INTRODUCTION TO LOW TEMPERATURE HEATING

The suggested range for a comfortable internal temperature is between 19 and 25°C. Traditional radiators must use water at temperatures of anything up to 80°C to ensure that the farthest corners of a room are warm. However underfloor and convection heating systems can utilise water at much lower temperatures. This leads to significant fuel and cost savings because heating water to lower temperatures requires much less energy.

The chart below illustrates the decline in heat pump efficiency (COP) when heating water to higher temperatures:

The coefficient of performance in the 35 to 40°C range can be as much as twice that of higher temperatures. Fortunately this is the range in which underfloor and convection heating systems work best.

These systems provide an even spread of heat throughout the building while using far less energy to do so. Hot and cold spots are eliminated and draughts can be minimised. Healthcare facilities and households with young families will see particular benefits as there are no hot surfaces that can harm infants, the elderly or infirm.

While low-temperature distribution systems are ideal for use with renewable technologies such as heat pumps and solar thermal collectors, they can also save up to 20% on fuel bills when used with oil or gas heating systems. For those wishing to retrofit their home, office building, hotel, commercial premises, etc., to incorporate renewable technologies, Dimplex SmartRads provide an ingenious and attractive way to cut costs and save energy.

With years' experience designing and installing heating distribution systems, Geothermal Solar are the first choice for quality, reliability and innovation when it comes to heating distribution.
