WKO Sustainable Energy System

Dunesse is a residential complex completed in 2012 and located in the dunes of Katwijk. The 38 houses are divided into two apartment complexes and are supplied with heat, cold and tap water heating by the WKO installation managed by Vaanster. The number of connections to the WKO installation has grown over time. An apartment complex and a health centre have been built on the Zeehoster site. Both are connected to Dunesse's WKO installation afterwards.  

A total of 90 homes and a number of business connections are now connected to the WKO installation.

Ownership boundary

The ownership boundary indicates which components Vaanster operates, maintains and, if necessary, replaces. The other components are owned by the home owner, who is therefore also responsible for maintenance and possible replacement. For owner-occupied houses, you are the owner of the house yourself. For rented houses, the landlord is the owner of the house.

The image is a schematic representation of the installation in your home. The components in your home may be positioned differently.

Frequently Asked Questions

Malfunction in heat supply

There is a malfunction in the heat supply. This is inconvenient, and you naturally want it resolved as soon as possible.

Who is responsible for the system in my home?

The answer to this question varies depending on the project and is indicated by means of a property boundary. You can look this up by entering the postcode on the homepage. Go to www.vaanster.nl and enter the postcode and house number at the top. You will then be redirected to the webpage corresponding to the entered postcode. There, you will find an image depicting the property boundary of all equipment in the home.

Disturbance in delivery of cold

You suspect a fault in the supply of cold. That is annoying and, of course, you want it resolved as quickly as possible.

Can I adjust my advance payment amount myself?

Yes, you can. In your personal account, you can adjust your advance payment amount under the section "my invoices." However, this adjustment is within a certain range because the advance payment amount must be sufficient to cover the fixed costs.

Malfunction in the hot water supply

It is annoying when hot water does not come out of the tap. It is important to determine:

  • Whether there is reduced hot water or no hot water at all.
  • Whether there is no hot water coming from any faucet (also called tapping point) in the house or whether there is a single faucet from which there is no hot water.
