Wavin has worked with LCPDelta to create a whitepaper that demonstrates how efficiency gains are achieved using basic physics, supported by laboratory and field trial data.
In this post, we highlight key findings in the Whitepaper including how underfloor heating (UFH) can deliver superior thermal comfort at a lower air temperature compared to radiator-based systems, and how the reduced heat demand can be provided more efficiently when appliances are allowed to operate at lower flow temperatures. All this without losing comfort.
Heat Loss
The biggest mistake that people often make is assuming that their level of comfort controls the thermostat, when it is the air temperature that controls the heating system. Subsequently, when we feel cold and boost the heating, we experience increased heat loss.
Whitepaper finding 1: A uniformly heated floor area overcomes the problem of cold or hot spots, eliminating potential damp issues and enhancing comfort.
Radiator Systems
The most common method of heating our homes is through radiator systems. However, when increasing the temperature, radiators may cause inefficiencies. The positioning of radiators creates a steep temperature gradient between the floor and ceiling, causing separation. Warm air from the radiators rises and in turn, cool air falls, suggesting that the thermostat is sensing only the cool air. As a result, occupants feel discomfort and inadvertently set a significantly higher air temperature than the desired average room temperature. Thus, consuming too much energy and losing money
Underfloor Heating
UFH can assist in reducing inefficiencies providing a key advantage over radiator systems.
Whitepaper finding 2: The large surface area of UFH creates similar levels of comfort at lower temperatures.
The thermostat will better reflect the desired temperature due to a lower temperature gradient, resulting in a more even distribution of heat. Heat loss is therefore more in line with that expected and a higher level of comfort can be achieved.
