Radiator fittings and accessories - the most popular solutions

Central heating is one of the most essential installations of every building. It’s proper functioning is crucial. Heater, also called radiator, is the primary element of every heating system. It is used in most of the rooms in every household - therefore one should install it properly and equip it with adequate accessories. A malfunctioning device might make a room very uncomfortable. Heater accessories can significantly increase lifespan of a radiator. Find the suggestions on how to choose the best equipment in the article below.

Heaters - types and models

There are many types of radiators on the market. Each model requires a different kind of equipment. There are heaters such as:

  • panel radiators,
  • aluminium radiators,
  • iron-cast heaters,
  • convectors,
  • forced-air vents,
  • infrared heaters.

Heaters can be also divided by the method or place of their installation or by how they are powered. Apart from radiator, one should also install certain devices, otherwise the heater would not work. Valves, bleeders, installation accessories, stands, hangers and other radiator fittings are basic elements for every heater.

Radiator valves - a basic heating equipment

There are three main types of radiator valves. They can be divided by scope and method of their functioning. They are:

  • thermostatic radiator valve - it adjusts the temperature automatically, thanks to which the temperature is the same in every room,
  • manual radiator regulator - a typical device that is used to modify the room temperature (there are two types - with single and dual method of regulation),
  • stop valves - they allow for opening and closing the water flow (they can be pneumatic or regulated by steam or hydraulic fluid).

Radiator valve - important features

Every central heating installation should contain a thermostatic valve placed on the radiator. Such devices are used for regulating and controlling temperature of heaters. A thermostatic radiator valve adjusts the heating in a room to match individual needs of a user.

Radiator valve construction

Every radiator valve consists of two basic units. They are poppet valve and mechanical thermostatic valve. The valve reacts to the temperature surrounding it, changing the position of the valve head. This way the stream of water flowing through the radiator is properly adjusted.

A radiator valve consists of three main elements:

  • The first, main part is the temperature sensor. The element is usually a small container with a medium (liquid, gas or solid) and a pin that gets longer or shorter, depending on the temperature.
  • Other elements, equally important for proper functioning of the valve are valve lifter and handwheel. They allow to change the power of a radiator and reach the desired temperature.

Thermostatic radiator valve for underfloor heating

Manufactures also offer thermostatic radiator valves with an external temperature sensor. It is connected with a lifter by means of a thin tube, called capillary tube.

A thermostatic valve of this type is usually installed if a heater is located in a hard-to-reach place. The product is perfect for floor and wall heaters, which are hidden behind wooden covers or curtains.

How do radiator valves work?

A radiator valve simply regulates water stream, which is sent from boiler to the ending point of a heating installation - radiator. Keep in mind that a radiator valve does not regulate water temperature - it’s done by the boiler controllers.

When the room gets cold, the liquid inside the valve affects the coil, which causes the valve to open the water stream. As a result, the device gets warmer. When temperature of the room is adequate, the valve cuts the water off, causing the heater to cool off. In consequence, the room gets colder.

Each valve should contain clear and easy to read symbols on its surface. The lowest temperature is usually marked with a snowflake, and the highest - with a sun. Such symbols make it easier to find the desired temperature level.

Bleeding valves

One of the most important heating accessories is a bleeding valve. This small device is usually installed on the side of a radiator.

Why is this so important? If there is too much air in a heater, the device cannot work properly. It might result in underheated household. A bleeding valve helps to remove excessive gases from the installation, reducing the risk of malfunction.

Installation accessories for heaters

Radiator fittings and accessories are not just equipment that improves a heater’s proper functioning. This group includes also elements that are used to install a radiator. What does one need to install a heater? The most common elements are:

  • hook,
  • handle,
  • hanger,
  • needle,
  • installation module.

Using products of this type for installation guarantees that the installed radiator is firm and stable.

What are accessories for heaters?

Accessories used for heaters are devices that enable a radiator to work. They are thermostatic radiator valve, bleeding valve and other installation accessories.

Where to buy accessories and radiator parts?

Accessories for heaters can be found in every hardware store. One can also buy radiator parts, for instance a radiator valve, on the Internet.
