How to Protect your Residential Heat Pump From Snow And Ice
As summer passed, the weather began to change. Owners who bought residential heat pump should begin to prepare for more extreme and unpredictable weather in winter. In the north, if there is no heating system, the cold winter will bring discomfort to you and your family.
However, ice and snow weather may also have an adverse impact on your home heat pump system. It is important to be vigilant about the methods of protecting heat pumps.
For home heat pump maintain, you need to prevent weather related damage in winter or even spring. In winter, you risk being blocked by ice and snow. Although the heat pump for house itself has automatic defrosting function, frequent defrosting will reduce the running time of home heat pump. And in extreme snow and ice weather. If the ice and snow coverage speed exceeds the defrosting speed, you need to defrost manually.
When ice and snow block the air flow between the heat pump and outdoor air, it will reduce the energy efficiency of the system and may even cause irreparable damage to the equipment. Although a thin layer of frost is completely normal, a large amount of ice and snow needs to be treated.
After every snowstorm, you should check the surroundings of your house. If you have a gas stove, make sure your intake and exhaust pipes are free and clean. If your pipe is blocked, this may cause combustion gas to leak into the house and the system to shut down.
The residential heat pump processes the average amount of ice by using its automatic defrosting system and switching to heat distribution mode. This cycle usually lasts about 15 minutes. The working principle is to return the hot refrigerant to the outdoor residential heat pump to melt the ice and snow (similar to the working principle of the heat pump in summer). You may notice some cold air coming out of your vent while the unit is undergoing a defrosting cycle. This is normal. Just wait 10-15 minutes.
In some devices, electric heating is started, which is called auxiliary heating. If the heat pump for house does not resume operation after the defrosting cycle, you will continue to use "emergency heat" or "auxiliary heat". If your heat pump for house doesn't work, emergency heating may let you spend a comfortable night, but you will want to call a professional technician to solve the root cause as soon as possible. If you ignore this problem and continue to use emergency heating, you will be ready to pay the sky high electricity bill.
