How radiators are damaging our health

Rotarad are proud to be partnered with Keele University, working together to collaborate research findings which identify the relationship between dust and common health problems such as respiratory allergies and asthma.

Together we have identified that dust is becoming an ever increasing problem, as the list of harmful cases it has been linked to is expanding. This is an issue we have found the majority of people are simply unaware of.

Our main goals are to help raise awareness of these issues, and we are aspiring to help introduce new commercial standards which will ultimately reduce the chances of our health being affected by dust.

How household dust is affecting us:


Patients being treated for asthma in the UK

Over 1000

Annual deaths (equating to 3 patients per day)

£1.1 Billion

Approximate cost to the UK NHS annually

Dust emitted from Radiators

Dust from unclean hospital radiators has been linked with the spread of disease

Sudden Infant Death Syndrome

Poor indoor air quality has been linked with SIDS

So what exactly is the problem?

The attempts to save energy and reduce heating costs over recent years have led to the development of technologies such as Double Glazing windows, advanced central heating systems and advanced roofing insulation. However this has also had a negative impact when it comes to reducing levels of dust.

Central heating radiators create ideal conditions for dust mites, mould spores and microbiological infections to flourish, creating higher levels of allergens that are then circulated via heat convection which ultimately create poorer indoor air quality for us, especially within the winter months.

Research by Arcc Network shows cases of respiratory infection allergies and asthma have risen significantly because of newer stringent green building regulations and the rise in refurbishment of older properties, reducing ventilation and increasing condensation, resulting again in poorer air quality.

The dust mite is the most common cause of allergy symptoms in the UK. It is one of the most potent triggers of allergy reactions and a common trigger for rhinitis, asthma and eczema. Allergy symptoms include sneezing, watery eyes, coughing and wheezing.

The dust mite is found in almost every human habitat, but it is invisible to the human eye. Its nests are made in bedding, curtains, carpets, soft furnishings and soft toys, and can be present in the home all year round.

NHS Choices reports that indoor allergies are very common and that 10-20% of the population now has an indoor allergy. The average person in the UK spends 92% of their time indoors.

Home fever” is a term used by Allergy UK to describe out-of-season hay fever symptoms. It is triggered by allergens such as dust mites, moulds, cleaning products and pets that are present in the home or office. Allergy UK estimates that at least 12 million people are allergic to their own home.

Radiators contribute to the problem:

  • Convection

    There is a high probability that a radiator which is not periodically cleaned is circulating allergens into the home environment through the heating convection process

  • Installation

    Allergens falling from fabric curtains accumulate within radiators installed below windows, and become a significant health risk once released when central heating systems are in use

  • Dust

    The rise in allergy cases over the autumn and winter period is likely down to the spreading of dust containing allergens through increased usage of central heating systems

  • Hospitalised

    At least 200 people are hospitalised because of Asthma every day in the UK, a total of 73,000 people a year. “Home fever” is a key contributor to this

The Elephant in the room…

We know that radiators aid the circulation of allergens and bacteria within buildings, but we have yet to find anyone talking about this problem in detail

It is a requirement within NHS facilities that all parts of a radiator must be visibly clean. We would like to see this standard become adopted across all commercial buildings and households

Cleaner Radiators, Better Health

The Rotarad radiator conversion kit allows the radiator to be dropped away from the wall, allowing clear access for faster and more thorough cleaning

It is widely compatible and can be easily installed with new radiators, or retrofitted onto existing ones
