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.[Read more…] about Design of a central heating pump with example calculation
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:
Force of Action
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.[Read more…] about What is pump head and why it’s important?
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.[Read more…] about How do Thermostatic Radiator Valves Work?
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.[Read more…] about What is hydronic balancing?
In this short article I explain what a heating system with circulating pump is, how it works and what its advantages and disadvantages are. The most important feature of a heating system with circulating pump is the use of a pump to transport water in the heating system. An alternative heating system is gravity heating.
Heating system with circulating pump
In a heating system with circulating pump, the heating water is forced to circulate in a heating circuit with the help of a circulation pump. The circulation pump can be installed in the flow pipe (FP) or in the return pipe (RP). However, it has become generally accepted to install the pump in the flow pipe. If you can’t imagine a circulating pump, you will find a modern circulation pump in Fig. 1.[Read more…] about How does a heating system with circulating pump work?
