Getting new radiators for your house can make a massive difference to the overall temperature of your home. Older radiators are not as efficient as newer ones mostly down to improved designs.
Panel radiators are most commonly used. As well as radiating heat they also convect the heat. Behind the panels are grilles, which convect the heat. The easiest way to explain would be to say that the grilles act like chimneys, with the cold air at the bottom, passing up through the grilles coming out of the top hot, thus distributing the heat better. Older radiators do have grilles, but improvements in design have seen a great change in effectiveness.
Steel Column Radiators
Steel column radiators do cost more to buy than panel radiators, but do tend to give more heat output for longer. This is due to the thickness of the metal used and the amount of water content which enables them to hold onto their heat for longer. They are different in appearance to panel radiators and can be used more as a feature.
Cast Iron Radiators
Cast iron radiators give a tremendous amount of heat back. They hold onto the heat for up to a couple of hours after the heating has been turned off. They are more of an investment for your home and are available in many styles, colours and finishes ranging from a modern look to the more traditional variety. Cast iron radiators are a great focal point for any room!
