Heat Pump Savings Calculator for Norway 2026

Work out how much a heat pump saves compared with heating with electricity directly, how much Enova pays towards an air-to-water or ground-source pump, and how many years it takes to pay for itself.

An air-to-air pump often heats only the living room and open areas.

Seasonal efficiency from the data sheet. Higher means more heat per kWh.

The default is Statistics Norway's household average after support, grid rent included. 100 øre = NOK 1.

Heating now uses 12,000 kWh a year. With the heat pump it uses 8,000 kWh. Enova gives no grant for air-to-air heat pumps.

The saving is the electricity you no longer buy, valued at the price you entered. It does not include maintenance, the pump losing efficiency in severe cold, or a rise or fall in electricity prices. The 15-year figure assumes the same saving every year.

Estimate only: results are indicative and are not tax, legal or financial advice. Your actual tax and payments are set by the Norwegian authorities (the Tax Administration, NAV, Customs, the Land Registry) and depend on your personal situation. Check with them or a qualified adviser before you rely on a figure.

How it works

A heat pump (varmepumpe) moves heat from the outdoor air, the ground or a well into your home, so it delivers several kWh of heat for each kWh of electricity it uses. Direct electric heating (panel heaters and heating cables) gives 1 kWh of heat per kWh of electricity, while a heat pump gives several. This calculator shows how much electricity and money a heat pump saves compared with direct electric heating, what Enova, the state enterprise that runs energy grants in Norway, pays towards it, and how long the pump takes to pay for itself.

How the saving is calculated

The part of the heating that the pump covers needs only 1/SCOP of the electricity. The rest is heated as before. With 12,000 kWh going to heating, half of it covered by the pump and SCOP 3, heating electricity falls to 8,000 kWh. The saving of 4,000 kWh a year is worth NOK 4,716 at NOK 1.18 per kWh (117.9 øre). That price is the Statistics Norway (SSB) household average for Q2 2026, after electricity support and including grid rent and taxes. Prices in Norway are usually quoted in øre: 100 øre is NOK 1. Use your own price if you know it, because every kWh you save also saves the grid rent energy charge and taxes on it.

60% of use goes to heating, the pump covers 50% of the heating, and electricity costs NOK 1.18 per kWh (117.9 øre).

Worked example: air-to-air against air-to-water

With the figures above, an air-to-air pump costing NOK 30,000 saves NOK 4,716 a year and pays for itself in 6.4 years. There is no grant, so the net cost is the full NOK 30,000. An air-to-water pump costing NOK 150,000 that covers 90% of the heating saves NOK 8,489 a year. Enova pays NOK 20,000, so the net cost is NOK 130,000 and payback is 15.3 years. Over 15 years the saving is NOK 127,332, which does not quite cover the net cost. Water-based pumps make most sense in a large home with high heating use, or when they replace an old system.

Enova grants for heat pumps in 2026

TypeShare of approved costsMaximum grant
Air-to-airNo grant-
Air-to-water25%NOK 20,000
Liquid-to-water (ground source)25%NOK 40,000

The pump must be connected to a water-based heating system. You apply to Enova before you start, and once approved you carry out the work as agreed and send the documentation before the deadline. Keep the invoice: it must show all costs, the supplier's name and organisation number, and the pump's model name. Enova's pages are in Norwegian; the grant terms can change, so check them before you commit. The calculator only applies the grant to the types above.

If you have just moved to Norway

If your home is heated with electricity, heating is likely the biggest part of your winter bill. Before you buy, check what you can change without a heat pump: choosing between a fixed price and the spot price (see the Norgespris calculator) and knowing how your grid rent is set. Buying a home that already has a heat pump or water-based heating gives you more options. Costs for the home itself are covered in the guide to the cost of buying a home in Norway.

What this calculator does not cover

It compares a heat pump with heating that uses electricity directly, and assumes the same saving every year at a constant price. It does not model cold-weather performance (a pump's real efficiency falls when it is very cold), maintenance, the pump's effect on hot water, cooling in summer, or replacing an oil or wood system. Prices for pump and installation are examples, not quotes. Electricity price changes and any future changes in the Enova terms are not included. The calculator is not advice on which pump to buy: have an installer size the pump for your home.

Frequently asked questions

How much can I save with a heat pump in Norway?
It depends on how much electricity you use for heating, how much of the home the pump heats and its SCOP. A home that uses 20,000 kWh a year, 60% of it for heating, spends 12,000 kWh on heat. An air-to-air pump with SCOP 3 that covers half of that saves 4,000 kWh, or NOK 4,716 a year at NOK 1.18 per kWh (117.9 øre).
Does Enova give a grant for a heat pump?
Yes, but not for every type. Enova (the state enterprise that runs energy grants) pays 25% of approved costs for an air-to-water heat pump, up to NOK 20,000, and 25% for a liquid-to-water (ground source) heat pump, up to NOK 40,000. Both must be connected to a water-based heating system. Air-to-air heat pumps are not on Enova's list, so they get no grant. You must apply and be approved before you start the work.
What is SCOP?
SCOP (seasonal coefficient of performance) is how much heat the pump delivers per kWh of electricity over a whole heating season. SCOP 3 means 3 kWh of heat for every 1 kWh of electricity, so the pump uses a third of the electricity that direct electric heating would. It is printed on the data sheet and the energy label. Pumps do worse in severe cold, so look at the SCOP for a cold climate if you live inland or in the north.
How long does a heat pump take to pay for itself?
In the example above, an air-to-air pump costing NOK 30,000 pays back in 6.4 years. An air-to-water pump costing NOK 150,000 that covers 90% of the heating pays back in 15.3 years after a grant of NOK 20,000, against 17.7 years without it. Higher electricity prices and higher use shorten the time.
Which type of heat pump should I choose?
An air-to-air pump is the cheapest and suits homes with an open floor plan, because it heats the rooms around the indoor unit. Air-to-water and liquid-to-water pumps need a water-based heating system (underfloor heating or radiators), but they can heat the whole home and often help with hot water. Enova's grant applies only to these two types. Ask an installer to size the pump for your home.
How do I find out how much electricity goes to heating?
Compare a winter month with a summer month on your grid company's app or on minside.elhub.no. The difference is roughly what heating uses. Hot water and household electricity run all year, so they show up in the summer figure. If you use a wood stove or district heating as well, the electricity share will be lower and so will the saving.
I rent my home in Norway. Can I get a heat pump?
Installing a heat pump changes the property, so you would normally need your landlord's agreement first. Check your lease before you install anything yourself.
