How Do Central Heating Radiators Work?

Central Heating Radiators are very important when it comes to weighing down the workings of a central heating system’s components. Although the boiler and thermostat contribute largely toward controlling the amount of heat you want to produce in your home, the radiator in every room can be used to control individual room heat. The concept behind the radiator is very simple and easy to understand. Knowing how central hating radiators work and how they can be combined with thermostatic radiator valves can help you easily regulate the heat around your house.

Central Heating Radiator

The radiator works on a simple scientific method. It is composed of a copper pipe that is bent at right angles several times. Usually, 15-20 bends can be seen in a common central heating radiator. The bends increase the surface area through which heat will travel in the radiator.

At the bottom of a central heating radiator is a small valve that can be turned up or down. On turning fully down, the hot water flowing through the copper pipes can be stopped, turning the radiator ‘off’. When the valve is turned up, the radiator turns on as hot water starts flowing. Depending on how much heat you want to produce in a specific room, you can control the amount of time the radiator stays on. Even when the radiator is switched off, the hot water that has accumulated in the copper pipes produces a fair amount of heat.

Thermostatic Radiator Valve

A thermostatic radiator valve, combined with a radiator, can give you increased control over the amount of heat you want in a specific room. Earlier, you read how you can turn the radiator only on or off to control heat. When combined with a thermostatic valve, you can do more! The process of heating initially involves a central heating boiler firing up. The radiator is then filled with hot water and heats up rapidly to its highest temperature. If you have connected the radiator to a thermostatic valve, the rapid heating up of the radiator can be controlled, depending on the setting you have previously set on the thermostatic valve. This means that you don’t have to necessarily wait for the radiator to reach full heat, then turn it off to control heat, then turn it on, and so on. The radiator does that automatically when connected with a thermostatic radiator valve. These mini mods to your central heating system can be done by hiring companies like TS Heating for example.
