Heating system provides comfort and warmth in buildings during the cold season. Since heating is a very complex system, you will find many interesting articles on heating and energy systems in this category. From hydraulic balancing, heat generation, heat distribution and heat emission to legal obligations and regulations, there have already been many and detailed articles about heating technology. I will continue to develop these, in order to offer you a comprehensive overview of heating technology. In the following the articles published so far are once again clearly listed:

Hydronic balancing

Heat generation

Heat Distribution

Heat Transfer

Hydronic Balancing DIY – Step 1: Fundamentals

Last updated on By Leave a Comment

Hydronic balancing is the bugbear for many craftsmen and it is often claimed that hydronic balancing in existing buildings is not worthwhile.
The main argument: all the data needed for the calculation is missing. However, there is good news: The simplified calculation method for hydronic balancing is based on assumptions, and convinces with excellent results.

In this series you will learn how to do a hydronic balancing yourself using the simplified calculation method and reduce your heating bill by up to 13 %.

How does a gravity hot water heating system work?

Last updated on By Leave a Comment

In this article I will introduce you to gravity hot water heating. Gravity hot water heating is a heating system based on the physical principle of gravity and works due to the change in density of water. Thus, gravity heating does not require electrical energy for a circulating pump (as in a heating system with circulating pump) and works solely based on the physical properties of water.

Design of a central heating pump with example calculation

Last updated on By Leave a Comment

In this article I will show you how to calculate and design a central heating pump (circulating pump) with only few data. This calculation method is mostly used in existing buildings, because technical data is hard to find or not available at all. In a small example calculation I show you that the calculation of a heating pump is easier than you think. Afterwards we will design a central heating pump using the example and choose the right model for our application.

What is pump head and why it’s important?

Last updated on By Leave a Comment

The head of a heating pump is not as easily explained in one sentence as you might think – or maybe it is? Here is a definition attempt from Wikipedia:

“In fluid dynamics, Total Dynamic Head (TDH) is the total equivalent height that a fluid is to be pumped, taking into account friction losses in the pipe.” Total dynamic head – Wikipedia

I think this definition is a bit confusing and therefore I would like to explain the term “head” for pumps a bit easier.
