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.

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
Force of Action
Heat Transfer
Design of a central heating pump with example calculation
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.

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.

In this article I will explain to you how a thermostat, which is also called a thermostatic valve or thermostatic radiator valve, works, is constructed and what the differences are between conventional and electronic thermostats.
Important: However, first of all, it is necessary to make a differentiation for the term “thermostatic valve”, because a thermostatic valve consists of two components: the thermostatic head and the radiator valve.

In this article I will explain what hydronic balancing is and which steps are necessary to balance a heating system. For the term hydronic balancing the term hydraulic balancing is often used. Hydraulic balancing is relatively simple.
