How to use solar water heater for indoor heating in winter

Winter heating mode, when starting the gas wall-hung boiler, the gas wall-hung boiler first water, air safety testing, after testing to meet the operating conditions, start the heat converter circulating pump to extract high-temperature water tank hot water, when the heat converter temperature sensor detects the solar high-temperature thermal storage tank temperature is higher than 70 degrees, the start of the wall-hung boiler circulating pump for heat exchange, the exchange of 4 minutes after the temperature does not reach the set heating water supply temperature, open the gas ratio valve for secondary heating until it reaches the set heating temperature, the second cycle takes 4 minutes, the wall-hung boiler detects the heating return. When the temperature does not reach the set heating water supply temperature, open the gas ratio valve for secondary heating until it reaches the set heating temperature, the second cycle takes 4 minutes after the wall-hung boiler detects that the heating return temperature is lower than the set temperature of 75% of the following when the heat converter is started again for heat exchange. If the water tank temperature is lower than 70 degrees will not be converted to ensure the use of domestic hot water. Living hot water mode is to open the hot water faucet, cold water first into the converter, the converter heat exchange into the gas wall-hung boiler, when the wall-hung boiler to monitor the temperature is higher than the set, the wall-hung boiler standby, lower than the set temperature when the gas wall-hung boiler to start the second heating to ensure that it reaches the set temperature.
