Key Points to Remember about solar heater for house

• Active solar heating uses sensors to transfer heat from the sun into your home.
• Passive solar heating, on the other hand, relies on the design of your building to naturally capture and distribute heat.
• Solar systems can also be used for air conditioning, using the sun’s energy to cool your interior.
• Solar thermal heating is great for hot water and can even help heat your home via underfloor heating.
• For a home solar radiator, recent models are often programmable and connected, which helps to better manage energy and save money.

1. Active solar heating

Active solar heating, unlike passive heating, uses mechanical components to capture and distribute heat from the sun. It’s a bit like having a heating system that actively works for you.

It should be noted that active solar heating uses solar thermal collectors to capture heat from the sun and transfer it to the building’s heating system.

Here are some key elements to consider:

• Solar thermal collectors: They absorb solar energy and convert it into heat.
• Heat transfer fluid: This fluid circulates in the collectors, recovering heat.
• Heat exchanger: It transfers heat from the heat transfer fluid to another fluid or air, which is then distributed throughout the building.

Active solar heating can be used to heat domestic hot water, air, or both. It requires professional design and installation to ensure optimal efficiency. It is important to properly size your domestic heating system to avoid energy waste.

Basically, active solar heating is a bit more technical than passive, but it can be super efficient if done well. You can even combine it with other systems for optimal heating. For example, you can use an aerothermal heat pump as a supplement for days when the sun isn’t out. It’s a solution that can really help reduce your energy bill and carbon footprint. Unfortunately, it seems there’s a database issue preventing access to some additional information, but the essentials are there.

2. Passive solar heating

Passive solar heating is an ingenious approach to heating your home using the sun, but without complex mechanical systems. The idea is to design the building itself to capture, store, and distribute solar heat naturally. It’s a bit like turning your home into a giant solar collector.

The fundamental principle is to optimise the orientation, insulation, and building materials to maximise solar gains in winter and minimise overheating in summer.

Here are some key elements of passive solar heating:

• Orientation: Large glazed surfaces are generally south-facing to capture maximum sun in winter.
• Insulation: Good insulation is crucial for retaining captured heat and reducing heat loss.
• Thermal mass: Materials with high thermal mass, such as concrete or stone, store heat during the day and release it slowly at night.

Passive solar heating is particularly effective in sunny regions, but it can also be used in colder climates with appropriate design. It is important to note that passive solar heating generally does not provide 100% of a home’s heating needs, but it can significantly reduce energy consumption and heating costs. A well-designed passive house can meet 50-60% of its heating needs through passive solar gains.

Speaking of savings, did you know that by optimising architecture to exploit solar radiation, you can reduce lighting needs and improve the energy efficiency of buildings? This is called passive solar energy.

3. Solar heating and cooling systems

Solar energy represents a renewable and abundant resource. Harnessing this energy allows buildings to be heated and cooled without relying on fossil fuels. Solar systems can be active, using sensors and pumps to transfer heat, or passive, relying on the building’s design and materials for natural heat circulation. Solar air conditioning systems use solar energy to power absorption chillers or desiccant cooling systems, offering efficient and environmentally friendly air conditioning.

There are several types of systems, each with its advantages and disadvantages. The choice will depend on your specific needs, your budget, and the configuration of your home.

It is important to carefully assess your needs and call on a qualified professional to advise you on the most suitable system for your situation. Correct installation is essential to guarantee the efficiency and durability of your solar system.

Here are some things to consider:

• The climate of your region
• The size of your home
• Your budget
• Your heating and cooling needs

The integration of these systems helps to reduce the carbon footprint of buildings. In renovation, it is possible to opt for hybrid solutions, combining, for example, a heat pump with solar thermal collectors. These solutions make it possible to optimise energy performance and reduce operating costs. It is important to note that solar thermal heating is particularly effective in passive or bioclimatic houses, requiring good storage to compensate for intermittency.

