Most Common Types of Radiators

  • Panel Radiators
Panel radiators are one of the most common types of radiators found in residential homes. They consist of a single or double panel connected to a series of fins that help distribute heat efficiently. Panel radiators come in various sizes and can be mounted on walls or placed on the floor.
City Plumbing recommends central heating radiators and LST radiators all with a selection of single, double, and triple panels available.
  • Column Radiators
Column radiators have a classic and elegant design, with multiple vertical columns that provide a larger surface area for heat emission. These radiators are ideal for larger rooms or spaces that require higher heat output. Column radiators come in various materials such as cast iron, steel, and aluminium.
City Plumbing recommends superb column radiator choices from brands including Myson, Stelrad, and Towlelrads.
  • Towel Radiators
Towel radiators serve the dual purpose of heating your bathroom while also providing a convenient place to hang and dry towels. These radiators come in various sizes and styles to complement any bathroom décor. Towel radiators are a popular choice for bathrooms due to their functionality and space-saving design.

These radiators are easy to install and operate, making them ideal for rooms that need additional heating or where traditional radiators are not feasible. Electric radiators come with programmable settings for personalised comfort.

  • Designer Radiators
Designer radiators offer a stylish and modern alternative to traditional radiators.

Designer radiators can be a focal point in any room and are available in both vertical and horizontal designs.

  • Underfloor Heating
Underfloor heating is a popular choice for homeowners looking for a discreet and efficient heating system. This type of heating involves installing pipes or electric heating elements beneath the floor to radiate heat evenly throughout the room. Underfloor heating provides a comfortable and consistent temperature without the need for traditional radiators.
City Plumbing recommends a range of electric and water choices for underfloor heating.

Radiator Types Explained

  • P1 (also known as Type 10): This is a basic radiator with a single panel and no convection fins. It's the most compact and affordable option, but it also has the lowest heat output.  
  • K1 (also known as Type 11): This radiator has a single panel and one set of convection fins. Convection fins are metal plates attached to the back of the radiator that help to increase the surface area and improve heat transfer. This makes K1 radiators more efficient than P1 radiators.  
  • P+ (also known as Type 21): This radiator has two panels and one set of convection fins. It offers a higher heat output than K1 radiators and is a good choice for medium-sized rooms.  
  • K2 (also known as Type 22): This radiator has two panels and two sets of convection fins. It's the most powerful type of compact radiator and is ideal for large rooms or rooms with high heat loss.  
  • K3 (also known as Type 33): This radiator has three panels and three sets of convection fins. It's the most powerful type of compact radiator and is ideal for very large rooms or rooms with very high heat loss. 

Make an Informed Hearing Choice for Your Home With the Right Radiator 

Choosing the right type of radiator for your home is essential for ensuring optimal heating efficiency and comfort. When making this purchase, it's important to consider the size of the room, the level of insulation, and the desired temperature.
You should also make sure that the radiator is sized correctly for your boiler. If you're unsure which type of radiator is right for you, it's always best to consult with a qualified heating engineer.
