To make the best choice, the first thing you need to do is to estimate your needs. Remember that the air-to-water heat pump is an investment and that its profitability is not calculated in the short term. You must take into account the future energy savings you will make with this device. The criteria to take into consideration during this study phase are
- The type and shape of your home
- The volumes to be heated
- The type of current heating system
- The space available for the air-to-water heat pump
- Heating habits
- Access to city gas in your neighborhood
Depending on the conclusions you draw, an RGE professional will be able to confirm whether your home is compatible with an air-to-water heat pump or not.
The coefficient of performance defines the performance of an air-to-water heat pump in heating mode. In other words, the COP establishes the ratio between the electrical power consumed by the compressor and the heat power replaced by the device. For the case of an air water heat pump, the COP is between 3.4 and 5. Logically, the higher this coefficient is, the more efficient this ecological heating is. A machine with a COP of 3.5 kW will deliver 3.5 kW of heat for 1 kW of energy consumed. Note that this coefficient will influence the allocation of the premium for the work to be done.
The seasonal coefficient of performance defines the performance of the air-water heat pump during the entire period of operation. To do this, it takes into account three European climates, that of Athens, Strasbourg and Helsinki. Thus, air-to-water heat pumps are classified from A+++ to A, i.e., from the best to the worst in performance.
The thermal power refers to the amount of heat produced by the heating device. For air-to-water heat pumps, the heat output must be between 5 and 20 kW. For a device to properly heat your home, three data must be taken into account. It is about :
- The volume of the house
- The construction coefficient: from 0.6 for a well insulated house to 1.6 for a poorly insulated house.
- The difference between the desired temperature and the temperature of your region.
To obtain the thermal power you need, you must make the ratio between these three data (volume of the dwelling x construction coefficient x temperature difference).
This technology has the mission to regulate the production of heat coming from the device. Basically, it smoothes out the heat production over time. This technology is essential in that it optimizes energy consumption while providing even and gentler heating.
To reduce the cost of purchasing and installing an air-to-water heat pump, the government offers various types of assistance, the most popular of which are the following
The CEE Energy Allowances or 2021 Energy Allowances
Implemented in January 10, 2019 and renewed until December 2021, this "heating boost" premium allows the lowest incomes to benefit from a premium of 700 to 4000 €, and from 450 to 2500 € for medium and high incomes.
Aid from the ANAH
The National Housing Agency also provides funding to all households wishing to carry out energy saving work. If the modest incomes are entitled to a premium with a ceiling of 7000 €, the very modest incomes are entitled to up to 10000 €. Note that the ANAH aid can be combined with the heating incentive.
The zero-interest eco-loan
If you have no savings to pay for the purchase of equipment and the labor of professionals, you can obtain from a bank a sum of zero interest. But to benefit from this aid, you must meet the eligibility requirements.
The reduced rate of VAT
Usually, a VAT of 20% applies to all consumer products. However, in the case of work aimed at reducing energy consumption, you are entitled to a reduced VAT rate. For a project to install an air-to-water heat pump, this rate is 5.5% if you are the owner of a home completed more than 2 years ago and if you entrust the completion of your project to an RGE-labeled contractor.
Installing an air-to-water heat pump is a project that cannot be improvised. The same applies to the choice of equipment. For a project of this nature, you can't do without the assistance of an RGE-labeled professional. It is also one of the conditions sine qua non for obtaining the bonuses granted by the government.
An air-to-water heat pump is said to be a monobloc when it takes the form ofa single compact unit. In other words, the hydraulic module and the compressor are one unit. Of course, it is connected to the heating circuit by a hydraulic connection. This model is not only more ergonomic, but it is also less expensive and easier to install.
A heat pump is called bi-block when its compressor is installed outside the home, while the hydraulic module is placed inside. These two units are joined by a refrigerant link. It is true that the monoblock model is more efficient, but it is also more expensive and more complex to install.
In the case of a low-temperature air-to-water heat pump, the water outlet temperature is between 35 °C and 45 °C. The difference between the outside temperature and the temperature of the water in the heating circuit is small. Nevertheless, the efficiency of the device is higher and it requires heat emitters or hot water radiators for example.
