Radiators



The Importance of Radiators in Heating Systems

Radiator heaters are efficient and cost-effective, converting much of the energy they consume into heat for your home. They also take less time than forced-air systems to warm up and are easy to maintain.

They work through thermal convection based on the principle that hot air rises and cold air sinks. They are made of metal, which is a good conductor of heat. Visit Radiator Traditional to learn more.

Heating

Radiator heaters are one of the oldest forms of heating systems but still very popular today because they’re relatively inexpensive to run and efficient. They use hot water or steam to heat the air through a combination of radiation and convection.

They work by relying on hot water or steam to warm up a series of coils or fins that then radiate thermal energy into the surrounding air. The warmth is typically regulated by a thermostat.

Hot water radiators have a boiler that creates steam or hot water, which is then pumped throughout your house via a network of pipes. The hot water or steam enters each radiator and is heated up by its coils or fins. The heat is then transferred to the surrounding air through convection, warming your home.

Radiator heating can also be zoned, using automatic valves to heat and cool different areas of your home on a schedule you choose. However, this system will require regular balancing to ensure that all of the radiators are giving off a similar level of heat.

Cooling

Radiators allow warm air to circulate without the need for a blower. This means that your home takes a bit longer to reach your desired temperature, but it also allows heat to be dispersed more evenly.

Radiator heating is more humid than forced air systems, as it uses water rather than a flame. Nevertheless, it can still dry out the air, requiring you to use a humidifier.

Hot water and steam radiators are connected to a boiler through pipes, which continually run hot water or steam into your home. The water becomes hottest when it passes through the radiator closest to your boiler, and cools down as it travels further away. This process is regulated by your thermostat, and is known as balancing. A thermometer can be placed on the inlet pipe to check the water temperature. Panel radiators feature welded panels with fins that increase surface area to improve convection. They can be either round or column style, and are referred to by their type number.

Ventilation

Radiator systems use a central boiler or water heater to produce steam or hot water that circulates through pipes to the baseboard heaters or standalone radiator units in your home. These pipes have fins and coils to increase their surface area and allow for greater convection.

As the heated water or steam passes through a radiator, it warms up and radiates heat into the surrounding air. This process can be accelerated with an electric or gas fan attached to the radiator, making it faster and more effective than forced-air heating systems.

Once your thermostat detects that the room has reached your desired temperature, it turns off the radiator circulator or shuts off the steam valve. This allows the hot water or steam to return to the water tank to be reheated. The same process can be used with ventilation radiators, except that incoming air is pre-heated to room temperature before it enters your home through vents in the wall or the radiator panels themselves.

Maintenance

Radiator heating systems rely on a centralized boiler or water heater to create steam or hot water that travels through a network of pipes. Once the hot water reaches the radiator, it heats up fins or coils and then radiates the heat to warm up your home and the air around you.

Radiators are usually made from a metal like steel, which is a good conductor of heat. The exterior of the radiator also has a set of fins that increase its surface area, which further heats up the surrounding air to speed up your home’s heat transfer.

Radiator heating systems sometimes require maintenance, especially if you have long pipe runs. Over time, these long pipes can develop pinholes that allow cold air to flow into the radiator. This can make your radiators go from warm to cold and back again, and will cause your system to draw more fuel to keep your house comfortable. To prevent this, your radiators may need to be bled every year.
