This costs a heat pump

This can save you thousands of dollars

Three types of water pumps

Air / Air Heat Pump:

On average, costs about 25,000 kroner.

Best suited to you as:

  • Has a total energy consumption of over 15,000 kWh per year
  • Live in an area of ​​mild winters or have long heating season
  • Has an open floor plan, allowing the heat to be distributed freely to the rooms you want to warm up
  • Living in a home where it is not appropriate to re-insulate or replace windows (because it has been done before or because the accommodation is so new that this is not needed)
  • Has alternative heat sources for the coldest periods.

Air / Water Heat Pump:

Costs between 60,000-130,000.

Best suited to you as:

  • Living in homes with water-borne heat distribution in the house. If not, you should take into account investing in a waterborne heating system as well.
  • Has a total energy consumption of over 25,000 kWh per year.
  • Live in areas with mild winters or have long heating season.
  • In addition, another heating source, such as woodburning stove, pellet stove or panel heaters. Most heat pumps have electrical elements that are automatically connected when the heat pump fails to cover the entire heating requirement.
  • Has a high consumption of tap water.

Liquid / Water Heat Pump:

Costs from 120,000 kroner and upwards.

Best suited to you as:

  • Has a total energy consumption of over 30,000 kWh per year.
  • Has housing with water-borne heat in the house. If not, you should take into account investing in a waterborne heating system as well.
  • Has a high consumption of tap water.

If you want to do something about your power consumption this winter, a heat pump can be a good investment.

But it’s also a relatively big investment and it’s okay to know what to get back for it, and make sure you actually get it.

– A pre-installed air / air heat pump costs around 25,000 kroner. Depending on energy requirements and usage, it can save you between 5000 and 8000 kwh of power a year. With a current price of 1 krone, you can save between 5000 and 8000 kroner, says the general manager of the Norwegian heat pump association, Rolf Iver Mytting Hagemoen.

In other words, you could have saved your money in between three and five years. You should be able to assume that the heat pump has a life span of about 10 to 15 years.

Right now, the electricity price is somewhat lower, and is around 0.8 per kwh.

Three different types

There are three different types of the most common heat pumps; air / air, air / water, and liquid / water heat pumps. In short, the air / air heat pump is the one with the lowest heat output and also the lowest prices.

This is suitable for those who have electric heating beforehand. Newer heat pump models can extract heat from the air out to about -25 ° C, according to the Norwegian heat pump association (NOVAP). In the coldest days during the winter, there is often a need for another heat source as well.

The air / water and liquid / water heat pumps are suitable for those who already have water-borne heat in the home, and also heat tap water at home. The latter two will be a bigger investment than the air / air heat pump, which is also the most common in Norwegian homes.

Too bad overview of what really extinguishes most power causes many to pay too much. This way you can easily save several thousand in winter.

Covers between 60 and 85 percent of the heating

Enova has made an overview of how much you can save on investing in a heat pump, depending on how much energy you have.

With a total energy consumption of 25,000 kwh a year, according to their calculations, you can save 4 800 pounds of electricity per year with an air / air heat pump, considering that the price per kilowatt is 1 pound. This means that you have paid down the heat pump in just over five years.

An air / water heat pump can save you around 8,800 euros if you have a power consumption of around 25,000 kwh a year.

A water / water heat pump can save you $ 13,000 a year if you have an energy requirement of over 30,000 kilowatts a year.

The price of these heat pumps will depend, inter alia, on the size of the housing and the energy requirements. Most liquid / water heat pumps in Norway use rock heat and these are more efficient than air / water heat pumps.

An air / air heat pump should cover 60 percent of the heating requirement in your home, while a water / air pump should cover around 75 percent of the hot water and heating needs. A water / water heat pump should cover 85 percent of the need for heating and hot water.

If you are tempted to turn up the temperature, the gain will disappear with the heat pump.

Many do not save on heat pump

Surveys made by Sifo, however, show that many do not save energy after investing in an air / air heat pump.

