What is better convector or radiator – comparative characteristics and tips on choice

Selecting the appropriate heating system is essential for maintaining a warm and comfortable home. Radiators and convectors are two common choices that are frequently brought up in conversations. While they both have the same function, which is to heat your space, they differ in a few key ways that could make one better suited for your house than the other. We’ll weigh the benefits and drawbacks of convectors and radiators in this post so you can choose the best heating solution for your needs.

Let’s talk about convectors first. In order for these heating devices to function, cool floor air must first pass over a heated element before rising back into the space as warm air. Convectors are renowned for their rapid heating times and uniform warmth distribution in a room. They’re frequently preferred for their ability to heat spaces quickly, which makes them perfect for spaces like living rooms or offices where frequent and quick heating is needed.

In contrast, radiators work by heating the water or oil inside of them, which then radiates heat into the surrounding space. Radiators typically distribute heat more slowly and gradually than convectors do. Even after the heating system has been turned off, they can, however, stay warm for extended periods of time once they’ve warmed up. This makes them especially appropriate for rooms like bathrooms or bedrooms where a constant temperature is desired.

Both convectors and radiators are available in a range of aesthetic styles and designs to accommodate various interior design tastes. Convectors fit in perfectly with contemporary design schemes since they are frequently smaller and sleeker. Conversely, homeowners can select a radiator style that matches the overall aesthetic of their home by selecting from a variety of traditional cast iron designs or more modern options.

The space you have in your house is a crucial consideration when deciding between convectors and radiators. Convectors are a sensible option for spaces with limited space for heating appliances because they usually take up less wall space than radiators. Convectors can also be positioned closer to drapes or furniture without preventing airflow, making the most of the available space.

The choice between convectors and radiators ultimately comes down to your personal tastes, the design of your house, and your unique heating requirements. You can make an educated decision that will keep your house warm and cozy for many years by comparing the benefits and drawbacks of each option.

Characteristic Tips on Choice
Heating Method Consider your heating needs and preferences. Convectors provide quick heating while radiators offer more consistent warmth.
Efficiency Look for energy-efficient models to save on utility bills. Both convectors and radiators can be efficient when properly sized and installed.
Space Requirements Assess the available space in your home. Convectors are often sleeker and more space-saving compared to radiators.
Heat Distribution Decide on the desired heat distribution. Convectors circulate heat quickly, while radiators emit warmth more gradually, providing a cozy atmosphere.
Installation Consider ease of installation. Convectors are typically easier to install than radiators, making them a suitable choice for DIY enthusiasts.

When it comes to heating your home, choosing between a convector and a radiator can be a tough decision. Convectors work by circulating air over a heated surface, while radiators heat up metal panels to warm the surrounding air. So, which one is better? Well, it depends on your specific needs and preferences. Radiators tend to provide a more consistent and gentle heat, making them great for larger spaces or rooms where you want to maintain a steady temperature. On the other hand, convectors heat up quickly and are ideal for smaller rooms or areas where you need rapid heat. Additionally, convectors are often more energy-efficient, but radiators can offer a cozy warmth that many prefer. Ultimately, the best choice for you will depend on factors like room size, heating ne

Water radiators: types, pros and cons

Radiators’ primary purpose is to provide heat for spaces. The efficiency of the appliances determines how comfortable the apartment or home will be during the heating season.

Produces an enormous variety of models with varying designs and materials.

Differences by design

According to their construction, radiators are separated into:

  • tubular;
  • sectional;
  • panel.

Steel, cast iron, and aluminum are used to make sectional models. For instance, cast-iron batteries have been manufactured since the USSR’s era.

The radiator is composed of sections, and the number of sections in the ready-to-install device is determined by the size of the room, its intended use (office, residential, or industrial), and the necessary heating intensity.

Sectional batteries are not the same as tubular batteries in terms of assembly quality or aesthetic appeal. The devices are made up of two coolant-filled compartments, one upper and one lower. Steel tubes connect the compartments to one another.

