Hydronic theory

We know a thing or two about Hydronic Engineering. Here is where you can learn the theory behind what we do best.  ​

Yes, we make GREAT products that help to create superb HVAC Solutions, but it has taken decades of extensive research and innovation to get us where we are today and we want to share that knowledge with you.  

Discover all you need to know for optimised HVAC systems

We’ve developed an extensive database of technical articles and information about the theory behind our Hydronic Engineering products and solutions that we’re happy to share with you here. So take a look around – we’re sure you’ll discover everything you need to know to deliver energy-efficient, balanced and optimised HVAC solutions.  ​If you’re keen to find out more, the resources below will go a long way towards helping you gain control at every turn and optimising HVAC systems for peak performance.​

Desired indoor climates at the lowest possible energy cost

​​To obtain the desired indoor climate at the lowest possible energy cost three conditions must be fulfilled. 

Solutions for the balancing and control of small terminal units

At IMI Hydronic Engineering, we believe in always using the right tool for the job. That is why we provide several solutions for balancing and control of small terminal units.

The Compensated Method

The Compensated Method is a further development of the Proportional Method, with three main advantages. 

Balancing of Domestic Hot Water Systems

​​​​​In domestic hot water distribution, temperature of water in the pipes drops significantly when consumption is low or zero. As a result, people get disappointed to wait so long time t...

Dividing a hydronic system in modules

In theory, it is sufficient with one balancing valve per terminal unit to create the correct repartition of flows in the distribution system. But this requires that the preset value for a...

Balancing of typical systems

Balancing of hydronic plants requires some specific conditions that will be analysed bases on some examples.

Balancing Protocol

The aim of balancing is to apply adjustment of flow rates to achieve design requirements

Hydronic balancing & stabilisation of the differential pressures​

The main objective of heating and air conditioning plant design is to obtain a comfortable indoor climate, at minimal energy costs and without operational problems.

The TA Balance Method

The TA Balance Method is a computer program built in the balancing instrument CBIII​​ with the same three main advantages of the Compensated Method plus the possibility for one man and on...

Optimizing hydronic distributions for energy efficiency

​​​​​We present the technical article, based on the scientific work, written by Jean-Christophe Carette, Director of Hydronic College and Eric Bernadou, Senior Marketing Manager. 

Flows must be compatible at system interfaces

Well-designed HVAC plants deliver comfortable and efficient indoor climates at minimal operating costs
