RESIDENTIAL SOLUTIONS
Total Energy Solutions helps individuals and businesses reduce their energy costs through modern heating, cooling, and clean energy systems. From design to installation, we focus on comfort, efficiency, and reliability.
RESIDENTIAL PHOTOVOLTAIC SYSTEMS – NET BILLING
Total Energy Solutions manages the entire process to help you install a photovoltaic system with net billing, in accordance with the current regulatory framework.
From the initial study to installation, we design the system to meet the real needs of your home and maximize self-consumption and your financial benefit.
What is net billing in simple terms?
Net billing (real-time energy offsetting) is the new self-generation model.
With this system, energy production and energy consumption are treated as two separate financial activities.
The electricity you produce and consume at the same time immediately reduces your electricity bill.
Any excess energy that is not consumed is fed into the grid and sold at wholesale prices, providing you with financial compensation.
The electricity you need when there is no production is purchased normally from your provider at retail prices.
How does it work in practice?
✔ The smart meter operated by DEDDIE records production and consumption separately.
✔ Energy consumed immediately reduces the electricity bill.
✔ Surplus energy is fed into the grid and financially compensated.
✔ When additional electricity is required, it is supplied by the provider at retail prices.
The higher the level of self-consumption, the greater the financial benefit.
The system is designed to ensure optimal use of the generated energy, taking into account both current and future household consumption, providing stable performance and long-term cost control.
NATURAL GAS
Contact us for an on-site inspection of your property and proper guidance for installing natural gas in your apartment. The most common solution is the installation of an individual boiler, which provides both space heating and domestic hot water.
The boiler is connected to the existing radiators and controlled via a room thermostat. Modern condensing boilers offer higher efficiency by utilizing heat from exhaust gases and significantly reducing operating costs.
Compared to oil heating, savings can reach 40–50%, making the transition to natural gas a cost-effective solution with fast payback.
✔ Heating and domestic hot water with a single system.
✔Up to 40–50% lower cost compared to oil.
✔High efficiency with condensing boilers.
✔Temperature control via a room thermostat.
✔Certified equipment with warranty.

RESIDENTIAL ENERGY RENOVATION
We upgrade your property’s energy performance by reducing operating costs and improving your home’s energy rating.
Through targeted interventions, your home becomes more efficient, more comfortable, and more economical to operate, while adapting to modern energy and mobility needs.
Energy renovation is not only about reducing electricity or heating bills, but also about improving overall quality of living, achieving energy independence, and increasing property value by integrating modern infrastructure such as electric vehicle charging.
✔ Improvement of the home’s energy rating.
✔ Reduction of heating and cooling costs.
✔ Thermal insulation of the building envelope (walls).
✔ Thermal insulation of the roof, terrace, or pilotis.
✔ Upgrade of domestic hot water systems.
✔ Installation of electric vehicle chargers.
✔ Combination of interventions for maximum energy savings.
HEAT PUMPS
Heat pumps are the modern solution for residential heating and cooling,
combining high energy efficiency with low operating costs.
They harness energy from the environment and convert each kilowatt-hour of electrical
energy into multiple units of thermal output, providing comfort all year round.
In the Greek climate, where winters are mild, heat pumps operate with even greater efficiency. Savings on heating costs are immediately noticeable, while the investment is recovered within a short period, without compromising the thermal comfort of the home.
✔Up to 60–70% lower heating costs.
✔Stable performance even at low outdoor temperatures.
✔Ideal for fan coils and underfloor heating systems.
✔Payback period of 1–2 years.
✔Can be combined with photovoltaic systems and off-peak electricity tariffs.

SOLAR WATER HEATERS &
SOLAR THERMAL SYSTEMS
Total Energy Solutions offers solar water heaters and solar thermal systems that provide hot water for domestic use and heating. By harnessing solar energy, they help reduce costs and contribute to limiting the use of other forms of energy that have high production costs (such as electricity).
Installing a solar water heater significantly reduces domestic hot water expenses. The annual savings on hot water costs can reach up to 50% compared to other energy sources (oil, electricity, biomass, etc.).
A solar water heater harnesses heat from the sun’s rays and uses it to heat water. Solar water heaters are available in closed-loop and open-loop systems.
They consist of two main components:
✔Solar energy collectors.
✔The hot water storage tank (boiler) – dual-energy boiler.
Depending on the storage tank, they are classified as:
Dual-energy boiler (in addition to the solar collectors, hot water can also be produced using the integrated electric heating element, which is typically used on cloudy days).
Triple-energy boiler (operates like the dual-energy system, but also includes an inlet connection to the central heating system, allowing hot water production from an existing boiler or heat pump).
