Have you ever had your heat pump frozen completely? Luckily, the issue can be easy to be spotted, in most cases, easy to manage as well! Trust the specialists at Zeaux to bring you the answers you need!
The operation of a pool heat pump is similar to that of an air-source heat pump frozen in winter which is very common.
In this, the condenser transfers the heat to the cold water. The other processes are similar to the room heat pump. Hence, the condenser is immersed inside the pool and the remaining unit is outside the pool.
Most reasons for heat pump frozen vary from weather-related reasons to internal causes. It is a very common question asked by first-time swimming pool heat pump owners, more often by those living in colder climates.
The Question Why Is My Unit Covered In Ice?
The answer is not only what causes this ice formation, but also how to prevent it from damaging your unit. If you are having trouble with your pool heat pump frozen, it usually means a serious problem that should be solved by an HVAC professional (refrigeration technician). If left unrepaired, the drive could suffer even more damage and eventually break permanently.
In order to explain how ice forms on a pool heater, we first need to clarify two points of an INVERBOOST pool heat pump operation:
Firstly, when a heat pump runs, its evaporator coil constantly rises and drops in temperature as the refrigerant inside it collects and releases heat. When it falls in temperature, condensate water forms on it. In fact, a pool heater typically produces about one gallon of condensate water per hour of operation.
Secondly, when air flows through a pool heater, it passes over the evaporator coil and drops in temperature by 5° to 10°C, as its heat is collected by the evaporator coil’s refrigerant.
So, when the air below 10°C passes through your heat pump, it can cool to below 0°C and freeze the condensate water on the evaporator coil.
To solve the defrost problems on INVERBOOST pool heat pumps. If the pool heater is completely covered with frost or ice, you are suggested to switch off the system and call for licensed technicians.
Troubleshooting of heat pump frozen suddenly
Actually, there are a few steps you can take before reaching this point :
- Check the unit’s air filter to make sure it is not clogged or damaged. Replace dirty filters.
- Check the internal vents and logs to make sure they are not blocked by boxes, furniture, clothes, or other objects.
- Eliminates the buildup of leaves, grass, sticks, snow, dirt, or other material that could interfere with the unit’s airflow or block the external coil.
- Check that overflowing gutters do not drip onto the outdoor unit.
- Schedule the maintenance check once a year
Do not let your pool heat pump suffer the consequences of ignorance while you can take measures to prevent it. This article has provided readers with the most common reasons why a pool heat pump frozen and ways to avoid or fix the issues.
