Heating systems
vital that your chosen LST meets all three of these criteria. It’s also possible to opt for LSTs that are coated in anti-microbial paint and allow for easy, regular cleaning and optimum hygiene. High-output LSTs are used for spaces with a
larger heat demand. Ideal for care homes and buildings which aren’t subject to the NHS guidelines mentioned above, they boast an average surface temperature of 43°C. The best-performing models on the market use less water for improved heat transfer, quicker response times and overall better efficiency. Merriott, for example, is currently developing a model featuring a fin coil emitter inside the casing. These use less than 1L of water per linear metre (compared to 3L per linear metre in the case of standard radiators). Heavy-duty LSTs use extra sturdy casings for
applications where the radiator may be subject to external impacts (e.g. mental health units and high- security hospitals). These are available with a standard or fin coil emitter inside, for even higher heat outputs.
Radiant panels
Tucked away neatly in the ceiling, radiant panels bypass any burning or tampering risks altogether. They work by transferring radiant heat from above directly onto the surfaces inside a building, which then act as secondary heat sources to raise the indoor air temperature. This makes for much shorter heat-up periods and more accurate control of the system.
Offering superior design flexibility, radiant ceiling panels are a suitable solution for larger rooms that require high heat outputs, or for very small areas where there might not be enough wall space for a conventional radiator. As they eliminate potential points of ligature, they are also widely used anywhere where patients could potentially harm themselves with a standard, wall-fixed radiator.
Clinical radiators
These are usually found in non-NHS healthcare applications, such as private offices or laboratories. They operate at the same surface temperatures and heat outputs as conventional domestic panel emitters, but are easier to clean. Clinical radiators are typically panels or column radiators that have no fins, such as Merriott’s Primo, Precision and Profile types 10, 20 and 33 models. These are dirt- and dust-repellent, and can also be coated in anti-microbial paint for applications where there is a high risk of infection.
The full-package solution
With so many options to choose from for individual spaces – even within a single project – it’s crucial that professionals are ready with a good knowledge of the solutions available on the market. Those who do will be best placed to specify winning combinations for healthcare applications. Luckily, there are manufacturers that are making their jobs

easier by investing heavily to ensure they can offer a full range of emitter options – from small-scale LSTs to large-scale radiant ceiling panels for industrial use. By acting as a one-stop shop, those manufacturers will prove to be a valuable and reliable partner when it comes to navigating the sometimes rocky road of healthcare specification.
