Replace heat pump
Has the time come to replace your heat pump? Here you get help to find out if your heat pump needs to be serviced, repaired or if it needs to be replaced. We also provide more information on how to start the change process.
Good guidelines to keep in mind when replacing a heat pump
Prices vary between the different suppliers and the different types of heat pump. We can give you support and knowledge during your first steps towards a favorable heat pump replacement or a service that gives your current heat pump a longer service life.
We go through several different heat pumps:
- Rock heat pump
- Geothermal heat pump
- Air Water heat pump
- Air-to-air heat pump
We report here the average prices of the most common heat pump installations, including the cost of materials, pump and installation.
You can use these prices as benchmarks but should take in a number of quotes to get the right price. By comparing the quotes, you can easily choose the supplier you know gives you the most favorable price for the need you have. You can request quotes from several different companies at the same time free of charge here
Rock heat pump
Replacing a ground source heat pump is relatively affordable. A large part of the original investment cost is the drilling of the energy well the heat is extracted from. As a borehole lasts for about 40 years, you can hopefully use the borehole you already have, this means that you only need to replace the rock heat pump and the collector hose.
A new geothermal heat pump, including an indoor module, costs around SEK 50,000 - 85,000. In addition, there is an installation cost, which after the ROT deduction, ends up at approximately SEK 7,000. This gives a total price of around SEK 57,000 - 92,000 for replacing a ground source heat pump.
The price obviously varies between different pumps. A powerful heat pump, which has a higher kW, is more expensive to buy but in return gives a higher power and savings.
If you request quotes from different companies and are out in good time, there are good opportunities to negotiate with the suppliers and reduce the cost.
Geothermal heat pump
Replacing a geothermal heat pump costs roughly the same as for geothermal heat as the pumps use the same hardware. However, the first installation is cheaper as it does not cost as much as drilling rock heat requires.
Air Water heat pump
An air-to-water heat pump is usually not as expensive as geothermal and rock heat, it usually costs around 30,000 - 60,000 kronor. If you count on an installation, which after the ROT deduction ends up at around SEK 7,000, the total price will be SEK 37,000 - 65,000 for replacing an air-to-water heat pump.
Taking in several offers to compare also gives a potential for savings here. However, the cost will immediately be higher if your heating system, for example water distribution to the elements, is poor and needs to be replaced. However, the heating system lasts much longer than the air-to-water heat pump, which has a service life of 15-18 years.
Do not focus too much on the life of the heat pump. The fact that the air-to-water heat pump is cheaper can offset the shorter service life. Instead, focus on what kind of heat pump is best for your home.
Air / air heat pump
The cheapest heat pump solution is an air-to-air heat pump. If you have a relatively small area with an open floor plan where the hot air can circulate freely, an air-to-air heat pump is well suited for you. In a larger house with walls and other things in the way, however, it is not particularly suitable.
The cost of an air-to-air heat pump is around SEK 12,000 - 25,000 with a few thousand kroner more in installation costs. This gives a total price of approximately SEK 15,000 - 27,000 for replacing an air-to-air heat pump.
Like air-to-water heat pumps, air-to-air heat pumps have a shorter service life than geothermal and ground source heat pumps.
Three suppliers of heat pumps are Thermia, Nibe and Mitsubishi
The art of reducing costs
A heat pump replacement or service of an existing heat pump is ultimately about the heat pump being as efficient as possible. Therefore, it is important not to just go for which heat pump is cheapest. You should also think about how much heat the pump will generate as it affects how much money it can save you in the long run. When you have found the solution you think suits you, you obviously want to get as favorable a deal as possible.
- Take advantage of the ROT deduction so that you can deduct 30% of the labor cost.
- See what the different heat pump companies offer for price.
- It is probably more profitable to continue using rock or geothermal heat if it has already been drilled or dug for it before.
- Mention to the supplier that you are negotiating with a few different heat pump companies. Then they can be even more concerned about winning you as a customer and thus give a better price.
- Focus more on the savings you will make in the long run than on the one-time cost of replacing the pump.

