Do you have a suitable place to put it?

You need to install the device outside the house. You can hang it on the wall or put it on the floor near the house. You need to make sure you have enough space around the heat pump to realize good ventilation.

How will you heat your rooms?

Most French homes use radiators or under-floor heating to distribute heat to each room. The UK is a little different. While offices may use ducted heating, most homes use boilers to heat the water. Then they move the hot water around the house to heat the radiators. One of the advantages of air-to-air heat pumps is that they do not require a boiler to heat the house. Air-to-air heat pumps use fan coils/blowers to heat. Blowers are usually installed high in the wall and are suitable for homes with limited wall space. Ducts are commonly used in newer homes because they are often installed in ceiling voids to avoid damage. Air-to-air heat pumps can have one indoor fan or multiple fans. A heat pump with only one indoor fan is called a single-seal heat pump. A multi-seal heat pump has an outdoor unit and multiple interior fans. In general, single-seal air-to-air heat pumps only heat small homes or rooms. You may need a multi-seal air-to-air heat pump or a ducted system if you have more than two rooms. You can install an air-to-air single fan system quickly and cheaply. A multi-seal unit requires a pipe from an external heat capture device to each fan. Typically, these pipes run in long plastic tubes at the edges above the room to make them as invisible as possible.

How do you heat your water?

An air-to-air heat pump can cool and heat your room but doesn't provide hot water. Therefore, you need an alternative unit to heat water for your showers, baths, and faucets. Choosing the right type of heating depends on how much hot water you need for your home and house space or budget. You may consider an electric immersion heater, shower, or a "point-of-use" heater. Point-of-use" heaters can heat water with gas, liquefied petroleum gas, or electricity. Gas heaters require a chimney, while you can install your heaters in an inconspicuous spot under the sink.

Can an air-to-air heat pump help me save money?

Whether an air-to-air heat pump will save you money on your energy bills depends on the design and operation of the heat pump and the system you are replacing. Saving money is not everyone's primary motivation for installing a new heating system, but you need to ensure that installing the system is affordable. You had better ask your installer for a quote on the heat pump operating costs.

Installation and positioning of blowers/fan coils

The fan coils/blowers are connected to the external unit via ducting. They are typically installed inside the exterior wall near the outside unit to reduce the interior required duct length. When planning a multi-fan system, installers often try to minimize the length of ducting to each fan location. You can ask the installer about possible ducting routes before they begin work.

Installation of ductwork

Duct systems are often used in very energy-efficient houses. Some types of duct systems are called exhaust air heat pumps (EAHPs). Duct systems may not be well suited for older or larger houses with higher heating needs. The long, thin duct design allows a large amount of air to move through the house. You can hide these ducts in ceiling gaps. All visible from each room are two grid grilles mounted in the ceiling, one for inflow into the room and one for outflow. The air is heated in an air handling unit about the size of a boiler, usually installed in the attic or utility room.

What are Air to Water Heat Pumps？

——

Air-to-air heat pumps absorb heat from the outside air and transfer it to the air in your home, raising the air temperature in each room through a series of fan coils.

An air-to-air heat pump can either warm your house in the winter or keep it cool and comfortable in the summer like an air conditioner.
But air-to-air heat pumps cannot provide hot water for your house.
Therefore, you need to consider adding equipment to provide hot water faucets and showers for your home.

Are Air to Water Heat Pump Right for Me？

——

There are many aspects to consider before purchasing air-to-air heat pumps.

First you need to consider the size of the heat pumps and your home. Choosing the right size heat pump according to your house is very important. Too big heat pumps are not energy efficient and expensive in terms of electric bills. Small heat pumps are not good for your heat pumps and will not heat or cool your home properly.

Second, you need to consider the installation site and cost. Make sure you have enough outdoor area to put your heat pump units and allow the warm air to circulate timely. And the installation cost is also one thing you should pay attention to because it will affect your budget.

Lastly, it would be best if you also keep in mind the heat pump efficiency, noise level, cooling and heating capacity, and comfort. These are things that will decide your comfort and room temperature.

Air-To-Air VS Air-To-Water Heat Pumps

Air-to-water heat pumps

Air-to-water heat pumps may be the best choice if you need a unit that can heat your radiators. These heat pumps absorb heat from the outside air and transport the heat through pipes to water, then heat your radiators. Even when the temperature drops to -15 degrees Celsius, they can absorb low-temperature heat from the outside air to heat your radiators. As a result, air-to-water heat pumps are very energy-efficient and cost-effective. These heat pumps are up to 350% more efficient than fossil fuel boilers. Therefore, air-to-water heat pumps are a sustainable heating solution to heat your home!

