Why does the gas-fired hot water boiler have the problem of slow heating?

18 Mar 2022

1. Because gas hot water heating boiler is used for central heating, after the boiler is ignited during heating, a series of processes such as furnace heating, low-temperature operation and heat exchange are needed, to gradually heat up the central heating. After ignition of gas-fired hot water heating boiler, furnace heating is a necessary preparation work at the initial stage of heating every year, and this process takes about 3-5 days to complete.

2. In the process of use, the gas-fired hot water heating boiler also needs to undergo the process of heat exchange, so that the temperature can gradually rise. The heat exchange process of gas-fired hot water heating boiler is mainly the process of water circulation. The hot water from the heating station is not directly circulated to the heating pipe network of residents' homes, but needs the heat exchanger unit to transfer the heat energy of the hot water in the heating station to the circulating pipe network of residents' homes.

3. At the initial stage of boiler heating start-up, the outlet water temperature of each heating station is not very high, and the structure of the pipe network is complicated, so the hot water heat exchange of gas-fired hot water heating boiler needs a process, especially for users at the end of the pipe network, the process time of heat exchange will be longer.
