Air heat pump has become some kind of magic tool, which reduces the heating expenses just like that abracadabra like magic it works! The threshold to purchase a new appliance is quite low due to the fact that the prices of pumps are low and they are easy to install. If it worked, fulfilled our wishes, paid it back in a couple of years, we could enjoy the half-free warmth. This magic tool has great expectations; myths and beliefs that we wanted to find some answers to. Are the recommended values the manufacturers correct? Are the arguments of the markets true? Is it reasonable to use the air heat pump in very low temperatures? What should be taken into account when purchasing an air heat pump and installing it? Are there differences between different manufacturers? (From Rakennusmaailma magazine 6/2006)
Many customers have been happy with their choices, but also many customers have been disappointed. Business has not always been professional. Independent DIY-men have been tempted to install the appliance themselves. Misjudgements have been made also concerning the size of the pump. Salespeople have not always been responsible enough for the choice of the appliance or the salesperson has had insufficient expertise, unless completely just wanting to sell the product at any price.
A typical air heat pump remote control has the basic functions on the top. Under the flap there are more functions and fine adjustments depending on the appliance.
About the plentiful supply
We invited air heat pumps on our market from the most common size class, which would suit a 150 m house. They should be new so-called inverter models whose functions can be adjusted so that the appliance reduces power output when it reaches the adjusted temperature and also maintains the temperature. Importers of appliances could offer their best model on the market suitable for the purpose. We got 10 air heat pumps which were divided into two groups according to their advertised heating power output: so called 9 and 12 series. The final evaluation does not make any difference between these groups, as there was no consistency in the results in this case. A good 9 series appliance is better than an average 12 series appliance.
The price level of appliances was starting from 795 (Ultimate) at its cheapest and the most expensive was 2500 (IVT, only installed). Usually installation costs circa 600.
COP is everything?
The energy effectivity of air heat pumps is expressed with a COP factor (capacity on power), which expresses how effectively the used electrical energy is transferred to heat energy. If, for instance, COP is 3,2 it means that 1 kW produces 3,2 kW heat. You can get that comprehension of air heat pump energy effectivity that it creates more heat energy than it uses electricity. It is not, however, a perpetual motion machine. Besides the electricity the pump uses, it also uses the open air as endless energy storage. Pump only transfers this heat energy from open air to inside. Based on our measurements we are sure that the COP factors advertised by the manufactures have very little to do with the energy effectivity in practise. The factors advertised by the manufacturers are even if they were measured with a standard should not be a factor used in the savings reached with the pump. Also, the factors should not be based on nullification calculations The good side in this circus is that the manufacturers are using the same standard. The same standard helps us to compare the different models of the same manufacturer and also the models of different manufacturers. It should be noted that the practise is not the same.
When the covers are removed, it is difficult to recognize the interior units from each other. Ingredients and structures are like clones. Even the wall attachment plates suited each others attachment holes.
The exterior unit of the air heat pump opened. It reveals basically the same view that is dominated by the fans winged wheel. The compressor unit is on the side and the steering unit is above.

Air heat pumps electricity behind the residual current device
Interior and exterior units are joined together with a connection cable. The electricitys main input (AC 240 V 50 Hz) is brought, depending on the model, to the interior or exterior unit. Power input came to the exterior in Toshiba, Mitsubishi, Hitachi and Daikin, and to interior unit in Haier, Ultimate, Fujitsu, Sanyo, Panasonic and IVT. The Ultimate, Fujitsu and Haier had the input cable with a plug in the interior unit. IVT and Panasonic had the input cable in the interior unit but no plug. Sanyo, Toshiba an, Mitsubishi, Hitachi and Daikin did not have any cables. All models had the power input as a singe-phase, zero and earth cable. Besides the power input also there was a connecting cable needed between the interior and exterior units. Connecting cable was either with 3, 4 or 5 conductor depending on the model. The conductor cut area was min 1,5 mm. Special attention should be paid for power input when installing. In outdoors use in fixed installation the normal MMJ installation cable is enough, but it is recommended that a rubber cable is used which is min. IP44 classified. The installations should follow SFS 5000 standard. All measured models had the electricity cables and refrigerant substances pipes on the same side of the exterior unit; so extra attention should be paid on the safety especially when installing the pump. A registered mounter can install the pump regarding the electricity and cooling installations. The installation of the air heat pump is problematic especially in older houses, which have no protective earth plug box indoors. Interior unit can be connected to the plug box of class zero but it is desirable that the plug box planned for the pump is nullified from the closest distribution box. This would certain the protective earth for both units. Houses, which have earth protected plug box, have no such problems. Those air heat pumps, which have the power input to their exterior unit, the air heat pump is installed to the nearest plug box. The modern house plug boxes are also equipped with residual current device so the installation is safe. If you need an extra plug box for the air heat pump, it should be equipped with a residual current device or a separate plug box should be outside the reach above it and it should have a warning sign to limit its use. Air heat pumps should always be equipped with a residual current device
The installation of refrigerant substance and pipes
Generally speaking the sizes of air heat pump pipes are similar. Panasonic and IVT had bigger pipes in the gas side and Ultimate had a different installation manner. The size of the pipe is depending on the power of the appliance, size was on the liquid side 3/8 and IVTs and Panasonics gas side. The tested appliances were delivered without ready pipes except in Ultimate, which had a prevacuumed pipe. It is satisfactory for moth installations in a house where there will not be many piping. Other appliances had only couplings with flange connection and pipes with flange connection in interior units. They reach the outside of normal houses wall structures.
Because of flange connections the welded connection are not needed but at the same time there can be four possible leakage points. Ultimate has pipes with fast couplings, which can be joined to the exterior unit and removed quite easily. Instructions were deficient. Extras power was not needed. Removing the exterior unit should be made cautiously because the cover flies away when the spring goes off.
