• Will the property stay within the family (for now)? Then the new owner can register one the page sign up.
• If the lease is terminated or the house is sold, you can fill out the form on the page move out. Under Who fills out this form? choose I am filling out the form for a deceased family member/acquaintance.

• We recommend not changing the desired room temperature. If you have underfloor heating, it may take 8-10 hours before the room temperature can be adjusted to the requested temperature if you change the desired room temperature. Going from a low room temperature to a high room temperature will cost extra power. Therefore, we recommend leaving 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 underfloor heating system can dissipate heat properly, so do not install insulating floor on top of the underfloor heating;
• Handle tap water sparingly.

In case of scheduled servicing or updates about malfunctions, we will post a news item on the page Malfunctions. If work is going to be carried out in your street or neighbourhood which might interrupt delivery to you, we will inform you in advance.

A heat pump is a device we use to extract heat from the ground or from the air. This heat can in turn be used to heat water, for example. A heat pump actually works like an inverted refrigerator. Instead of cooling, it uses the temperature difference from the groundwater to heat.

A delivery system is similar to a gas or electricity meter box. This is because heat and cold is transferred to your home via the delivery system. A heat meter and a hot water meter also measure the heat absorbed in the delivery system. The installation in your home that heats and/or cools the home and the hot tap water pipes are connected to this delivery set. On the document page vindt u een handleiding en instructie hoe u op de digitale verbruiksmeter bij de afleverset uw verbruik van warmte en warm tapwater kan uitlezen. Bij het project Tuvista in Delft en in Ypenburg zijn de woningen niet voorzien van een afleverset. Hier wordt de benodigde verwarming, koeling en warmte voor het warm tapwater opgewekt door een (gehuurde) warmtepomp per woning.

If you have underfloor heating, make sure when choosing a floor covering that it lets heat through easily. You should definitely not cut, mill, screw or nail into the floor. This will damage the underfloor heating and may cause leakage. Do you want to use glue? Then only use a product that is suitable for underfloor heating. Not all types of floor covering are suitable for underfloor heating. If the thermal resistance (Rc value) of the floor covering is less than 0.9 m2 K/W, the floor covering is suitable. Therefore, always ask your supplier how high the Rc value of the floor covering is. Preferably choose a hard floor covering with a low insulation value, such as tiles, natural stone or linoleum. Cork is not suitable for underfloor heating. Wood, parquet or laminate is usually also suitable, but some wood types are not. Ask your supplier what the possibilities are.

No, unfortunately that is not possible. Energiek only provides sustainable heat and cold supply.
