Sustainable heat

Maximum capacity, sustainable comfort

NEStore® is an innovative thermal storage system based on process water.

The compact thermal battery converts sustainably generated electricity (for example, from solar panels) into heat and stores it in the innovative vacuum-insulated tank filled with process water.

This new technology, originally developed in TNO laboratories, keeps the process water at a high temperature for weeks with minimal energy loss.

Store heat and use it only when you need it

During times with plenty of sun and wind, you store sustainable energy in NEStore®. This heat is stored for later use when this green energy is unavailable from the grid. Use the stored heat with NEStore® for hot tap water or heating in your home, livestock farm, campsite, office building, gym, hotel, etc.

20-30 kWh

Store thermal energy

NEStore® has a large storage capacity, capable of storing 20 - 30 kWh of thermal energy. Suitable for households with relatively high hot water usage, office buildings, sports facilities, hotels, livestock farming and campgrounds.

Innovative insulation developed for real impact

Technology developed in TNO laboratories

Easy installation, 7-year warranty on insulation

The installation of NEStore® is straightforward and carried out professionally by your own installer or one selected by us.

The operation of NEStore® is monitored remotely. Regular maintenance is unnecessary and will only be scheduled if needed. We guarantee 7 years of warranty on the insulation.

De impact van NEStore voor de familie van Steenwijck

Component

Berekening na installatie NEStore

Impact/jaar

1. Gasvervanging (tapwater)

300 m³ gas (= 30% van gasverbruik gaat naar douchen en warm water)
× €1,42 (incl. verhoogde belasting 2026).

€ 426

2. Effect van salderingsbescherming

Je gebruikt ~1.400 kWh (=40% - van 30% naar 70%) eigen stroom direct voor douchen en warm water. Je vermijdt dure inkoop (€0,30) en "verkoopverlies" (€0,06). Netto voordeel: €0,24/kWh.

€ 336

3. Vermeden terugleverkosten

Door hoger eigen verbruik (van 30% naar ~70%) betaalt u minder/geen vaste terugleverkosten aan de leverancier.

€ 100

TOTAAL BASIS (Vast contract)

€ 862 / jaar

Bonus: Slim laden (Dynamisch

Laden op negatieve/lage prijzen in als er weinig tot geen zon is

Terugverdientijd voor de familie van Steenwijck

• Investering E20: €6.600 (WinterZon Actie, incl. BTW, excl. installatie).
• Terugverdientijd: €6.600 / €862 = ~7 jaar (excl. installatiekosten).

💡 Zelf opgewekte en gebruikte stroom

‍Over stroom die mensen zelf opwekken en direct gebruiken, betalen ze geen belastingen. Ook betalen ze hierover geen kosten aan de energieleverancier. Direct zelf opgewekte elektriciteit gebruiken, zorgt daardoor voor een minder hoge energierekening. Daarnaast zorgt het voor minder druk op het elektriciteitsnet.

‍2. Energieprijzen & Belastingen 2026: Voor langetermijnrendement hanteren wij de adviesprijs van Milieu Centraal (€ 1,42/m³). Gebaseerd op actuele markttarieven van januari 2026 (€ 1,24 - € 1,33 per m³ gas) en de verhoogde energiebelasting op gas (€ 0,73 per m³).

‍3. Kosten Warm Tapwater: In een gemiddeld gezin gaat 20% tot 30% van het gasverbruik naar douchen en warm water (ca. 270-300 m³ per jaar). In goed geïsoleerde woningen loopt dit op tot 50% van de totale energierekening.

‍4. Verliezen Standaard Boilers: Uit rapportages van Topsector Energie/RVO blijkt dat conventionele boilers en warmtepompboilers dagelijks 20-40% energie verliezen door stilstand. NEStore reduceert dit tot <1% per dag.
