Disadvantages of Traditional Radiator Heating

• Wide Variation of Temperature - cold feet, stuffy head
• Cold Draughty Floor
• Higher Running Costs - increased fuel bills
• Increased Risk of Allergy Problems
• Ugly Radiators - dangerous temperature
• Annual Boiler Maintenance - additional cost
• Typical 1 Year Guarantee

We have all grown to accept radiator heating even though this form of heating have many disadvantages.

The initial high cost of the installation is followed by continual annual boiler maintenance charges. The more sophisticated and higher the efficiency levels of boiler designs become the greater the maintenance costs. High efficiency, very often falls rapidly leading to greater running costs. Most boilers have only a twelve month guarantee.

Radiators produce very high unsafe temperatures at local areas of the room. The effect of the high temperatures create large thermally induced air movements around the room.

Immediately above the radiator the heated air rises rapidly towards the ceiling. This air movement entraps dust particles and it is this affect that causes staining to the rooms dιcor. High levels of dust in the air can severely affect asthma sufferers.
As the heated air moves across the ceiling it gradually cools releasing its heat into a trapped layer of high temperature stale air immediately below the ceiling. This layer of stale hot air gradually increases in volume and it is this stuffy air that we feel about our heads, making us feel uncomfortable.

Continuation of the thermally buoyant air movement eventually meets the cooling effect of the windows and as this air cools rapidly it sinks quickly to the floor. Upon reaching the floor the cool air is effectively sucked across the floor towards the radiator where it starts it cycle again.

It is this cool air movement across the floor that we feel around our legs, making us feel cold. Cool air is also trapped behind chairs and furniture and as this restrained air cools further it will escape around the furniture and combine with the cool air flow across the floor.
When our legs are chilly, we feel colder, and we tend to turn the thermostat up to counteract the feeling of cold legs. Running the heating system at a higher temperature leads to increased energy consumption.

As our buildings become increasingly space conscious the ugliness of radiators and the space they consume become more significant.