Although tubular models have a relatively high strength, they cannot withstand large pressure drops. As a result, their installation is restricted to single-family homes or structures with no more than five stories.

The coolant travels through vertical channels in the rectangular sections that make up panel radiators. Owing to their numerous design options, the devices can be integrated into any interior.

The reduction of panel radiators results in a minor working pressure. The installation of additional pumps is necessary for proper coolant circulation and effective radiator operation, which raises the cost of heating system installation. Panel models are therefore seldom utilized in private construction.

Material differences


Many homes constructed in the USSR still have cast iron radiators. They are still made today, but with a more contemporary style.

  • suitable for any heating medium;
  • do not require water purity;
  • constantly high heat output regardless of the period of installation;
  • Long-term heating after disconnection;
  • possibility to reduce or increase the number of sections;
  • application at the temperature of the coolant up to 130 ° C;
  • service life – at least 40 years.

Contemporary radiator made of cast iron

  • high weight (from 5 to 7 kg one section);
  • duration of heating;
  • small heat transfer area;
  • outdated design;
  • Difficulty in removing dust and dirt from surfaces.


Each section has 130–220 W of thermal power. Ordinary aluminum radiators have a working pressure of 6 atm, while reinforced versions have a working pressure of 12 atm.

  • heat dissipation;
  • low weight;
  • can withstand high working pressure;
  • suitable for installation in rooms of any design;
  • easy installation.

  • demanding to the acidity of the coolant – Ph not more than 7.5 units;
  • installation of an automatic air vent;
  • susceptibility to corrosion in contact with other metals.

Steel plate

Mostly installed in private homes. The coolant flows through internal channels in the plate sections that make up the radiator.

  • light weight;
  • high heat transfer rate
  • rapid heating;
  • ease of installation;
  • cost.

Radiator steel plate

  • Impossibility of installation in multi-storey buildings due to working pressure limitations;
  • poor resistance to corrosion;
  • need for constant filling with coolant.

Steel tubular

They are made up of two collectors joined by spot welding to steel pipes. To heat the space, a tiny amount of heat transfer medium is needed. able to be mounted both vertically and horizontally.

  • fast heating of the room volume;
  • choice of sizes and shapes.
  • susceptibility to corrosion;
  • cost.


Steel pipes are installed in aluminum panels to create this kind of radiator. Heat is carried by water; antifreeze, which ruins the device’s internal surfaces, is not permitted. Steel pipes transfer heat to aluminum panels, which in turn heat the air.

  • use at working pressure up to 30 atm;
  • no restrictions on the pH parameter;
  • high heat output;
  • use for heating large areas;
  • modern design.
  • installation of an automatic air vent;
  • complexity of installation;
  • cost.

Oil radiators

Water heaters and oil heaters work on a similar principle. The coolant used now is mineral oil rather than water, which makes a difference.

The oil is heated by a heating element inside, which then distributes heat to the surrounding air masses. not typically utilized as the primary heating source. Anywhere is a good place to install the heater: beneath the table, in the recreation area, close to the walls.

  • fast heating of a large area;
  • silent operation;
  • built-in thermostat;
  • possibility of relocation;
  • no installation required.

  • strong heating of the casing
  • constant control of the device;
  • high cost.


Types, design features

Convectors are appliances that use forced or natural hot air circulation to heat rooms.

  • rectangular metal housing;
  • heating element built into the lower part of the casing;
  • thermostat.

The device’s heating element draws cold air into the bottom openings of the housing, heats it up, and allows it to exit through the upper openings. The room’s volume is heated uniformly because of the air masses’ directed movement.

  • water;
  • electric;
  • gas.

Devices operate automatically, are safe, and require no maintenance.


When it is not possible to connect the house to the main gas network, electric models are installed. All that is needed for the device to function is a power source; batteries, a boiler, room plumbing, and a coolant supply do not need to be installed.

The concept of heat exchange underpins how electric devices work. As they rise and exit the convector, they warm the air masses in the space. The device draws in cold air from underneath the ceiling and moves it in the same direction.

Thermostats, whether mechanical or electronic, regulate temperature by turning on and off the heating element.

