Low surface temperature radiators (or lst radiators) are an alternative heating product designed to not exceed a surface temperature of 43oC. 

With this recommended temperature set by the NHS, lst radiators are ideal for use in hospitals and care homes as well as places such as schools and nurseries where children could easily harm themselves on hot surfaces. 

Despite their importance, understanding the pros and cons of any product, including lst radiators needs to be considered.

Pros of LST Radiators

LST Radiators Are Safe

LST radiators provide a low surface temperature that offers protection against the risk of burns to service users in a space. Unlike traditional radiators, they do not exceed a temperature of 43°C which makes them much safer in a variety of environments. 

LST Radiators Have Faster Heat Generation

Low surface temperature radiators heat up a room quicker than other heating solutions that are considered for healthcare and educational spaces such as underfloor heating. They heat a space using the convection process which creates a consistent room temperature faster.


Easier Heat Regulation

When a room reaches a certain temperature, and you feel that you would like to increase or lower it on the TRV head some radiators can take a long time to take effect. Underfloor heating, for example, can take up to a full day to have an effect.

Contour LST Radiators regulate the heat with rapid effects, making the room at a consistently comfortable temperature for you. There is also more control over heat regulation with an LST radiator because of the surface-mounted TRV heads.

LSTs Are More Cost-Effective Than Other Heating Solutions

Compared to other heating solutions such as underfloor heating or radiating ceiling panels, LSTs are cheaper to install. 

LST radiators are also easier to clean with RotaRad kits that reduce the time it takes to clean a radiator from 30 minutes to 10 by one person.

As the healthcare and education sectors are often affected by budget cuts, this is a huge benefit.

Cleaning of LST radiators is made easier as you can see in the video below. The covers drop-down with a simple turn of the lock and provide cleaning teams with access to maintain hygiene levels. 


Flexible LST Radiator Design

LST radiators can be installed wherever you need them in space. Underfloor heating limits your options one where things are placed within a room. With an LST radiator, you’re free to organise a space however best suits you and those using the environment.


LST Radiators Are Much More Robust 

When underfloor heating or radiant panels break down, even small parts of the system, the entire structure is rendered useless. They damage easily and require a lot of maintenance to keep them running.

LST radiators are more durable, lasting longer than other heating solutions and require less maintenance over time. Contour LST radiators come with a 10-year warranty, for extra assurance that no matter what happened; you are protected. Our radiator covers also feature a 5-year warranty.


Cons of Low Surface Temperature Radiators


Dust Traps

Traditional LST radiators can become dust traps, making them a risk for infection. Contour has counteracted this with our range of DeepClean LST Radiators.  They come with BioCote® anti-microbial technology to inhibit the growth of bacteria by up to 99.9%, while the lst radiators themselves are also much easier to clean. 


Installing traditional LST radiators onto a wall does take up space. In corridors this can be problematic for moving hospital beds or where children are moving around.

Contour’s LST radiators are bespoke designed to suit the space, making them more convenient for you. We can even offer a vertically fitted option if wall space is limited.


Radiators were not initially designed for aesthetic purposes. Some people worry that installing LST radiators will make the space seem unsightly.

As part of our bespoke design policy, Contour can work from any four-digit RAL code. We offer a range of colours to suit any environment. This means maintaining an aesthetically pleasing look in a space while providing low surface temperate heating solutions.

LST Radiators For Your Environment

There are many benefits to installing LST radiators into a space. They are safer than standard radiators with their low surface temperature design. They are faster at heating up and regulating the temperature and are cheaper to install than underfloor heating.

While traditional designs have some drawbacks, Contour has produced a range of LST radiators that counteract this. We offer DeepClean options, bespoke design and a range of colours to suit any environment.
