Here are the best heat pumps

IVT provides the most warmth for money, while Mitsubishi gives the most heat when it’s especially cold.

Here are the best heat pumps

Are you planning to install heat pump this year? The Consumer Council has published a new test of air / air heat pumps, conducted by SP Sveriges Tekniska Forskningsinstitut on behalf of the Swedish Energy Agency. Combined with a similar test from March this year, one model from IVT and one from Mitsubishi comes best.

According to the Consumer Research Council, Jogrim Aabakken, you should choose the Mitsubishi model if you live in a particularly cold area (inner easternland, inner Finnmark and parts of Troms), and the housing is also large and maybe also poorly insulated. In most other cases, the IVT model will work satisfactorily.

The price of the Mitsubishi model is NOK 24 900, – complete. The corresponding price for the IVT model is NOK 23 900, -.

Heat Requirement

When assessing heat pump, the heat demand will be crucial so as not to risk the risk of choosing a small heat pump.

– If you live in an area with an annual average temperature of 3-4 degrees or higher, the IVT model is a very good choice. However, if you live in an area of ​​lower annual average temperature and live in a large or poorly insulated housing, you should consider the Mitsubishi model. This does not save as much power as the IVT model, but returns a lot of heat even when it’s really cold outside. As a result, you will be less dependent on additive firing in the coldest months, Aabakken expands.

Multiple Thousands of Lots to Save

The Consumer Council has paid particular attention to two factors when considering the heat pumps: heat output and annual heat factor (annual COP). Mitsubishi FD Heat Kirigamine 6.6 comes best when it comes to heat output, while IVT Nordic Inverter 12 KHR-N gets the best results on heat factor.

The heat output describes how much energy the pump delivers at a given outdoor temperature. At -15 degrees, Kirigamine produces 6.6 4.3 kW, while the poorest model in the test delivers 2.8 kWh.

The heat factor indicates the ratio of the heat pump output and input power. The larger the number, the more heat efficient the pump will be and the lower the power bill.

This gives the best effect of the heat pump in the cold

With an annual heating requirement of 13,000 kWh (equivalent to power consumption of 20,000 kWh), the difference between the Nordic Inverter 12 KHR-N and the worst model will be 2600 kroner in lower energy consumption.

How to choose heat pump?

The choice of heat pump will generally involve consideration of several factors such as price, heat output, heat factor and noise. The Consumer Council has set up a wizard for help:

1. How cold is that about your home in January?

2. What annual average temperature is at your place of residence?

3. How much energy do you have?

Based on how much power you have per year. This number will usually be found on the invoices you receive from the network owner and power supplier. Multiply the number by 0.64 (because Norwegian households average spend about 64 percent of the space heating). Example: 20. 000 kWh per year x 0.64 = 12. 800 kWh in heating per year.

And in the answers you get, you can go to the Consumer Council’s test results and find the model that seems most suitable.

However, the Consumer Council emphasizes that not all of the models on the market are included in the test.

Select a known brand

Three important terms

Heat factor is usually called COP (Coefficient of Performance). Describes the ratio of pump power output to heat and power input. 2.0 in heat factor / COP means that the pump produces twice as much heat as a regular panel oven would have done with the same energy consumption.

Annual heat factor (“COP-year”) describes the heat factor a pump manages to produce over an entire year. The higher the annual heat factor, the lower the power consumption and the lower the electricity bills on you. One of two factors The Consumer Council has chosen to emphasize in our analysis.

Heat effect describes how much heat the pump manages to produce under certain conditions. Generally stated in kilowatt (kW). 1 kW = 1. 000 watts. The heat output will usually decrease with decreasing outdoor temperature. The higher the heat output, the greater the chance that the heat pump will manage to keep your home warm. One of two factors The Consumer Council has chosen to emphasize in our analysis.

Information Manager at Norsk Varmepumpeforening (NOVAP), Einar Gulbrandsen, emphasizes the importance of choosing a pump built for Norwegian conditions, and in this regard, he shows that next year there will be a new standard for energy labeling. The former A-class will receive an addition with A +, A ++ and A +++.

The advantage of increasing the scale is that you as a consumer can easily find the most energy efficient air / air heat pump. The new brand will emphasize that there is a big difference in the performance of heat pumps, “they write on their web pages.

– In general, we tend to advise the consumer to choose a known brand, and also ensure that the plant is fitted by a professional. One can buy the best pump in the world, but if installed improperly, it will save you a lot of savings and break down quickly.. On our website heat pump info. no, the consumer will find a list of installers approved by us.

Gulbrandsen also has the right to ask for a reference project, as well as to purchase from a supplier who has an importer in the back because it provides additional security in relation to the complaint.

Noise

In its test, the Consumer Council has placed relatively less emphasis on noise, because it will often be a subjective size.

– We do not recommend placing too much emphasis on the noise measurements in our test. Noise is perceived differently and it may not be that everybody finds that the pump that produces the lowest decibel in the laboratory is the pump actually experienced as the quietest. To be sure not to be annoyed by noise, you should therefore consult a neighbor or dealer and listen to the pump with your own ears, Aabakken.

In general, however, we can say that the latest models on the market are silent, he adds.

Maintenance Important

According to Gulbrandsen, an air / air heat pump has an expected life span of 10 years.

– But it can work well for 15 years. However, it is crucial for the lifetime that there is a regular maintenance. We recommend service every other year.
