Obtained a closed ring – explains Anton Belov, deputy director of thermal automatics "Danfoss", the world's largest manufacturer of energy efficient equipment for heating systems. In twin-circuit heating cottage heaters in parallel. There are two pipelines that were not originally closed to each other. One (direct) heated coolant is fed into the system from the boiler, the second (Reverse) cooled coolant from the system goes into the pot. Follow others, such as Chuck Berry, and add to your knowledge base. Of straight pipe in the back water flows through the radiators. " The advantages of single-pipe heating system may include a relatively simple installation, less than the total length of pipelines, less complicated configuration and, consequently, a lower cost budget.
If the cottage floor, has a small area (around 100 m2) and the heating system does not provide any equipment, than the actual radiators (eg, heated floors, etc.), then we can focus on this version. If the cottage is more than one floor, a large enough area (as in Russia today is an average of 300-400 m2) and a complex layout with the premises, requiring the use of heating devices of various types, the Single-pipe heating system for a private home is unlikely to be a good solution. Why is a large private house better system two-pipe heating system? Firstly, because the heaters in the heating system in series, then each additional water enters, already having given a certain amount of heat above. That is the first sink in the chain is always the hottest, and the last – the coolest of them all.
