Our HEART beats for renewable energy systems


ERZ Energietechnik GmbH has always focused on renewable energy systems and established itself as a full-range supplier for biomass systems and heat pumps – with state-of-the-art pellet and wood chip systems up to 1,500 kW, the wood gasification boilers up to 40 kW and the heat pumps up to 40 kW, HERZ offers a complete range of modern, cost-effective and environmentally friendly heating systems with the highest level of convenience and user-friendliness.

As an Austrian boiler and heat pump manufacturer, it gives us great pleasure to see numerous satisfied customers. Here are some examples:

St. Kathrein am Offenegg, Styria
Transforming old into new. The old heating plant Brandlucken of the biomass association St. Kathrein am Offenegg, which no longer meets the requirements, has replaced its old boiler with two modern and sustainable firematic wood chip boilers with 399 kW each. These now supply a natural hotel, other businesses and several private homes with environmentally friendly heat from HERZ.

Ebenthal, Carinthia
Family Schoby from Ebenthal in Carinthia enjoys their HERZ commotherm LW-A air heat pump with 13 kW on cold days. During the construction of the new building, the family decided, together with Herz partner plumber Thomas Scheck Heizung-Sanitär e.U., to install a heat pump system because their house meets the requirements for a low-temperature system.

Neckenmarkt, Burgenland
Nahwärme Neckenmarkt has been a customer of HERZ Energietechnik for many years. The supply of 150 objects has already been carried out for years with biomass systems from HERZ. To ensure that the supply continues to run smoothly in the future and meets the requirements, the local heating network was modernised. One of the three systems previously used has been exchanged and replaced with a HERZ BioFire 800 kW wood chip boiler, and the two existing systems were upgraded to the latest state-of-the-art. During the conversion work, care was taken to provide uninterrupted heat. The customers connected to the local heating network thus noticed nothing of the conversion and were continuously supplied with heat.

Draßmarkt, Burgenland
In the Draßmarkt region, the focus is on regionality and sustainability. Therefore, 160 households or 140 objects will be supplied with sustainable heat in the future. Thanks to the modern biomass plant BioFire with 1000 kW, which is operated by wood chips, limit values can be kept and additionally fuel costs and/or the fuel consumption can be saved.

St. Kathrein am Offenegg, Styria
The provision of sustainable heat is the primary goal of Nahwärme St. Kathrein am Offenegg. To ensure a sustainable and environmentally friendly heat supply, the local heating system in St. Kathrein am Offenegg was modernised. This was realized with the help of two HERZ BioFire 600 wood chip boilers, each with a double cyclone. As a result, the specified limit values can be undercut and the consumers can be supplied with sustainable heat.
