How to save on heating with electric radiators

Electric radiators are an excellent solution for heating indoor spaces, especially when you need a flexible and easy-to-install heating system. Their growing popularity is due to their ease of use and ability to heat specific areas independently, eliminating the need for a centralized heating system.

However, a common concern is the impact these devices may have on electricity bills. Fortunately, with a few precautions, you can maximize the energy efficiency of electric radiators, ensuring a warm and comfortable environment without skyrocketing energy costs. In this article, we provide a complete guide on how to choose and use electric radiators effectively, optimizing consumption and minimizing waste to help you save on your bills.

Choosing the Best Electric Radiator

Selecting the right radiator is one of the first steps to saving on heating. Not all radiators are the same—different models offer specific functionalities and performance to suit various needs.

Types of Electric Radiators

At Deltacalor, we offer a complete range of electric radiators designed to meet different space, performance, and design requirements while maintaining our high-quality standards. Here are the solutions we provide:

Dry Inertia Radiators
With a refractory stone heating element, these radiators store heat and release it slowly and evenly. They are the ideal choice for those who want consistent and long-lasting heating.

Fluid Inertia Radiators
Perfect for those who need to quickly increase the room temperature. This solution ensures fast and effective heat distribution without compromising comfort.

Gentle Heat Radiators
Featuring two heating cores—one in aluminum and one in refractory stone—our gentle heat radiators provide even, steady, and healthy warmth. They are recommended for those looking for a balance between rapid heating and continuous warmth. With these solutions, we are committed daily to combining quality, innovation, and design to offer maximum home comfort.

How to Choose the Right Model

The right radiator choice depends on several factors:

Room Size

The radiator’s power must be proportionate to the room’s volume. An undersized radiator may not provide adequate heating, while an oversized model may require excessive installed power.

Practical Tip: Use our Deltacalor Calculator to precisely estimate the required power (in watts) based on room size and the desired temperature, typically around 20°C.

Thermal Insulation Condition

The quality of your home’s or room’s insulation directly affects your radiator choice.

• Well-insulated rooms: If your space has modern window frames, double glazing, and well-insulated walls, you can opt for radiators with lower power.
• Rooms with thermal dispersion: In the presence of old windows, thin walls, or poor insulation, consider dry inertia or gentle heat radiators, which can compensate for heat loss with more consistent and long-lasting heat emission.
• Room Usage Function

The type of room where you install the radiator affects your choice:

• Bathrooms and kitchens: Choose radiators with rapid heating, such as fluid inertia models, which ensure an immediate temperature increase.
• Living rooms and bedrooms: Opt for dry inertia or gentle heat models, ideal for maintaining a constant and comfortable temperature throughout the day or night.

Optimal Installation and Placement

Once you’ve chosen the ideal radiator, proper installation and strategic placement can make a big difference in efficiency.

Where to Position Radiators

• Near exterior walls: Installing the radiator near exterior walls helps counteract heat loss typical of these areas.
• Away from obstacles: Avoid placing the radiator behind furniture, curtains, or other objects that block heat distribution. Always leave free space around the device.
• Low height: Positioning the radiator at floor level promotes even heat distribution, as warm air naturally rises.

Importance of Insulation

Good thermal insulation is essential to retain heat inside the room. Consider measures such as:

• Installing door and window seals to block drafts.
• Using thermal curtains.

Perform Regular Maintenance

Keeping your radiator clean and in good condition is just as important. Dust and dirt can reduce efficiency, so make sure to clean it periodically with a dry or slightly damp cloth.

Smart Use of Electric Radiators

Using electric radiators wisely is key to controlling costs. Even the most efficient device can lead to waste if misused.

Programmable Thermostat

Modern radiators come with programmable thermostats that allow you to:

• Set different temperatures for each hour of the day. For example, you can keep a lower room temperature at night or when you’re away from home.
• Create customized profiles for each room, adapting heating to your needs.

Advanced Features

Make the most of modern radiator features:

• Timer: Schedule automatic on/off times according to heating needs.
• Eco Mode: Automatically reduces energy consumption without sacrificing comfort.

Operating Modes

Choosing the right mode can optimize consumption:

• Anti-freeze: Maintains a minimum temperature to prevent freezing.
• Boost: Provides rapid heating for short periods.
• Comfort: Maintains an ideal temperature for well-being.

Additional Energy-Saving Tips

Optimizing radiator use means adopting habits that promote smart and sustainable consumption. Here are some practical strategies.

Avoid Heating Unused Rooms
Focus on the rooms you use daily. If a room is rarely used, significantly lower the temperature or turn off the radiator.

Lower the Temperature Slightly
Even a one-degree reduction can generate significant savings on your bill without compromising comfort. An ambient temperature of 19-20°C is optimal.

Adjust Radiator Operating Hours
Limiting radiator operating hours is a simple and effective way to reduce energy consumption and lower electricity costs. Using them only when necessary and turning them off when the house is empty can bring financial and environmental benefits.

According to ENEA (the Italian National Agency for New Technologies, Energy, and Sustainable Economic Development), it’s essential to consider your climate zone. Italy is divided into six climate zones, each with a maximum legal heating duration.
