What is a Through The Wall Heat Pump?

These wall heat pumps do exactly what their name says. They are installed into your wall and instead of producing cold air, they produce heat. If you have a decent heat pump, it should be able to produce cold air as well as dehumidify and filter out any dust particles. They will also help circulate air to keep your home from becoming stuffy.

How Does a Through the Wall Heat Pump Work?

The heat pump transfers the heat energy from a heat source to a heat sink. The pump moves this thermal energy in the opposite direction of the spontaneous heat transfer by extracting heat from cold air and releasing it as warm air. Heat pumps are said to be four times more effective than the average household heater, even using the same energy. The only difference is that heating pumps are more expensive to install.

How to Choose The Perfect Model

Choosing the right heating pump is an important task. You’ll want to find a device that does its job properly without any hassle and contains the best features on the market. The following section will discuss the features or aspects to consider before buying your next heat pump.

BTU Rating​

The BTU rating is the amount of heat that’s necessary to raise the temperature of one pound of water by one degree. It stands for British Thermal Unit. However, the U.S. uses the same term for the metric system. The best way to understand this rating is that for every extra person after the first two, you should add an extra 750 BTUs.

Area Covered​

The amount of area that the heat can cover is also a huge factor you need to consider before buying. The absolute minimum your heat pump should cover is 150 sq ft. If your heat pump does less than this, it shouldn’t even cross your mind again. The average heat pump will be able to heat an area of around 450 sq ft or more.

Additional Features​

As we mentioned previously, these heat pumps are a lot like air conditioners in the fact they can produce cold air and hot air. Some top of the line heat pumps will be able to provide extra services such as a dehumidifier, air conditioner, and even act as a filter for any dust particles.

PROS

  • Dehumidifier
  • 350 Sq Ft of Heat
  • Top of the Line Filter
  • Multiple Installation Methods

CONS

  • Heavy and Loud
  • No Hose for the Dehumidifier

Our Review

This heat pump can provide you with both warm and cool air and allows you the ability to install your product via a cut out in the wall which would be more permanent or the alternative, which is through a window.

A window mount is also included in your kit. The device can also give you control over setting the temperature level. Not only that, but you can also control the different fan modes. The anti-bacterial filter also eliminates any particles or bad odors to create a healthier living environment. The dehumidifier can also absorb up to 1.5 pints of liquid each day.

Bottom Line

There are many benefits you can enjoy from this heat pump, it will be able to evenly distribute 350 sq ft of heat or cool air. The fact it provides cool air is another huge benefit. The filter is anti-bacterial and allows you to absorb any bad odors any dust particles which creates a safer environment for your family. Having the choice between the window or a permanent installation through the wall is another great advantage.

This product also offers the benefit of a dehumidifier which is a fantastic way to remove up to 1.5 pints of liquid each day. The only downside with this is that there isn’t a hose for the dehumidifier, meaning you have to manually empty the tank each time it fills. If you want something light, you’ll want to buy something else. This product can also become loud if you leave it running for a while. All in all, it’s a great product and deserves the top spot as the downsides are minor in comparison to the benefits.

  • Limited Installation
  • No Hose for the Dehumidifier

Our Review

Coming in as runner-up, this heat pump can churn out heat to your house and warm an area of 550 sq ft, an impressive amount and far more than the overall best heat pump. It features an energy efficiency ratio of 9.5. With plenty of features, this product can be controlled via remote control to change the speed of the fan, which has three different options to choose from.

The product also has four operation modes to play with. Additionally, the heat pump has a built-in dehumidifier that can capture up to 60 pints of water per day, which is also double what the previous product could take in. The remote control can also be used to customize the timer and sleep mode function that is helpful.

Bottom Line

Despite coming an as runner-up, this heat pump was a strong contender for best overall. The many benefits include the fact that it covers a large area of around 550sq ft. The energy efficiency is also far greater than the previous product, the same goes for the dehumidifier that is twice as effective.

The multiple modes and features offer an extensive service that can all be controlled via remote control. All of these benefits are great, however, the downsides come close behind. There is no window mount with the kit. The filter is also absent, leaving behind more dust particles and bad odors. The dehumidifier also needs to be cleaned out manually as there’s no hose.

PROS

  • Energy Efficient
  • Multiple Modes
  • Remote Control
  • Covers a Great Area

CONS

  • No Filter
  • No Dehumidifier

Our Review

Coming an as the second runner up, this heat pump can offer its owner an energy efficiency rating of an outstanding 11.2. It is able to heat an area of up to 320 sq ft, which is roughly the average area that is covered by these heat pumps.

The pump doesn’t just offer constant heat, but can also offer multiple cooling modes and fan speeds. This product is far smaller than the others mentioned and can be controlled via remote control. This remote control allows you to mess around with different settings such as the fan speed, timer, or even the temperature.

Bottom Line

This product offers a range of benefits such as being far more energy efficient than the others on this list. This efficiency can save you money in the long run. The area it covers is also decent, not great, but still offers a standard area coverage.

The multiple modes like the timer can be controlled via the remote control, which makes it far easier to operate than pressing all the buttons on the device. The only downsides to this product are that they don’t have a dehumidifier or filter, which is both big benefits in cleaning dust from the household air.

Bottom Line

The last on our list isn’t there as a reflection of the overall quality of the unit. Covering the average main room of a household, this product is easy to use with thanks to the remote control which can alter the many settings and modes built into the heat pump.

This unit excels by providing your house with heat, cool air, and a dehumidified environment as it can extract 1.8 pints per hour. The only downside to this product is that it doesn’t come with a window mount and has to be installed permanently through your wall which can be more tricky.