Air-to-air heat pumps

Air-to-air heat pumps can heat and cool your house. These units absorb heat from the outside air. They then use a small amount of electricity to turn the low-temperature, low-pressure refrigerant gas into a high-temperature, high-pressure gas by using a compressor to do the work. The heat energy from the high temperature and high-pressure gas is then released into your home, providing you with heat. Unlike air-to-water heat pumps, which require radiators or underfloor heating, air-to-air heat pumps provide direct heating and cooling.

Compared to air-to-water heat pumps, air-to-air heat pumps are quicker to install because you don't have to make additional changes to your house. Air-to-air heat pumps can even work with your current heating system, giving you more options for temperature control. However, you will still need space for a stand-alone hot water system and an indoor unit.

Which is better?

Like everything has two sides, air-to-water heat pumps and air-to-air heat pumps are no exception. There is no such saying as which is the better choice: both have advantages and disadvantages. We need careful consideration before buying.

The type of heat pump you choose depends largely on your existing heating system and the heating effect you would like to include.

These heat pumps are highly efficient and are a sustainable heating solution, so they may be the best choice when you want to achieve sustainability. Of course, you also need to consider the price and long-term economic benefits, combining all aspects to help you make the best choice.

Ductless vs. Ducted

Benefits of Ductless Heat Pumps

Ductless heat pumps are simpler and easier to install. You need to open a 3-inch hole in the wall to connect the outdoor unit to the indoor unit.

Split ductless heat pump units can achieve higher SEER ratings, up to 25 SEER, resulting in significant cost savings.

A modern ductless air source heat pump consumes only 1 calorie of heat energy but can provide 1.5 to 3 calories. The unit does not produce heat. It only carries heat.

Ductless heat pumps provide consistent indoor temperature control saving you energy and money.

A ductless heat pump keeps less dust in your home because there is no airflow. Filters are added to each air-handling component.

A ductless heat pump, as the name implies, has no ducts, so there is no energy loss through the ducts.

Benefits of Ducted Heat Pumps

Ducted heat pumps' installation is faster.

Ducted heat pump systems take less time and money to maintain. We only need to maintain the outdoor unit and an indoor air handler.

If your house already has ducts, you can install a new heat pump and connect it to the existing ducts.

Ducted heat pump systems allow for more effective humidity control.

Ducted heat pump systems provide more fresh air to your house so you can avoid stagnant air.

With a ducted heat pump system, cool or hot air is passed through the vents, with no need for the indoor units, thus taking up less room space.

Advantages and disadvantages of air-to-air heat pumps

There are no perfect things in the world. Neither are air-to-air heat pumps. I will cover the advantages and disadvantages of air-to-air heat pumps to give you a comprehensive and objective understanding of air-to-air heat pumps.

Advantages of air-to-air heat pumps

Air-to-air heat pumps can perform heating and cooling functions, providing heating in the cold season and cooling in the hot season.
Air-to-air heat pumps do not require the installation of complex heat distribution systems such as radiators or underfloor heating.
The installation cost of air-to-air heat pumps is low and does not require using complex and expensive equipment.
Air-to-air heat pumps have a strong heat transfer capacity. And air-to-air heat pumps are highly efficient, with a seasonal efficiency rating (SCOP) of 3.0-4.0， meaning for every 1 kW of electricity consumed， they can produce 3-4 kW of heat.
The noise level of air-to-air heat pumps is not too loud, generally kept within 60 DB, with the latest air-to-air heat pumps much quieter.
Air-to-air heat pumps are green and do not release harmful substances into the atmosphere.
For any air-to-air heat pump, retrofitting is possible and feasible.

Disadvantages of air-to-air heat pumps

Although there are so many benefits, air-to-air heat pumps also come with some disadvantages of their own.

The COP of air-to-air heat pumps is greatly affected by the outside air temperature. Normally, the lower the temperature, the lower the COP.
At ambient temperature levels as low as -10 degrees Celsius and below, the motor's power consumption increases to ensure proper operation of the heat pump.
Air-to-air heat pumps naturally move the dust in the air as they move the heat in the air.

Is It Worth Installing Air to Air Heat Pump?

——

Air-to-air heat pumps are usually more expensive to install, but you save more money with low maintenance costs throughout the years, making air-to-air heat pumps a great investment. Air-to-air heat pumps are much safer, with no gas leak risks, which can expose you to carbon monoxide. Is it worth installing air-to-air heat pumps?
