What is Underfloor Heating?
Traditional radiators generate an upward stream of hot air through convection, causing the air at ceiling level to be much warmer than at floor level. Underfloor heating systems also operate through convection but essentially turn your whole floor into a giant radiator, ensuring consistent heat throughout your home and allowing you to feel the heat benefit immediately.
Plastic pipes concealed under the floor of a property or room allows heat to radiate upwards when warm water circulates throughout. This underfloor placement ensures that heating is evenly distributed whilst avoiding the need for visible radiators taking up valuable wall space.
As the surface area of underfloor heating pipes is many times greater than that of a radiator, the temperature of the water in the system is not required to be at such a high heat – with traditional radiator systems drawing water from your system at 70-80°C and underfloor systems draw water at 45-65°C.
Due to this reduced temperature, underfloor heating works particularly well when paired with a heat pump installation. The heat pump does not have to
work as hard to produce high temperatures, less electricity is needed to power the heat pump and therefore a greater cost saving is achieved. The two work perfectly alongside each other to provide a constant temperature throughout the day.
Underfloor heating is also safer, with no chance of young children burning themselves on hot radiators, and is recognised to be healthier, especially for asthma sufferers, as it reduces airborne dusts. Furthermore, in buildings heated by underfloor systems you can normally expect to be able to turn your room stat down by 1-3°C yet retaining the same thermal comfort as radiators operating at the higher temperature.
