Heat pump
When you install a heat pump system in your home or business, you're opting for environmentally-friendly heating andhot water production, as well as greater efficiency.

Nature, your energy partner
Installing a heat pump not only allows you to produce heating and hot water in an environmentally-friendly way, it also offers greater efficiency than more traditional systems.
While some heat pumps draw their energy fromwater, others draw it from theair or ground. Whatever the energy used, the system relies primarily on renewable, sustainable energy. With this system, you produce your own source of energy !
Heating, hot water and, in some cases, cooling your home has never been easier!
benefits at a glance
Minimize your environmental impact
A heat pump is an environmentally-friendly heating system that uses a natural, renewable energy source. As a result, it consumes little energy, which means you minimize your environmental impact by reducing greenhouse gas emissions.
Enhance the value of your property
The installation of a heat pump can be an asset in increasing the value of your home on the real estate market, making it more attractive. Indeed, more and more potential buyers are sensitive to environmental and energy criteria when buying a property.
Save energy and money
With a heat pump system, you can achieve energy savings of up to 75% compared with conventional heating. This is due to its excellent efficiency: for every 1 kWh of energy generated, the system produces 3 kWh of heating. The system also pays for itself very quickly, despite the initial investment. You may also be eligible for cantonal and sometimes even municipal subsidies. Last but not least, these investments are 100% tax-deductible, which helps reduce the cost.

Heat pumps and solar panels - the perfect combination
Would you like to increase your energy autonomy and improve the profitability of your system? Then combine your heat pump with your photovoltaic system, so that it runs when your solar system is producing electricity! You'll increase your self-consumption of electricity thanks to locally-produced solar energy, and reduce your annual bill.

How a heat pump works
A heat pump owes all its performance to the way it works. The device is designed to draw heat from the environment outside your home. Once captured, the heat is transferred to your home's various heating systems. To heat the air inside your home, the heat pump will power the heating system. To produce domestic hot water, the captured energy is used to power the water heater.
Whether you're renovating or building a new home, SEIC's specialists will be happy to help you with your project.
Four stages define the operation of a heat pump
-
1. The evaporator
The heat captured externally is transferred to a refrigerant circulating inside the heat pump. Under heat, this fluid, which has a low boiling point, transforms into a gas.
-
2. The compressor
From the evaporator, the refrigerant is compressed in the compressor. During compression, the pressure and temperature of the fluid increase considerably.
-
3. The exchanger
The high-pressure, high-temperature refrigerant is then directed to a heat exchanger, through which the water in the heating circuit circulates. By becoming liquid, it transfers its heat to the water or air that will be used to heat the home or produce domestic hot water.
-
4. The regulator
As the liquid passes through the expansion valve, its pressure drops. This drop in pressure is accompanied by a significant drop in temperature, and the refrigerant returns to its liquid state. The cycle can begin again.
