Affordable connection costs and a long-term energy solution

Locally Produced Heat

In the Vaasa area, 80% of the district heating is produced from renewable energy and waste energy.

We are continuously renewing our production. Our goal is to achieve carbon neutrality across all our operations by the end of this decade.

How We Produce District Heating:

From Wastewater: We recover heat from wastewater at the Pått wastewater treatment plant. Annually, this can generate 60 gigawatt-hours of heat, enough for about 2,000 single-family homes. Heat stored in wastewater is considered renewable energy.

From the Thermal Heat Storage: When there is lots of cheap wind power available, it is used to heat water stored in the Vaskiluoto rock cavern heat storage in Vaasa, which can later on be used to heat district-heated properties.

From Waste: About half of our district heating is produced at Westenergy’s waste-to-energy plant in Korsholm (Mustasaari).

Electric boilers: The combination of electric boilers and the thermal storage at the Vaskiluoto power plant in Vaasa enhances energy production efficiency while reducing emissions from district heating production.

Frequently asked questions about
district heating

How is the district heating system installed?

The property is connected to the district heating network through a district heating pipe. To install this, we dig an installation trench on the property.

During the planning meeting, we agree with the customer on the location of the pipe and the schedule for the installation work. We also assist the customer in deciding where the heat exchanger should be installed. It is usually placed in the boiler room or garage.

The installation of the heat exchanger is the responsibility of the HVAC contractor ordered by the customer.

How long does the district heating installation take?

The entire installation process typically takes about two weeks.

Digging the installation trench, laying the district heating pipe, insulation, welding the pipe, and filling the trench usually take about one week.

The installation of the heat exchanger usually takes a few days. This is handled by an HVAC contractor. The installation is not included in the district heating delivery, so you will need to order an HVAC contractor to handle the installation.

Can district heating be installed in winter?

Installation work is typically carried out from spring to autumn, but it can also be done in winter if needed. If the ground is frozen, excavation work may take more time.

What is a heat exchanger?

A heat exchanger is a device installed in a property that transfers heat from the district heating network to the property. The size of a heat exchanger is typically around 50 cm x 70–80 cm x 30 cm, depending on the manufacturer.

The heat exchanger monitors the outdoor temperature and adjusts the temperature of the water circulating in the radiators or underfloor heating accordingly. This ensures that the room temperature remains consistent despite fluctuations in the outdoor temperature.

How much does a heat exchanger cost and where can I get one?

The price of a heat exchanger, including installation, is typically around 5,000–6,000 euros.
Customers can order a heat exchanger through an HVAC contractor. The HVAC contractor will assist in selecting the appropriate model.

How does district heating work?

In district heating, thermal energy is transferred through water circulating in the district heating network. The water is heated at the district heating production plant and distributed via the network to properties using district heating. These properties may have systems like water-circulating underfloor heating or radiators, which circulate the warm water to heat the indoor air.

A heat exchanger is used to transfer heat from the district heating water to the water circulating in the building’s radiator or underfloor heating system. Similarly, it also heats domestic hot water.

How can I adjust the temperature?

To change the temperature of the entire property, you need to adjust the heating curve on the heat exchanger.

For adjusting the temperature of an individual room in a property with radiator heating, you can adjust the radiator valve.

Does district heating equipment require maintenance?

Before the start of the heating season, you can take the following measures to ensure that everything is in order

  • Check the heating system’s pressure level and top up or vent it if necessary.
  • Check the operation of the control valves and pumps.
  • Check the functionality of the control devices for both heating and hot water.

Also, periodically check in the heat distribution room to ensure there are no leaks in the heating system’s pipes or connections.

When should the heat exchanger be replaced?

District heating is a reliable heating solution. A heat exchanger is long-lasting, and its replacement typically becomes necessary 20–30 years after installation.

Does district heating heat the domestic hot water?

Yes.

How is district heating billed?

You will receive a monthly bill based on your chosen billing method. The bill consists of the energy charge, a monthly basic fee, and taxes.
