radiators with heat exchangers improve energy efficiency

Radiators with heat exchangers are becoming an increasingly popular choice for anyone installing an energy-efficient heating system. Unlike traditional radiators, which rely on a water-based cooling medium, these radiators use fans to circulate air around the exchanger tubes. This allows them to be used without restriction, for example, if the plumbing isn’t accessible.

But what is the difference between a heat exchanger and a radiator? And which one is right for your project? In this article, we will take a closer look at both types of heat exchangers and explore their benefits and drawbacks.


Why is a Heat Exchanger?

A heat exchanger is used to transfer heat between the heat source and the heated fluid. Heat exchangers are used in both cooling and heating processes. A solid wall may separate the fluids to prevent mixing or being in direct contact. There are two types of heat exchangers: radiator-type and lamella-type. Radiator-type heat exchangers use water as a cooling medium, while lamella-type exchangers use air. There are 3 main benefits of using a heat exchanger in a heating system:

  • They can improve energy efficiency by transferring heat to places where it is needed most.


  • They're a versatile choice that can be used in a variety of heating applications.


  • They are an affordable choice that can save you time and money on installation costs.

Lamella heat exchangers consist of an outer tubular shell surrounding an inside bundle of heat transfer elements. These exchangers are made of parallel, welded, thin plate channels or lamellae (flat tubes or rectangular channels) placed longitudinally in a shell.

The radiator-type heat exchanger is a series of tubes that are filled with a heat-transferring fluid. The hot fluid passes through the tubes and transfers its heat to the fluid in the tubes. The cooled fluid then passes through the tubes and transfers heat to the surrounding air. The radiator-type heat exchanger is an efficient way to transfer heat from one fluid to another and is commonly used in cars and trucks.



Why is it Important to Specify an Energy Efficient Radiator?

Radiators are a very energy-efficient way of heating a room, particularly in a commercial setting. The energy-efficient radiators that are available on the market today can save end-user money on their energy bills. Here are the things that you need to consider when you are looking for energy-efficient radiators:

  • The size of the radiator. The larger the radiator, the more energy it will use.


  • The type of material that the radiator is made from. The most energy-efficient radiators are made from aluminium, copper or Zintec Steel.


  • The thickness of the radiator. The thicker the radiator, the more energy it will use.


  • The price of the radiator. The more expensive radiators will usually be more energy efficient than the cheaper ones.


  • Using a heat exchanger. Radiators with heat exchangers are more efficient than traditional radiators, allowing you to save energy and money on your heating bill. They can be used in residential, commercial, leisure and health care, making them a versatile and energy-efficient heating system.

Choosing an environmentally friendly heating system will also help you reduce the carbon footprint of your project. Designing these systems can be the difference between achieving sustainability accreditations or having a building that is bad for the environment and the wallet of the billpayer. Get the peace of mind that comes with knowing your project is being heated in the most environmentally friendly way possible.


Energy-Efficient Radiators with Heat Exchangers

If you are looking for an energy-efficient, cost-effective radiator to install on your project, then you need one with a heat exchanger. A lamella heat exchanger is the best type available on the market today.

All the radiators in the Sovereign range are fitted with a lamella heat exchanger which saves the end user money on their heating costs. It also reduces the impact on the planet thanks to its air vent, providing low water content, yet high energy. Sovereign is more efficient than traditional radiators, so is a sustainable choice for all applications.
