How Do LST Radiators Work?

UPDATED: This blog post about LST radiators was updated on March 2020 to reflect more information and latest pictures.

To bring safe heating solutions to the healthcare, education and commercial sectors that we work with, Contour supply LST Radiators to ensure that low surface heating protects service users from burns and scalds.

But how do they work?

Contour has produced a blog post exploring how LST Radiators work, and how the provision of safe heating can protect everybody in a space.

LST Radiators: Safety First Design

LST Radiators are about bringing the overall surface temperature of a radiator cover down, so that, should a child or vulnerable person come into contact with it, they are at a lower risk of injury.

Did you know?

According to NHS Hospital Episode Statistics for England, the CIPHE has found that from 2017-2018:

962 finished consultant episodes were allocated for individuals treated for burns caused by contact with heating appliances, radiators and pipes. Source.

The Convection Process

LST Radiators use a convection process to heat up a room. It is one of the most effective ways to safely heat up an area whilst keeping the heating system at a low surface temperature.

The boiler will pump out the water at 80°C, which then travels through the system to the radiators. Because heat dispersal needs to be quick in LST Radiators, the water temperature should drop by at least ten degrees by the time it gets back.

LST radiators work by pulling in air from the bottom grilles. This intake of air then rises through the cover, where it warms up-thanks to the hot water passing through the system.

The warm air is then emitted back into the room via the top and front-facing grilles.

The convection process sees that hot air rise into the colder spaces in the room-which is usually the middle-and the spaces furthest away from the radiators.

Once in these cold sections, the hot air cools and then sinks, where it then begins to warm up again and re-rise, causing the room to stay at a steady, comfortable warm temperature.
