It’s very common for heat pumps to ice over in the winter time in Newcastle. It can be due to freezing temperatures and icing outside or it could be due to constant running of the heat pump or excess moisture on the coils. However, while a bit of ice on the heat pump is relatively normal, the entire unit should never be covered in ice – such a thing is not only hard on the machinery; it can result in no heat for your home.
How to Handle Ice and Snow on the Heat Pump
Should your heat pump become covered in ice or snow in the winter time, there are a few things you can do and some things you should not do. First, check to make sure the problem isn’t related to a broken defrost cycle timer. The heat pump should go into a defrost cycle every 30-90 minutes to keep excess ice from building up. If this doesn’t happen, it should be inspected for a thermostat or sensor problem.
To actually remove the ice from the unit, never use a sharp object to pick the ice clear. You can easily damage the coils or another part of the unit and leave it permanently broken. The best way to remove ice from your heat pump is to rinse it off with a hose – even cold water will remove ice. Just be sure the defrost cycle is ready to come back on so the water used to rinse away the ice doesn’t freeze.
Remember to check your emergency heating source and make sure it is switched on while this is happening. Your heat pump likely won’t work properly while iced over and if it is left in the on position, excess stress on the device will cause damage.
To avoid this kind of damage, turn off the heat pump and turn on your emergency heating source, then clear away the ice and check the defrost timer. If everything works properly, turn the heat pump back on, but if you find any problems, call a professional to do a more thorough inspection of the device before you use it again.