One of the reasons for this is, according to the report, “Energy-saving technologies in Norwegian households” that people increase the comfort at home when they purchase heat pump. Some choose, among other things, to increase the temperature from 19 to 23 degrees.

Statistics from Statistics Norway, however, show that households with heat pump have an indoor temperature of 0.4 degrees higher on average than households without heat pump.

Should you save both energy and money on your investment, there are also a number of other things you should remember, both when buying and using the heat pump, according to Jogrim Aabakken.

He is the Test Officer, in the Consumer Council and, among other things, responsible for the Consumer Council’s heat pump guide.

Wall models get clogged on the floor

The first thing you need to do is find out if you want a wall or floor model. Then you have a little less to choose in.

– Be aware that we do not recommend mounting a wall model near the floor, Aabakken says.

What happens if you do it is that the heat does not spread as efficiently. The wall model is built to spread heat right up and down the floor, while the floor model is built to spread heat from the floor and up.

Large or small housing?

Once you’ve determined whether you want a floor or wall model, you need to find out which model is right for your home. Then you have to consider what climate you live in and what effect you need.

– In addition to the climate zone, it is primarily the size and degree of insulation that determines how much power you need. If you live in a small and well-insulated apartment in a mild climate, you will be able to do well with a weak pump that only produces 2 kilowatt. If, on the other hand, you live in a poorly insulated detached house in cold climate, you should buy a powerful pump, which usually produces up to 4 kilowatts or more.

The more open room solutions the home has, the more efficient the heat pump will be. Do you live in a housing with many rooms and narrow doorways and stairways, the heat will not spread properly and you will not use a powerful heat pump.

– People also have different preferences. If you buy heat pump only to save power and money, it will pay to buy a relatively weak pump, as these usually have the highest annual heat factor, or SCOP, as it is called on the energy labels. The powerful pumps usually have a poorer SCOP, but in return they manage to heat your home even when it’s really cold outside, so you’ll less need to add a touch of pan heaters and other heat sources in the coldest months.

– If the company is approved by the importer, the heat pumps they sell will be adapted to the Norwegian climate. You will also be able to get help from the importer if something should be wrong and you want to use the right of warranty, which applies for five years.

A final advice regarding the purchase of heat pump is to purchase heat pump and assembly of the same player, so you do not let the two push the responsibility to each other if something goes wrong.

– We have heard of cases where the company that has sold the pump claims that the installer has made a mistake, while the installer claims it is the pump itself, something is wrong with. Thus, the consumer falls between two chairs. Such a situation is easy to avoid by purchasing a pump and assembly at the same company, says Aabakken.

Other things that can make the heat pump more expensive than necessary are, among other things, that you do not clean the dust filters. With dense filters, the heat pump will have to work harder and you lose money and eventually also warm air.

Do not use auto mode

– Another thing is that many heat pumps come with three settings; cooling mode, heating mode and auto mode. The auto mode should keep people away, Aabakken warns.

When you turn on auto mode and the sun is warming up inside the day, the heat pump will start cooling the home, then reheat it when it gets colder again later in the day. It takes more energy than necessary, so put the heat pump on heating.

Aabakken would also not recommend using night immersion when you have a heat pump. The reason is that the pump works best when it works evenly throughout the day. If it is cold in the morning, it must work extra hard to recycle the temperature again.

Do not want to mount yourself

One last important advice is not to install the heat pump itself. First of all, only F-Gas approved installers have permission to do this and, secondly, it is important that it is installed correctly and in the right place to get what you pay for. Both the company that installs and the installer must be approved.

The Consumer Council has created a heat pump guide that collects data from 15 manufacturers to help you find the right heat pump for your needs. Otherwise, it may also be worth checking out the Norwegian Heat Pump Association’s website, heat pump info. no, for advice and information about going to purchase a heat pump.

It may also be worth noting that you can receive support for purchasing heat pump. Through the Enova grant you can receive up to $ 50,000 in support of heat pump and oil burner removal if you combine several of the solutions that the Enova grant covers.
