a better idea what awaits you. What you should ask yourself is what feels most important to you and go on your gut feeling at the same time. It kan be good to go out into the stores and check out all three models before you decide and maybe review your home to designate a place where you can have your heat pump. Good luck in the hunt for the best heat pump!