Choosing where to put the electric convector

  • autonomous operation;
  • absence of heat carrier;
  • the possibility of creating a group of convectors heating network, a kind of centralized heating of the whole house;
  • simplicity of design;
  • speed of installation;
  • environmental friendliness – the devices do not change the air humidity and do not burn oxygen.
  • drop in efficiency during continuous operation;
  • high consumption of electrical energy;
  • electric shock is possible when a defective appliance is in operation.

Even with their current drawbacks, electric devices are thought to be the most straightforward and inexpensive.


Moreover, convectors use a liquid heat carrier that has been heated by a boiler. The straightforward design of water devices ensures trouble-free operation and rapid room heating.

The devices feature a high-capacity heat exchanger made of steel or non-ferrous metals like copper and aluminum. The first ones’ high cost is offset by their longevity and resistance to corrosion. Aluminum plates allow air heating to occur while a heat carrier travels through copper pipes.

Water heating convectors are made in the following versions:

  1. Wall-mounted. They are placed under the window sill.
  2. Floor standing. Located at large windows or window openings with a low sill.
  3. Built-in. They are used to create a hidden heating system. Convectors are placed in prearranged wall recesses.
  4. In-floor. Prevent condensation on panoramic windows.

The floor water convector is integrated.

  • no energy consumption;
  • economical efficiency;
  • simplicity and compactness;
  • efficiency.
  • low efficiency when installed in rooms with high ceilings;
  • complexity of installation – the need for piping throughout the house;
  • low resistance to corrosion;
  • sensitivity to temperature fluctuations.

Water convectors are less expensive and simpler to use than electric convectors; all you have to do is use the boiler thermo regulator to set the desired temperature.


A recuperative heat exchanger serves as the foundation for the operation of gas convectors. Gas combustion products that exit the house through the chimney heat the air. Fuel options include liquefied propane-butane mixture and natural gas.

Regarding the installation process:

  • Floor standing. Used for heating large areas. Installed on a special concrete base.
  • Wall-mounted. Small size, suitable for any interior. Mounted under the window opening to compensate for the cold air. Installed in buildings with an area of up to 100 m2.
  • Built-in. Concealed installed in walls or floors.

Regarding the convection principle:

  • forced;
  • natural.

While the second type’s air masses travel from the bottom to the top and then move toward the ceiling as they heat up, the first type blows hot air. Cold air takes their place.

The gas fireplace in the living room

  • self-installation;
  • low gas consumption;
  • quick heating of rooms;
  • autonomy;
  • the possibility of using bottled gas;
  • cost.
  • obtaining permits for connection to the gas mains;
  • large amount of construction and installation work (holes in the walls, foundation for the boiler)
  • dimensions.

There are a few important things to think about when choosing between a convector and a radiator for home heating. It’s critical to carefully consider the benefits and drawbacks of each option before choosing one because they each have unique characteristics.

Convector heaters are renowned for their rapid and even heating of spaces. They function by pulling in cool air, warming it, and then redistributing it throughout the space. This quick heat-up time can be especially helpful in areas like living rooms and offices where frequent heating adjustments are necessary. Convectors are a common option for modern homes since they are also frequently more visually pleasant and smaller than conventional radiators.

However, for good reason, radiators have been a mainstay of residential heating systems for many years. They produce heat in a constant and reliable manner, making the entire space feel comfortable. Another benefit of radiators is that they hold heat longer—even after the central heating system has been switched off. Over time, this may lead to increased energy efficiency and financial savings.

Your individual heating requirements and preferences should be taken into account when choosing between a convector and a radiator. Aesthetic considerations, budget, room size, and heating requirements are all important factors to take into account when making a decision. Speaking with an expert in heating systems can also yield insightful advice specific to your situation.

Convectors and radiators, in summary, each have special advantages and disadvantages. The ideal choice for your house will ultimately depend on a number of variables. Your home can be kept warm and comfortable for many years to come if you make an informed choice by carefully assessing your needs and taking into account the features of each heating system.
