15) Health Benefits

With wet radiator systems the radiator surface temperature is the same as the circulating heated water. This is normally in the range of 80 to 85°C. Unless properly protected, these hot surfaces can present a risk to young children and elderly people - in care homes radiators can be a risk to patients with dementia.

The fact that there is much lower air movement with underfloor heating systems can be very important for people who have some of the more common dust allergies.

Underfloor heating also has the major advantage of depriving the common house dust mite of the one thing it needs to survive and reproduce - moisture. Without moisture the house dust mite will simply die. Underfloor heating maintains a much higher relative temperature in carpets and consequently reduces the amount of moisture available. In buildings heated by radiators the floor zone is much cooler and humid - ideal breeding conditions for the house dust mite.

Investigations have shown that underfloor heating can reduce the quantity of house dust mites by up to 80%, and even in summer when the mite population would normally increase the rate is much lower in buildings with underfloor heating. This is due to the very low numbers that survive the heating season.

The UK has one of the highest asthma rates in the world with 30% of our children suffering from it. Professor Duncan Geddes of the National Asthma Campaign states the following reasons for the increase, “It is also something to do with the way we are living in modern housing – little ventilation, damp housing, more carpets and more dust making asthma more common.”

Over nine million people in the UK suffer from asthma and each year 1,500 people die from it – which is half the number of those killed on the roads. But only £5m a year is spent on asthma research. The worldwide figures are frightening, with 300 million people in the world suffering from asthma and 255,000 people around the world died from asthma in 2005. Most worrying of all is that the number of sufferers is growing by 50% every ten years.
