The north has entered a severe winter. In order to better use the air energy water heater heating system, it is recommended to do a good job in winter antifreeze. In order to ensure the normal use and safety of heat pump system equipment, and avoid freezing damage to the heating system due to water shortage, improper operation or use, remember to understand these antifreeze knowledge.

Pipe insulation

When the ambient air temperature reaches the freezing point, the water temperature of the air energy water heater drops rapidly. If no insulation measures are taken for the hot water pipes and return pipes, the heat consumption will be accelerated. The air energy water heater pipes are mainly insulated with insulation cotton or polyurethane foam. Small pipes are generally insulated with insulation cotton, while large pipes are insulated with polyurethane foam.

Drain the heat pump unit when not in use

If the air energy water heater unit does not operate in winter or needs to be shut down for a long time, such as frequent power outages, unit shutdowns at night, winter holidays, and unit infrequent use in winter, the unit, water pump, and outdoor pipeline should be drained to prevent the unit from freezing, and the power supply should be cut off and the protective cover should be put on. When running again, please check the system thoroughly before starting.

Keep the heat pump unit energized during use

Keeping the unit energized in winter can not only ensure that the air energy water heater can provide hot water all day long, and the compressor can be started frequently, but also ensure that the unit will not frost, so that the unit can operate normally. The air energy water heater water heater and heating unit will start the automatic antifreeze protection function when the outdoor temperature is low in winter.

Add antifreeze when it is inconvenient for the unit to drain water

According to its own use situation, in winter when it is not convenient for the unit to drain water, but it is possible to cut off water and power, the air energy water heater heating system needs to add antifreeze, and the antifreeze must be selected according to the local minimum temperature as an important parameter.

Icing treatment

If the pipe of the air energy water heater has frozen but has not cracked, remember not to knock on the pipe or pour hot water on it, and wait for the ice on it to melt naturally.

The anti freezing of heat pump unit shall ensure the safety of hot water and heating system, and prevent the heat pump system from freezing and causing unnecessary losses due to power failure, water shortage, improper operation or use.
