In frosty nights many owners will rely on heat pumps to keep their homes comfortably warm.
When operating properly, air conditioning systems with a heat pump are a convenient and efficient source of thermostatically controlled heating.
Yet sometimes, just when you need them, heat pumps can fail. Here are just some of the ways things can go wrong.
* Has it been said that it is better to leave the heat pump all the time?
* How to heat your home this winter
* The heating errors you can make (and how to fix them)
* How to choose the best type of heater for your home
The heat pump simply does not respond
It frosts out and you want to increase the heat inside, but nothing happens when you touch the heat button on the remote control of your heat pump.
The heat pump works, but it does not seem to listen. This comprehensive scenario can quickly trigger panic … but do not worry because your chances are not just to fail catastrophically, but the adjustment is extremely simple.
Stephen Groufsky, manager of Hartnell Coolheat North Canterbury, suggests that a battery problem is more likely. "If your heat pump does not do what you want, or if you notice that the remote control display becomes weaker and weaker, the first thing you need to do is replace the batteries. [usually two triple As]If the batteries are standing up, this means that the remote control may not be able to send a signal to the heat pump. Believe it or not, this is the most common problem we face.
To avoid panic in the middle ofwinter, Consider changing the batteries of the remote control at least once a year.
Another Groufsky's suggestion is not to hold the buttons randomly if you think your heat pump is not responding properly. "This will probably return to the default mode … just hit the button once and give the device time to react. The best thing to do is put it in a fan with an auto fan set it to your desired temperature – then leave it alone.
PUMP WAS ONLY TO THE MOUNTAIN
Famed for many will be trying to get into a cold cold morning just to find that the heat pump blows cold air.
Strangely enough, the chilly morning may be a bit like cryptonite for heat pumps. As the temperature falls, it becomes more difficult for the external bodies to extract heat from the outside air and eventually they just freeze. The hot air flow will stop for a few minutes until the appliance self-frosts (this explains why water can sometimes be seen coming from the bottom of the outdoor units in a cold morning, this is part of the thawing process).
2017 Appliance Reliability Test conducted by Consumer have found that eight percent of its members have reported that heat pumps do not function adequately in cold and frosty mornings. (Heat pumps designed for heating up to -15 ° C will perform better in these conditions, the system must be properly dimensioned for the room).
Sometimes the leaves can accumulate behind the outdoor unit, making it more prone to ice. It is definitely worth taking a few minutes to check if the outdoor unit is clear. Ideally, there should be at least a meter distance between the front of the outdoor unit and the garden vegetation.
Dirty heat pump filters in your home can also reduce heating efficiency by blocking airflow to the air heater. Groufsky recommends regular cleaning of these filters with dust, soft brush or sponge, hot water and detergent.
THERMAL PUMP STOPS
Some people prefer to let their heat pumps work constantly instead of turning them on and off.
Yet, from time to time, they will stop moving without any obvious reason, perhaps because of a strong collapse or a slight thermostat defect.
According to Groufsky, the best option under these circumstances is to disconnect the isolator switch from the outdoor unit, wait a few minutes, and then turn it on again. This will restart the device and will generally correct the problem.
Professionals recommend checking and servicing the heat pump every few years to maintain the best possible condition.
