The cost of ready-heating systems (turnkey) is $ 20-50 per 1 m2. Do not forget to check with the company a license for the right design, the list of contents and test all systems and 九五彩票app下载 warranty conditions commitments in the construction contract. The system consists of a water heating boiler (heat generator), piping, heaters, control and regulating and shutoff valves. For each of these components offer their products at least a dozen firms. The difficulty of selecting elements of the system lies in the fact that the search should not the best or cheapest items, and those assembled reliably provide a warm 九五彩票app下载 and will be reasonable to value. The most reliable selection criteria, unfortunately, there are practice and feedback from experienced professionals (which always tells the magazine in its pages).
Our advice: purchase parts from one manufacturer's instructions. In this case, we can expect that the manufacturer of a wide range of system components created on the basis of their compatibility. For firms that offer in our market a complete set of components for heating and water supply can be attributed such as OVENTROP, REHAU, AQUATHERM (Germany), HERZ (Austria), HONEYWELL (USA), etc. Let's see what it depends on the quality of the heating systems. Heating system is simple and robust system with a natural circulation of coolant (water, antifreeze). This circulation is due to the difference densities in the flow of hot water standpipe and water, chilled in the devices and the return line. The main advantage of such a system is that there are no electrical devices, designed for forced circulation of coolant.
