Although a small and minimal addition to any hydronic heating installation, radiator valves are a necessary component when it comes to all radiator purchases. These small dials marginally increase the efficiency of all heating systems by offering greater heating control thus creating an ideal solution towards money saving heating options.
The extensive range of radiator valve fitting types and styles can often be overwhelming which only makes choosing the right option for your boiler or radiator confusing and challenging without the appropriate knowledge of heating systems. With a large range of styles and finishes, it is important to install the correct radiator valve to your system in order to encourage the best efficiency possible of your radiator as well as complete control over your heating.
There are three main types of radiator valves, each are explained below to assist you in selecting the right valve for your unique radiator.
Manual radiator valves.
Although dependent on manual control, this style proves simple and easy both to use and to maintain.
Manual valves are the most common style among all radiator valves. These, being the most traditional example of valve, look and operate similar to a regular water tap. The valve functions in the same way, simply by turning the dial to control the release of hot water that enters into the radiator in order to generate the radiation of heat.
There are three shape types of this style of valve; corner, angled, or straight. The shape of the radiator valve you require will vary depending on the location of the valve inlets on each individual radiator. The valve will also depend on the type of system installation you have; whether the piping is installed in the walls or underneath the floor.
Lockshield valves function to manage the rate at which the radiators heat up all over the house or work area to make the heating operation most efficient. These valves rather control the volume of water that flows OUT of the radiator in order to ensure the most even distribution of heated water across the radiator and thus across the indoor space as possible.
Thermostatic radiator valves (TRV).
A TRV type valve functions similarly to a manual valve by completely the same action of controlling the release of water that enters into the radiator. However, a thermostatic valve is self-regulating by measuring the air temperature that surrounds the system and adjusting the heat output into the room accordingly. The TRV model also offers the option to heat individual rooms at varied temperatures, so that more frequently used spaces may be heated more regularly than rooms less used. When the radiator has produced the desire temperature, the valve closes automatically in order to not overheat the surrounding area.
The thermostatic valve operates in this manner as to reduce overall energy consumption.
