GNV – Erdwärmeprodukte & Geothermie

Distribution systems for tapping geothermal energy

So that you can complete your project as planned

Every construction site that cannot be completed costs time and money

You may be familiar with the situation: the building is finished, the holes for the necessary connections have been drilled. You have done your job reliably as always. But then your suppliers let you down. Manholes and materials are not delivered on time. This causes major problems that put you under enormous pressure.

We don't think that's necessary!

You can rely on everything going according to plan. At any time. At any location.

Fast production

Save time and nerves. We produce at short notice and individually.

Reliable delivery

You manage your project without stress because our service arrives on time and in the right place.

Our products

Geothermal heat distributor

The geothermal manifold is an important device for hydraulic balancing of the geothermal probe, for venting the system and for individual control of the probes.

Geothermal shafts

Shaft for installing the geothermal heat distributor outside the building. A shaft keeps condensation away from the building, provides easy access for tradesmen and replaces a boiler room.

Well shafts

Our well shafts made of plastic shafts are significantly lighter, do not require complex core drilling, have prefabricated connections and can be installed quickly. These are advantages that conventional concrete rings do not have.

Ice storage systems & energy fences

We can offer our ice storage systems and energy fences in all variants thanks to our high level of automation.

Unsere Produkte

Erdwärmeverteiler

Der Erdwärmeverteiler als eine wichtige Vorrichtung zum hydraulischen Abgleich der Erdwärmesonde, zum Entlüften der Anlage und zur einzelnen Steuerung der Sonden.

Erdwärmeschächte

Schacht zur Montage des Erdwärmeverteilers außerhalb des Gebäudes. Ein Schacht hält Schwitzwasser vom Gebäude ab, bieten einen leichten Zugriff für Handwerker und ersetzt einen Heizungskeller.

Brunnenschächte

Unsere Brunnenschächte aus Kunststoffschächten sind deutlich leichter, benötigen keine aufwendigen Kernbohrungen, besitzen vorkonfektionierte Anschlüsse und können schnell installiert werden. Dies sind Vorteile, die konventionelle Betonringe nicht haben.

Eisspeichersysteme & Energiezäune

Wir können unsere Eisspeichersysteme und Energiezäune durch unsere hochgradige Automatisierung in allen Varianten anbieten.

Technisches Zubehör

Hochwertiges Zubehör ist entscheidend für den erfolgreichen Betrieb von Erdwärmeanlagen. Bei uns finden Sie alles, was Sie zur Gewinnung von oberflächennaher geothermischer Energie benötigen.

What sets us apart from others

We know that everything has to go according to plan when developing geothermal energy. The right distribution shafts and fittings must always be on site when they are needed. Unfortunately, the reality is often different: Long production and delivery times for geothermal components mean that most construction projects cannot be completed on time and pressure builds up.

That's how many of our customers used to feel.

That’s how many of our customers used to feel. We think it must be easy to make geothermal energy accessible as an energy source. And we understand how important it is for you to be able to rely on suppliers. That’s why we make sure that our distribution shafts and systems are always on site when they are needed. We now have over 400 customers who trust us as a reliable supplier of geothermal shafts and ice storage systems. Give us a call right away. You will no longer have to worry about unreliable suppliers and late deliveries. Instead, you will have your materials when you need them and can be sure that everything will go according to plan.
