Heat pump can reduce your power bill while making it warmer in the home.

As soon as you earn the heat pump

Still remember winter last year when homeowners did everything to keep the blast out of the house?

You also probably remember how the electricity prices jumped and you worked to find the most optimal heating method to save power.

This year you may be planning to be our lead and do something about your power consumption? Heat pumps have shown that they provide both heating comfort and lower power billing.

Air-to-air heat pump

Here we give you an overview of what’s on the market of air-to-air heat pumps. This is the most common heat pump in Norwegian homes today, and according to the Norwegian Heating Pump Association in 600. 000 Norwegian living rooms.

It extracts its heat from the outside air, but it means that the power factor (COP) decreases with falling temperature outside. According to Enova, under two to five degrees, a condensation problem can also occur, which in turn causes the component to be defrosted on a regular basis.

Air / air heat pumps cost according to Enova between 15. 000 and 20. NOK 000 including assembly and they have a life span of 10 to 15 years.

In the overview below, prices start just under 20. 000 kroner and ends at over 30. 000. Installation will be around $ 4,000, but will vary from supplier to supplier.

Panasonic sets its prices with assembly.

Three variants

A heat pump is mainly available in three different solutions: air-to-air, air-to-water and water-to-water.

According to information officer at Norsk Varmepumpeforening (NOVAP), Einar Gulbrandsen, it is installed around 600. 000 heat pumps in Norwegian homes.

– Heat pumps are starting to become quite common in Norwegian homes, and air to air is the one that it installs most of, he says to clicks. no.

– Air to water, however, is a good option if you already have water-borne heat.

Good power factor even in cold weather

The main advantage of the heat pump is that it provides a better heat economy than most other solutions. It is the pump’s annual heat factor that determines this. Its higher annual heat factor, the better the economy will have.

The challenge with the air-to-air pump is that the power factor decreases, the colder it gets out.

The downside of air as an energy source is that the energy extracted from the air is sinking with falling temperatures, but the developments that have taken place on the market have led to the quality of the products being good. says chief scientist at Sintef, Petter Nekså, to click.com

According to Gulbrandsen, the power factor could sink down to 2 at minus 25 degrees.

– At low temperatures it will be necessary to supplement so-called heating heat in the form of other heat sources, adding Nekså.

What will therefore be decisive is what energy the pump delivers when there are many minus degrees out there. Most vendors operate with minimum and maximum values ​​for heat output regardless of temperature, while some (p. a General) focuses on heat output at low outdoor temperatures. In the overview below we have chosen to present the maximum figures without regard to outdoor temperature, so that the overview becomes as clear as possible..

Earnings within five years

According to Gulbrandsen, the life of an air-to-air heat pump is around 10 years, and then the entire plant must be replaced.

– However, we expect that such a plant will be served within three to five years.

According to the magazine of the Homeowners’ Association, Housing & Housing, the earnings of a heat pump will depend on the following variables: The investment cost of the heat pump, the amount of heat demand the pump covers, the life span and the electricity price.

The rainfall

Total power consumption: 25,000 kWh

Annual heat factor: 2.4

Investment: 20,000 kroner

Lifetime heat pump : 10 years

Annual depreciation (linear) heat pump: 2000 kr

Proportion of heating: 60%, of which the heat pump covers 60% of this again = 9000 kWh.

kWh consumption heat pump: (25,000 x 0.6 x 0.6) / 2.4 = 3750 kWh.

Savings: 9000 kWh – 3750 kWh = 5250 kWh.

If the investment is to be paid, the total electricity price (incl. net rental) is above 38 øre / kWh.

At the price of 50 øre / kWh, the heat pump is earned in 7.6 years.

At the price of 70 øre / kWh, the heat pump is earned over 5.4 years.

At the price of 90 øre / kWh, the heat pump is earned over 4.2 years.

Important Moments of Purchasing

According to Gulbrandsen in NOVAP, you should only purchase heat pump from an authorized dealer.

– Buy a well-known brand from a dealer associated with an official importer, among other things because one will receive a heat pump that is adapted to the Norwegian climate. What one can experience when buying a pump that is not adapted to Norwegian conditions is that the outfit can be quite powerful.

Gulbrandsen is also advised to have a supplier at first inspection, which can determine how much pump one needs.

Installation important

Another important feature of the heat pump is the installation. According to Neksa at Sintef it is important that the assembly of the heat pump is done correctly, and by professionals.

– Incorrect installation can lead to noise problems.

Gulbrandsen adds that a malfunction can also reduce the life of the heat pump.

Heat pumps and noise

According to Støydemperen, the member magazine of the Støyforeningen, it is the issue that is primarily a challenge when installing heat pump.

– It is important to check if the noise applies inside or outside. Utility is the noiseiest thing. This is especially true of the compressor. It emits low-frequency noise, which is more difficult to dampen than the more high frequency fan noise, says NOVAP, Bård Baardsen, general manager of the magazine.

Leakage from the heat pump can cause the outdoor unit to no longer bother, as well as worn storage can also lead to more noise.

Many complaints about noise

– We still get complaints about noise from heat pumps, says advisor at Støyforeningen, Pål Jensen, to click. no. He advises to be careful not to place the outfit to close the neighbor’s bedroom window.

– When buying a heat pump, you should select that pump with the lowest volume of the same capacity.

Jensen says that a noise level of 30 dB (A) can be disturbing in a bedroom.

– 20 dB (A) corresponds to razor from leaves, 30 dB (A) corresponds to a whispering conversation, and 40 dB (A) is level with a freezer or a quiet office.

The sound level is usually set as the so-called sound pressure (LP) and entered in dB (A).

Panasonic’s main range of consumer air / air heat pumps consists of 8 models and 4 different product ranges with a maximum thermal capacity ranging from 5000 W to 7700 W. Two of these are floor models.

Panasonic indicates that the smallest models from 5kW to 6kW fit in homes up to 100m2, while housing between 100m2 and 250m2 needs the models that deliver a minimum of 6kW. According to Panasonic, housing over 250 m2 must have their largest model, which has a maximum heat capacity of 7.7 kW.

EcoConsult AS, an official distributor of Panasonic heat pumps, states that categorization is only meant as a tutor to provide a picture of the effect variations.

The largest model has a maximum sound level of 46 dB (A) while in its quietest mode, “noise” with 30 dB (A), a bit more than a blade that rages in silent weather.

The smallest model has a maximum noise level of 39 dB (A) and a minimum level of 22 dB (A).

Prices range from just over 17,000 and up to 40,000 kroner, but prices may vary from dealer to dealer.
