An air to water heat pump is a device that extracts heat from the air, as a way to heat the water in a boiler. This type of device is fairly simple, and includes filters to prevent dust and other impurities from harming the heating and cooling system. The air to water heat pump pulls the air from outside the home and the compressor inside then moves this air through the water tank. The heat from the air transfers to the the water in the tank. Over time, like any heat pump, the air to water heat pump may need to be removed and replaced. Doing so is more or less removing the compressor, which is the main device of the air to water heat pump. The article that follows will explain how to remove the air to water heat pump and then replace it.

Step 1 – Safety

In order to remove the air to water heat pump, you need to make sure that it is turned off. At the main circuit box in your home, open the panel and look for the correct switch. It will usually be the hot water heater, basement or boiler switch. Turn it off. You will know the air to water heat pump is off, because it will not be vibrating or making any noise.

Step 2 – Remove the Air to Water Heat Pump

The heat pump in question is attached to the water heater. It is a box that is separate from the water heater. It can be on the ground, but it can also be located near the ceiling. There will be pipes attached to it from below. The compressor is inside the enclosure. You can replace the entire pump, or just the compressor. Make a note of where each of the pipes goes, so you can have an easier time replacing them later. Use the wrench to carefully disconnect the pipes from the air to water heat pump. Place the pipes off to the side. Hold the pump while you removing the pipes, so it does not fall.

Step 3 – Remove the Compressor

If you are removing only the compressor, you still need to disconnect the pipes. Write down where the wires inside connect. Use the screwdriver to loosen the contact screws, and then remove the wires. You can now remove the compressor. These can be very heavy, so you may need to enlist the help of some friends to remove it.

Step 4 – Place the New Pump

Installing the new air to water heat pump is simple. Use the diagram you drew, and set the new pump in place. Connect the pipes and tighten them with the wrench. If you removed only the compressor, then place the compressor inside the enclosure and replace the pipes. Connect the wires the same way as they were previously. The wires are simply installed by wrapping the ends around the screw contacts. Tighten the screws.