Typically the exterior units side has the electricity and refrigerant substance
Manufacturers prefer to advertise only energy effectivity which is based only on one temperatures COP: usually for example 7 degrees Celsius, which is according to the standard 14511 and is very favourable for the factor. Deviating from our measures and evaluations we take the Finnish climate into account the temperatures vary significantly. We considered it important making a difference between so-called normal use + 7 to t and cold weather use from 7 to 20 degrees. Unlike it was expected, according to our measures it seems that pump is worth its use yet in 15 degrees below zero and many appliances can be used even in 20 degrees. Even though the COP factors do not reach any other levels than those announced by the manufacturers, the results are positive. In principle it is worth letting the pump play as long as the factor is greater than 1. Saving is collected all the time even if they were lower than promised.
Nobody should believe a salesperson that claims that the pump will reduce half from the electricity bill! If the houses heating economy is in order, the heating costs are already small; any extra savings cannot be expected. The reached saving is focused only and only on the energy costs of buildings heating. The greatest benefit from the pump is gained in a house warmed with electricity and where heating economy is weaker. The pump can effect only on the part of the electricity bill of heating, on that part where already water heating, lightning and other household use of electricity have been removed. Also it must be remembered that the pump uses electricity itself, which has a remarkable value in the savings. The pump is a great benefit especially in summer when its used for cooling. This benefit is however, experienced which increases the consumption of electricity. As our objective was to clear out the economical benefits, we excluded the cooling characteristics from the evaluation.
Are the differences between pumps?
One of our main objectives was to clear out the differences between pumps and to put them in correct order. The best COP factor was 3,30 and the weakest was 2,15 in 7 degrees above zero. Also there were differences between our measurements and the values announced by the manufacturers. In out test method the pumps were used to their full potential, they were used for a week with maximum power. All pumps functioned during our evaluation and there were no faults. We would not predict the reliability of pumps or their lifetime. In principle a cheap and reliably working appliance pays itself back faster then the more expensive. We continue to focus on the differences that in practise the COP factor marginal differences are smoothened to the savings or losses caused by the place, places suitability, the placement and finally the way it is used.
The interior unit of air heat pump filters inside air. The purpose of the typical plastic coarse and paper fine filter is to prevent trash from getting in to the interior units battery. Some of the appliances have also an electrical filter and/or an electrical air freshener.
The use of pumps for heating is still on a pioneer level, even though its success has grown remarkably. Air heat pump technique is familiar and it has been long in the production but in principle they are just cooling appliances and the heating use of cooling appliances especially in cold climates is still in baby shoes. New models come up to the market all the time and therefore the model purchased a year ago is already an old model.
The discussion about air heat pumps is also hot and it can be compared to tuning your car or getting more power to your computer. The air heat pump is a saving appliance and if you use it, it brings you savings. Savings are not just so high as it has been promised. After returning to the back to earth we recommend purchasing an air heat pump for everyone who think it is a suitable extra heating source. This is the case especially with those people who have electrical heating. Air heat pumps are developing continuously. It is not worth postponing the purchase to a new generation model. Without the air heat pump the only way to get savings is the traditional way.
Electricity is saved
This table includes the electricity saving potential for all pumps. A house (150 mheated with electricity, consumption of energy is kWh per year.
Electricity used by air heat pump per year 0 degrees kWh Heating energy produced by air heat pump per year 0 degrees kWh 20048 Total energy, energy consumption + pumps intake energy kWh Saving potential kWh 11768 8168
Daikin Fujitsu Haier Hitachi IVT Mitsubishi Panasonic Sanyo Toshiba Ultimate
The starting point is a house which is heated with electricity and it consumes kWh per year. If the temperature goes to zero but not below that (we used the mean temperatures of Helsinki) - the air heat pump could save even kWh from a kWh total consumption. This is where the appliances differ from each other. Because this table is only calculative, its results cannot be used and has not been used in this evaluation. The base of our calculations is however in the measurements of the evaluation. We would like to mention that this is only an example of extreme weather conditions (0 outdoors, pump request 20 degrees and its airflow to the maximum) and nobody should believe that his huge energy savings could be reached. If the temperature outdoors is over +7 degrees, there is no need to heat and when we have lower temperatures, the effectivity decreases quickly. And, after all, nobody needs +30 degrees inside continuously. The colder the weather gets, the less differences there seem to be between the appliances. It seems that the savings are depending mainly on the pumps input power. According to this theory, those pumps that have a low input power and a high COP, make greater savings but also those with a low input power and low COP, there are more savings than with those with high input power and high COP factor. In principle the over measuring of an air heat pump is not benefiting anybody; on the contrary a slight under sizing could make more savings.
This is how we evaluated
Energy effectivity is divided in two parts; the more importance has been given to the effectivity of the pump in higher temperatures, because more advantages are gained. We did not want to pass the effects in low temperatures because they tell about the suitability to Nordic circumstances. Because we have temperatures below minus 15 only rarely, and more rarely in the future, the importance of the value is smaller. The consumption of electricity of the appliance has a great effect on the how much heating electricity is saved. It is a central cause for purchasing an air heat pump. Regarding the points we used the daily average on a scale +7 -7 degrees. The consumption of appliances electricity increases because they have been used to the full potential all the time. This is not a normal condition. The airflow efficiency effects remarkably on the level of appliances energy effectivity. The more cubes per hour, the better. The noise was measured from 3 distances, 1 metre, 3 metres and 5 metres but we counted only 3 metres to the evaluation as an average of 10 measures. The results measure from one metre did not have any meaning and other noises disturbed measuring in 5 metres. Changing the values of points the desired characteristics can be highlighted.
