The cleaning of scale and impurities is very important. The scale and impurities in the water pipeline will directly affect the heat exchange efficiency and life of the gas wall-hung boiler. Therefore, acidic water is a very good and effective way to remove scale.

　　When we need domestic water in summer, we turn on the faucet, and the gas wall-hung boiler will automatically ignite. The circulating pump drives the hot water in the main circuit of the wall-hung boiler to circulate between the main heat exchanger and the auxiliary heat exchanger, and the auxiliary heat exchanger transfers the heat energy from the closed circulation water circuit to the imported cold water. The maximum water temperature of domestic hot water is lower than 64°C, which can prevent the formation of scale.

　　The floor heating system and radiator replacement water also need to be paid attention to. After the radiator comes out, debris and other impurities will remain due to transportation and other reasons. Over time, the fusion of scale and so on will affect the heat dissipation effect of the radiator.
