De maximale tarieven worden jaarlijks vastgesteld door de Autoriteit Consument & Markt. Hierbij een uitleg over de tarievenposten van 2024:

• Warmth: the rental of the delivery set. The delivery set is the installation needed to bring the hot water from the hot cold storage system safely to the indoor installation for space heating and/or domestic hot water preparation.

• Domestic hot water comfort 10 l/min: the availability of 10 liters of hot water per minute. This means that there will be enough hot water for a rain shower or the possibility of having hot water available simultaneously in the kitchen and the bathroom.

• Heat exchanger: heats the cold drinking water that flows to the hot water taps in the kitchen or bathroom. This is done via a separate system. As a result, the drinking water does not come into contact with the hot water from the WKO system.

• Measuring rate: costs for measuring your heat consumption. This is achieved by measuring the inflow and outflow of heat in your home with a calibrated meter. The difference is the heat output measured in m³ (hot water) or GJ (heat).

• Cold: fixed fee for the provision of cooling.

• Every 2-3 hours the system checks if it needs to heat/cool. It takes 8-10 hours before the room temperature can be adjusted to the requested temperature. If you want to go from a low temperature to a high temperature, this costs extra power. That is why we recommend that you leave the thermostat at a constant temperature;
• Try not to leave windows and doors open unnecessarily to avoid heat/cold loss;
• The balance ventilation on a normal/low setting reduces the flow of cold/hot outside air into your home;
• It is important that the floor heating can properly dissipate the heat;
• Handle tap water sparingly.

The energy meter manual, like all other important documents, can be found on the documents.

Cooling starts working when you turn on the automatic control for heating/cooling. You set the AUTO programme by keeping the P button pressed until AUTO appears in the display. Cooling starts when the room temperature has reached the lower limit of 21 °C and is at least 3 °C higher than the desired temperature. When the cooling starts, you will see a snowflake on the display. After some time, the floor heating distributor should be 16-18 °C.

Set the thermometer to the absence function/airplane mode (airplane symbol) on your device. The absence function/airplane mode regulates the temperature of your home to the set absence temperature but does not switch off the supply of cold or heat. Please note: The absence function does switch off hot water. To stop heat supply, close the leftmost red valve at the bottom of the Driesbox. Via settings (gear icon) you can specify the number of days of absence.

During summer, you can cool your home by setting the thermostat to a temperature lower than 21 degrees, say 15 degrees. This prevents your house from heating up when the temperature is lower than your thermostat (for example 20 degrees).

Heat or cooling can be switched off and on. The procedure for cooling is explained below. Switching cooling off works as follows: You can make a one-off free request via a mail request with the subject line "Koeling uit + [street-house number]" to service@warmkopgrasweg.nl to turn of your cooling. You do continue to pay the fixed monthly fee for your cooling. Would you like to turn the cooling on again? You can do so by sending an e-mail request with the subject "Koeling aan + [street-home number]" to service@warmkopgrasweg.nl. A connection fee of €42.95 will be charged for this.
