EXPLAINED: When should I turn on my heating in Denmark this year?

Energy costs in Denmark are set to reach sky-high levels this winter, which will leave many people wondering when they should start heating their homes and by how much. Here's what you need to bear in mind.

What’s happening?

As a result of supply stoppages for cheap Russian gas, on top of inflation; energy prices in Denmark have been at record levels for months.

Due to the situation, the Danish government has sent money to some homes impacted by high gas prices and parliament is discussing other measures for households. Public buildings are set to see thermostats turned down and outside illumination switched off.

As the temperature starts to drop throughout the country, the heating season is getting underway and many people are wondering about the best way to heat their homes, and if they have to follow any rules.

Does it make a difference what type of accommodation I live in?

The right time to start heating up your home depends on several factors including your own personal preference, the weather, whether you live in rented accommodation or own your home, and on the heating system in your property.

How does the heating system work in Danish homes?

Around 65 percent of homes in Denmark use district heating. This system distributes hot water from heating plants to houses and apartments through underground water pipes. The system is designed to be able to heat a room to 20 degrees when there’s an outdoor temperature of 12 degrees.

This is known as fyringssæson meaning “heating season”, which usually runs from the 1st October to April 30th and is calculated when the outside daily average temperature drops to 12 degrees Celsius and below for at least three consecutive days, and ends in the spring when it reaches 10 degrees or above for at least 3 consecutive days.

Does my landlord control my heating?

A lot of rented accommodation will use fyringssæson and under Danish tenancy laws, landlords are required to supply adequate heating and hot water at all times. A daytime temperature of at least 21 degrees, sometimes 22-25 degrees, is generally recommended in all rooms via the heating system.

However due to energy costs this year, the government has announced that the temperature in public buildings will be set to 19 degrees, unless there are special circumstances requiring it to be higher. Hospitals, care homes and preschool care are exempted. The temperature in public buildings is usually set between 21 and 23 degrees.

The government has also recommended that people reduce their own heating at home by 1 to 2 degrees.

How can I keep track of my heating bill?

Earlier this year, the Danish Parliament made a rule that heating companies are obliged to provide information on energy consumption which is sent to consumers seven times a year during the heating season, where you can see how much heat is used. 

It is worth keeping an eye on energy prices and asking the property owner whether the heating system is optimally adjusted.

How can I use the radiators effectively?

“It’s a common a mistake that people sit in one heated room and leave other rooms with the radiator turned off and the door closed,” Michael Nielsen, product manager with Danish cleantech engineering company Danfoss, told The Local.

“But it’s actually more important to use all radiators at same time to heat the whole house and maybe set them a little lower. You will save energy and get more comfort this way,” he said.

Nielsen also recommends not going below a temperature of 14 degrees inside the home.

“Such a low temperature may lead to unpleasant conditions such as condensation on surfaces and mould on the walls and carpet,” Nielsen said.

Setting your radiator to the right temperature will help it work more efficiently. “In Denmark this is usually 21 to 22 degrees but the public advice is to lower this by 1 to 2 degrees this winter, to save on energy costs,” Nielsen added.

Another important thing is to check your thermostat is working and change it if it’s more than 15 years old.

“You can save around 8 percent of energy consumption on each radiator by installing a new thermostat,” Nielsen told The Local.

How else can I save on heating costs?

There are plenty of ways you can help to keep your heating costs down, the most simple of which are keeping doors and windows insulated with draft excluders, and regularly airing out rooms.

“We recommend airing your house twice a day by opening the windows and turning down the thermostat.
 
“At other times it is better not to turn the heating off completely as it may take more energy to heat up the room again. Instead you should reduce the temperature by 3 to 4 degrees at night,” Nielsen said.

The Danish Energy Agency also recommends the following:

  • Check your house or apartment for any cracks where heat could be escaping.
  • Check your radiators are working efficiently and don’t put furniture right in front of them.
  • Check your windows and doors are keeping heat in or whether they need upgrading.
  • Check the insulation in the outer walls, attic, roof, floors and pipes.
  • Check your heating system is running as efficiently as possible.

Copenhagen to retain but reduce Christmas lights amid energy crisis

Christmas lights on Copenhagen’s central shopping street Strøget will be partially switched on this winter, with savings necessary due to high energy costs.

Copenhagen to retain but reduce Christmas lights amid energy crisis

The decision was confirmed by the head of the Copenhagen traders’ association KCC, Michael Gatten, to local media TV2 Lorry.

“We have to make sure that retail here can attract visitors and Copenhageners. Christmas decorations are a precondition for revenue in shops and cafes. And it’s also a tradition,” Gatten said.

“Copenhageners and people from elsewhere come for a cultural experience of seeing the Christmas decorations in the Inner City,” he said.

Christmas lighting will however be reduced compared to recent years. Energy consumption for the decorations is to be 60 percent lower than last year, according to the report.

To achieve this, the lights will be switched on between 3pm and 9pm. Last year, lights in most streets were on from 7am until midnight.

Additionally, lights will first be used on November 27th, the first day of advent – two weeks later than in 2021.

Several municipalities in Denmark are considering reduced street lighting to save energy this winter, while some towns have cancelled their regular winter ice skating rinks.

Most of Copenhagen’s Christmas lighting energy bill is paid by the KCC trade association, with Copenhagen Municipality also contributing.