In new construction, the Environmental Regulation 2020 (RE2020) imposes strict criteria for CO₂ emissions and energy consumption. Solar heating and cooling systems can help achieve these objectives. For example, a solar water heater or a combined solar system can cover part of the hot water needs. In addition, the use of an aerothermal heat pump can be an effective solution for heating and cooling, reducing dependence on fossil fuels. It is also possible to opt for a residential air conditioning system to maintain optimal thermal comfort at home.

4. Solar thermal heating

Solar thermal heating uses the sun’s energy to produce heat, which can be used to heat water or air in a home. It is an ecological and economical solution to reduce your dependence on fossil fuels. It is important to note that the efficiency of the system depends on the sunshine in your region and the size of your installation.

There are mainly two types of solar thermal heating systems:

• Active systems, which use pumps and fans to circulate heat.
• Passive systems, which use the building’s design to capture and distribute heat.

Solar thermal heating is an excellent option for reducing your carbon footprint and energy bills. However, it is important to properly size your installation and choose a system adapted to your needs.

Here are some elements to consider when choosing a solar thermal heating system:

8. Radiant heater

The radiant heater, also called a radiant panel or radiant radiator, represents an improvement in energy efficiency compared to traditional convectors. Instead of heating the ambient air, it uses a radiant plate to emit heat in the form of infrared radiation. This heat is directly absorbed by people and objects in the room, providing a faster and more pleasant sensation of warmth.

The main advantage of this type of radiator is its ability to quickly heat a room. However, it is important to note that the heat disappears as soon as the radiator is turned off, as it does not accumulate heat like inertia radiators.

Radiant heaters are particularly suitable for rooms where quick and localised heating is necessary, such as bathrooms or guest rooms. They are also more efficient in well-insulated spaces, as they do not rely on air circulation to diffuse heat.

Here are some advantages and disadvantages of radiant heaters:

• Very fast temperature rise.
• Good energy efficiency.
• Targeted and comfortable heat.
• Does not heat the ambient air, which can be a disadvantage in large rooms.
• Heat disappears quickly after the radiator is turned off.

In 2025, radiant heater models are becoming increasingly sophisticated, with programming and remote control options to optimise their use. For an efficient heating solution, the radiant heater can be an excellent choice.

9. Dry inertia radiator

The dry inertia radiator is a heating solution that has gained popularity thanks to its ability to offer gentle and constant heat. Unlike conventional convectors, it accumulates heat in a solid material, then gradually diffuses it into the room. This type of radiator is often perceived as a more economical and comfortable option.

The principle is simple: an electric resistance heats a solid heating core, which can be made of cast iron, ceramic, lava stone, or other refractory material. Once hot, this core continues to diffuse heat even after the resistance is turned off, which helps maintain a stable temperature for longer. It’s a bit like having an economical electric heater that works for you, even when it’s not actively consuming electricity.

Here are some advantages and disadvantages to consider:

• Gentle and even heat
• Good thermal inertia (heat retention)
• Potentially reduced consumption compared to convectors
• Slower temperature rise
• Generally higher price

Dry inertia offers more stable and pleasant heat, but you should be aware that the radiator will take longer to heat the room initially. This is a compromise to consider depending on your needs and budget.

There are also double-core radiator models, which combine a radiant panel and a dry inertia core. These models offer a rapid temperature rise while maintaining good inertia, but they are generally more expensive. If you are looking for a heating solution that reacts quickly while being comfortable, this is an option to explore.

In summary, the dry inertia radiator is a good choice for those seeking lasting thermal comfort and controlled energy consumption. It is particularly suitable for living rooms where a lot of time is spent, such as the living room or bedrooms. Don’t forget to compare the different models and materials to find the one that best suits your needs and budget. Also, consider the installation, a well-installed electric radiator is a radiator that lasts!

10. Connected radiator

Connected radiators represent a significant advance in domestic heating. They offer optimised temperature management and a potential reduction in energy consumption. More and more thermostats are connected, allowing heating to be adjusted via a smartphone, tablet or computer application, to benefit from true connected radiators.
