Save energy with the installation of a thermodynamic water heater.
Install a thermodynamic water heater and use solar energy to heat the water in the house.
The principle of the thermodynamic water heater
Thermodynamic water heaters work with a heat pump integrated into the hot water tank.
The principle of the heat pump is to capture the calories present in the outside air. This is the principle of thermodynamics.
The calories present in the outside air are transported to the interior of the house thanks to a closed and airtight refrigerating circuit.
The installation consists of a storage tank and a heat pump.
Simple and quick installation
The thermodynamic water heater does not require any major work, since it is sufficient to replace the electric water heater with the thermodynamic water heater and supply it with outside air via an air intake.
Since the energy contained in the air is free, you only consume the energy needed to operate the heat pump. The installation of a heat pump makes it possible to divide by 3 your energy consumption for heating your home.
The operation of a thermodynamic water heater
How does it work?
The heat pump is composed of a compressor, two exchangers: One to capture the energy outside (evaporator), the other to release it inside (condenser) and an expansion valve.
The compressor will suck in the refrigerant, which is in the form of gas at low temperature. By compressing the gas, its temperature will rise along with its pressure.
The hot gas will be directed to an exchanger (called a condenser) in which a fluid to be heated circulates.
The heat of the environment present in the air is free energy that is constantly renewed thanks to solar radiation and rainfall.
The heat pump takes this heat from the environment and transfers it to a higher temperature level in the homes to heat them.
It is during these operations that the very low consumption of electrical energy takes place.
Indeed, for 1 kwh of electrical energy consumed, 3 to 4 kwh of thermal energy are returned. The thermodynamic water heater thus makes it possible to cover 100% of the domestic hot water needs of a dwelling by consuming only 30% of electrical energy. The remaining 70% is drawn from the air while preserving the environment. The thermodynamic water heater is a high-performance solution to produce heat from free energy drawn from the environment.
The installation of a thermodynamic water heater in your home
Mise and oeuvre
The installation of a thermodynamic water heater does not require any major work, since it is sufficient to replace the electric water heater with the thermodynamic water heater and supply it with outside air via an air intake.
The installation must be done by a professional.
Remember to check that your installer has the qualipac label, an independent label that carries out regular checks on the installer’s site.
A thermodynamic water heater requires annual maintenance to optimize performance and increase its lifespan.
The annual check of the tightness of the refrigerant circuit is compulsory for installations with more than 2kg of refrigerant and must be carried out by a company holding the prefectoral approval or certificate of capacity.
Before installing your heat pump, check that your installer has this certificate so that he can carry out the maintenance of your heat pump.

The cop: Coefficient of performance is the reference unit of a heat pump.
What is the cop?
It is the power restored in relation to the power consumed.
That is to say, the quantity of kilowatt-hours produced for 1 kwh consumed.
The higher the cop, the more efficient the thermodynamic water heater is.
The storage capacity of the hot water tank.
It will be defined according to the number of people occupying the dwelling. A consumption of 50 liters of hot water per day per inhabitant is an average. It is therefore necessary to have enough hot water in storage to meet the daily needs of the inhabitants.
For a family of 4 people, a 300-liter tank is usually proposed.
How much does the installation of a thermodynamic water heater cost?
What is the cost?
The installation of a thermodynamic water heater is an important investment that will be amortized by the energy savings made.
For a turnkey installation of a thermodynamic water heater, it is necessary to plan between 4 000 and 5000 €.
This includes the storage tank with the heat pump, the various supplies as well as labour for installation and commissioning.
Tax credit for the installation of a thermodynamic water heater a reduced investment thanks to the tax credit.
The french state wishes to help the development of the use of renewable energies.
26% tax credit for thermodynamic water heaters
What amount of expenses does the tax credit apply to?
The tax credit covers the price of equipment and materials, excluding labour, meeting the characteristics.
What is the amount of expenses eligible for the tax credit?
For the same taxpayer and the same dwelling, the amount of expenses eligible for the tax credit may not exceed, for a period of five consecutive years between january 1, 2010 and december 31, 2015, the sum of € 8,000 for a single person, widow or divorced and € 16,000 for a couple subject to joint taxation. This sum is increased by €400 per dependant within the meaning of articles 196 to 196b.
To find out your rights to the tax credit, you are advised to refer to the provisions of article 200 quater of the general tax code.
For the application of this measure, it is strongly recommended to refer to :
The website www.impots.gouv.fr (page on the tax credit)
Article 200 quater of the general tax code, article 90 of the 2005 finance act, article 83 of the 2006 finance act, article 109 of the 2009 finance act and article 80 of the 2010 finance act.

Some regions, town halls or the anah also subsidize the installation of photovoltaic panels by granting financial aid. Find out more directly from these administrations or from your espace info energie.
Vat at 5.5% for the installation of a thermodynamic water heater vat reduced to 7% for livings over two years.
An investment quickly amortized thanks to the energy savings made:
You divide by 3 your energy consumption for domestic hot water in your home.
This can represent several hundred euros per year.
The installation of a thermodynamic water heater can save up to 75% of the energy needed to heat domestic hot water. This represents for a 4-person household equipped with 2 solar collectors and a 300l storage tank an annual saving of 2700kwh.
With the tax credit, the various financial aids and the energy savings made, the investment of a solar water heater installation is amortized in a few years.
The environmental impact of the installation of a thermodynamic water heater
By heating the domestic hot water in your home with a thermodynamic water heater, in addition to the significant savings, the amount of energy not consumed compared to a conventional water heater significantly protects our planet.
Even if the thermodynamic water heater requires electricity consumption, the environmental impact is divided by three due to the low power consumption of the heat pump.
3 times less electricity consumed, it is 3 times less electricity to produce and therefore 3 times less greenhouse gas emissions.
Using the calories present in the air means contributing to the protection of our environment.
Renewable energies are inexhaustible and contribute to the good health of our earth.
