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?
In this article I present the Honeywell HR25 Energy electronic radiator thermostat. The article is part of the series “Electronic radiator thermostats in test”, in which I review and evaluate programmable radiator thermostats from various manufacturers.[Read more…] about Review: Radiator Thermostat Honeywell HR25 Energy
In this article, I present the Honeywell HR30 Comfort+, which does not have a Smart Home connection but is still one of the best electronic radiator controllers from Honeywell. This article is part of the series “Electronic radiator thermostats in review”, in which I test and evaluate electronic radiator thermostats from various manufacturers.[Read more…] about Review: Radiator Thermostat Honeywell HR30 Comfort+
In this article I have tested for you a solar system in a complete set and show you my experiences. I received the Autarkic S-Master 100W Solar System - 600W AC Output 12V 230V* from the company Offgridtec for testing, with which I would like to thank once again very much.[Read more…] about Review: Solar System Autarkic Complete Set from Offgridtec
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
