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.[Read more…] about How does a gravity hot water heating system work?
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 small article I will introduce you to the heat flow rate, also called heat performance, as another basic and important quantity of heating technology. The heat flow rate is given as (Q point).[Read more…] about Heat Flow Rate – Performance in Heating Technology
Today I would like to introduce the specific heat capacity to you in a slightly smaller article. The specific heat capacity indicates the quantity of heat that a substance can release or absorb in relation to its mass when the temperature changes. The temperature change is given as temperature difference in Kelvin .[Read more…] about What is Specific Heat Capacity?