A GUIDE TO HEAT PUMPS
When you are planning to replace a heat pump, it is an excellent opportunity to investigate which heat pump suits your heating needs as these needs may have changed over time. There is really no heat pump that is better than anyone else, there are only heat pumps that are better and worse for the specific needs of the household.
It is good to know the limitations, prices, strengths and weaknesses of the various heat pump techniques when you need to replace your heat pump. Here you get a good overview of different heat pumps, everything from the popular rock heat pump to the more unusual sea heat.
Rock heat pump - the heat pumps' Rolls Royce
Strength: The most efficient variant of heat pump. By drilling a hole hundreds of meters into the ground, you can extract the heat that is stored deep in the ground. The geothermal heat pump can supply many kWh of heat to the property and it is not uncommon today for geothermal heat to be used by tenant-owner associations to heat multi-family houses.
Weakness: The installation is expensive, even if it pays off due to the large savings in heating costs. The type of rock where the energy well is drilled affects the efficiency of rock heat. You can get help analyzing this from a geothermal installer.
Price: New installation including drilling costs around SEK 100,000 - 150,000. If you already have a working borehole and only need to replace the rock heat pump itself, the cost drops to approximately SEK 60,000 - 90,000.
Suitable for: You who have a medium or large house to heat. Is especially good for you who today heat with direct-acting electric heating or oil so these are expensive. What is required is that you have a vacant plot of at least a few square meters where you can drill the energy well.
Installers of geothermal heating: You can use to get up to five quotes for free. More facts about geothermal heat can be found here.

Frequently asked questions and answers about replacing a heat pump
When do I know if I need to change the heat pump?
For the most part, a heat pump lasts for about 12-18 years. How long it lasts depends a lot on how well you maintain it. In order for it to work optimally and last longer, you should bring in a serviceman at regular intervals. But if the heat pump is over 15 years old, it's time to start thinking about alternatives to replace it.
Where can I find companies that replace heat pumps?
As a rule, all the companies that carry out heat pump installations can also replace only the heat pump and connect it to the already existing heat system. If you want help getting in touch with and requesting prices from heat pump companies that have been manually reviewed and selected, you can try our free service The form is quick and easy to fill out and the service can be used throughout the country.
What does it cost to replace a heat pump?
What it costs to replace a heat pump depends on several factors, such as the type of heat pump in question, where in Sweden it is to be installed, how much of the system must be replaced and how well you review the prices of different suppliers.
The cost of an geothermal heat pump is around SEK 50,000 - 90,000 to buy. You may also need to add an additional SEK 10,000 if you need drilling or digging.
Air-water pumps are both cheaper to buy and to install, but you do not get as much power out of it.
Which variant is best?
The different heat pump techniques have different advantages and disadvantages. Which technology is best suited depends on the conditions of your home. Some of the parts that affect which choice is best for your home include how much space to heat, what the floor plan looks like and what the house is for ground type. For normal-sized homes, geothermal heating is generally the most common type of heat pump, but it it is required that it is possible to drill on the site. Air-to-water heat pumps come in second place but they are taking up more and more of the market.

Facts about replacing a heat pump
Depending on the manufacturer, type of pump and what wear it is exposed to, a heat pump today can last for about 10-18 years. On most pumps, it is possible to increase the service life through regular service.
If you have geothermal heat, your heat pump will stop working long before the borehole does. In Sweden, an ordinary borehole can usually be used for about 40 years. The same applies to geothermal installations where the ground is excavated.
This is how the heat pump technology works
How a heat pump works can be easily described as follows:
- Heat is captured from the ground or from the air. There is always heat in the air, even during the winter, which an air source heat pump can use for its heating. There is also solar heat stored deep in the ground throughout the year. This temperature is also relatively stable in contrast to the temperature above the surface which fluctuates with the seasons. By drilling a hole over 100 meters, the ground source heat pump can, via a hose in the hole, benefit from this heat.
- After the heat has been captured, it can not yet be used to heat a home as it is not strong enough. Getting the heat up to the right temperature is the heat pump's task. The heat is sent into the pump, by the heat pump itself or via the hose in the ground, where it is then exposed to high pressure. The increased pressure leads to the temperature also rising and when it has reached the right temperature, it is sent further out into the home. This can be done through a waterborne system of radiators and underfloor heating or through a fan if it is an air-to-air heat pump.
In other words, you get your heat from the heat pump instead of buying heat via district heating, expensive electricity or other sources. This means that you can save money on heating each month, up to 75 percent of your annual heating cost. However, it is important that you have a pump that suits your needs and is correctly dimensioned for the heat pump to be cost-effective. Therefore, always let a heating installer make a calculation and give suggestions on which variant best suits your property based on your needs.
