After the gas boiler heating system long working hours , the phenomenon of water loss will occur , so the boiler should pay within a reasonable time , then how gas boiler should pay ? Conventional point of view, nothing more than water filled into the new water , but did not pay attention if the gas boiler method , the result is a great difference.

Today are two kinds of heating systems, floor heating systems and high-end conventional radiator heating systems. The warm water is: first open the exhaust valve and all valves on the manifold , and then need to open the water valve on the gas boiler in the replenishment process, we need to observe the exhaust valve , drain valve if there is water outflow , if water overflows , it means that the water heating system has been filled, it can be turned off when the exhaust valve ; pressure gauge and then see if the pointer to 1.5 , when you can turn off the water valve .

Methods radiator with water to warm different , we must first exhaust valve opens and the radiator thermostatic valve at both ends , and then also open the water valve gas boiler water . Radiator water is too much trouble , to see whether the fill vent , here is a look at the past , and the technique is a little lower section of the radiator , when filled with water after the rest of the exhaust valve as long as there water out of the exhaust valve can be closed . The same pressure gauge when to go to 1.5 and then close the water inlet valve .

Two replenishment methods are roughly the same, but because of the difference in heating systems and heating as well as a great film , therefore , we have to carry out water -related knowledge.
