Heat smart and save costs with HERZ
Efficient heating starts with a simple but often overlooked measure: hydraulic balancing. Particularly in renovation projects, hydraulic balancing has the potential to significantly reduce heating costs, save energy and increase living comfort.
HERZ Taps
A balance between acceptance and innovationKitchen and bathroom taps are elements of every home that have to meet the daily demands of all of us. Every day, they accompany us in the small but essential rituals – from washing our hands in the morning to cooking in the evening.
We move water 2.0
HERZ Pumpfix AccessoriesEvery system, without exception, has fixed components that it cannot function without. However, putting the individual parts together takes a lot of time and space, both in the planning and in the implementation.
HERZ HIU Compact
Modern heating systems have to fulfil a wide range of requirements – from different flow temperatures for radiators or surface heating systems to various tapping capacities. In addition, there is often limited space and the challenge of a smooth installation.
Save Money with HERZ
In Vienna's 18th district, a four-storey apartment in a family-owned period building is currently being converted to a more efficient energy supply with district heating.The decision was not only based on ecological considerations, but also on the attractive funding opportunities offered by the ongoing ‘Raus aus Öl und Gas’ (Out of Oil and Gas) campaign
Floor manifold
The guide to optimal heat distributionHERZ floor manifold offer direct and easy access to all important components, such as heat meters and regulating and isolating valves, without having to rely on the presence of the occupants.
HERZ MINI thermostatic heads
Suitable for every radiatorThe major influence of the thermostatic head on energy-efficient heating is greatly underestimated. The correct use of the thermostatic head ensures a regulated and efficient heating system and helps to save costs, as well as providing a sense of well-being in the room.
At the peak of dynamics
HERZ Pressure independent control valvesDynamic valves ensure efficient and controlled distribution of the heating medium in a heating system. Regardless of whether it is a full or partial load range, each part of the system is supplied with the required amount of energy at all times thanks to the use of dynamic valves.
ÜA-mark: Drinking water is our gold
Clean, hygienically safe drinking water is one of the most valuable resources of our time and must be particularly well protected. Laws, ordinances and regulations define the detailed framework conditions for protecting the blue gold from harmful influences

We pull all pulling together
HERZ balancing valvesIn the world of heating and cooling systems, the interaction of various components is crucial to ensure smooth and efficient operation. The multitude of pipes and valves in these systems with different consumers requires precise regulation to achieve the desired temperature and performance.
We move water
HERZ PumpfixPumps play a central role in heating and cooling systems. They ensure that the water is transported from the heat source to the radiators or panel heating systems.
Heat in the right place at the right time HERZ dynamic control set
Even though the start of the winter season creates a lovely Christmas atmosphere, it also marks the official opening of the heating season. However, rising heating costs do not make us feel warm inside.
Heat and efficiency combined HERZ district heating transfer station
HERZ district heating transfer stations play a central role in the efficient distribution of heat in residential and industrial buildings.