With the high-temperature air-to-water heat pump, the water outlet temperature is around 65 °C. This makes it easier to maintain conventional high-temperature heat emitters. Unlike the low-temperature air-to-water heat pump, this device does not require any special equipment.
The choice of an air-to-water heat pump depends on the nature of the work you are planning to do. For a new construction, specialists recommend installing a low-temperature air-to-water heat pump, which provides better efficiency. In the case of a renovation, a high-temperature air-to-water heat pump is better suited.
Among all the solutions for heating, cooling and supplying domestic hot water to a house, the air-water heat pump offers many other advantages.
If your home is already equipped with a boiler connected to hot water radiators or underfloor heating, you do not need to modify the entire equipment. Some air-to-water heat pumps are compatible with existing equipment. To put it simply, it simply replaces the old boiler that runs on fossil fuels or electricity.
Taking into account its operation, the air-water heat pump is financially advantageous compared to other heating methods. This device draws calories from the air, which is a free and renewable resource. People who adopt this device spend three times less money for heating and domestic water.
Although the installation of an aerothermal pump is expensive, the project pays for itself very quickly because of its exceptional performance and the energy savings it provides. In addition, its heat creation process, based on calories present in the air, makes it a very clean heating device. It is not futile to add that the heat pump is a high quality device with a lifespan of 15 to 20 years.
You can lighten your initial bill thanks to the numerous aids that are granted by the State. France is not the only country that encourages the installation of an air-source heat pump. Many European countries also offer subsidies to all their citizens who plan to heat with green energy.
The monobloc heat pump takes up very little space compared to a gas or oil boiler. Since it is also discreet, the device will not attract attention.
In our opinion, the best brands of air water heat pumps in 2022 are :
In just over 40 years of existence, Atlantic has never disappointed its public. Its range of air-to-water heat pumps is designed to meet the needs of people considering a home renovation.
Saunier Duval specializes mainly in hybrid heat pumps. Nevertheless, its range of air-to-water heat pumps remains very efficient.
A true pillar of the automotive industry, Mitsubishi Electric is also known in the world of household appliances. Highly efficient, this brand's air-to-water pumps are able to operate even when the temperature is at its lowest.
With more than 4 million units sold in 2019, Hitachi is establishing itself as the world's 2nd largest heat pump manufacturer. Its recent partnership with home automation specialist Somfy further strengthens this hard-won position.
Created in the 1920s, Daikin is now a reference in terms of heat pumps. Daikin products come at a higher price, but that's hardly surprising given their quality.
The diagram below will help you to get an idea of the typical prices for each price range (entry-level, mid-range and high-end).
However, more expensive does not necessarily mean better.
We therefore advise you to always consult our ranking before deciding, rather than blindly relying on price ranges.
Opt for a reversible unit
A reversible air-to-water heat pump can be transformed into an air conditioner. This reversibility will be very useful for cooling your home in summer.
Place the outdoor unit far enough from the house
The air-to-water heat pump is a system that can be noisy. To avoid the noise from the outdoor unit, have it installed far enough away from your house, if possible of course.
Use anti-acoustic solutions
If the previous tip proves ineffective, you can always cover your installation with a soundproofing screen or anti-vibration pads. That way, your neighbors won't be disturbed either.
If you lack space, opt for the monobloc
Depending on the model, heat pumps require space. If you don't have enough outdoor space, consider a packaged air-to-water heat pump.
Have your installation maintained
To ensure proper operation and longevity, have your system maintained by a qualified professional. If the terms of the annual maintenance contract seem advantageous to you, do not hesitate to sign.
In summer, reversible heat pumps will allow you to maximize your energy savings. To properly heat a 100m² home that respects RT2012 standards, the recommended power is 4200 watts or 4.2 KW.
No, this maintenance is not mandatory, but it is highly recommended. This maintenance must be done by a professional. Even if you are a good handyman, avoid touching the circuitry of the appliance, as this could damage it.
The government has put in place a significant number of schemes to minimize your personal input to complete this type of project. However, make sure you meet the criteria before applying for assistance.
