Are Old Radiators Efficient? [SOLVED!]

Radiators are often taken for granted as a feature of your home, expected to perform their duties without any extra care or attention ๐Ÿ™Œ If you’ve recently moved into a property, it’s possible that your radiators have been installed for decades without receiving proper maintenance ๐Ÿ‘ It can be easy to forget about radiators when you are renovating or restoring your house ๐Ÿ™Œ You should replace your radiators unless you are moving to a new home. This allows you to choose more energy-efficient radiators, while still keeping the property looking great. [1]
According to British standards, radiators should be installed on the exterior wall under windows whenever possible. An external wall is easier to mount and these are usually the coldest areas of the roomThis will offset the loss of heat and make the space more comfortable. Curtains above windows may not shield the radiator. Heat will also be lost through exterior walls and windows. This heat loss can be reduced by installing a radiator shelf and reflective materials like Radflek above it. GreenAge subscribers can receive a 20% discount with the offer code TGA20.

However, it was easy to decide where a radiator should be located a few years back. Typically, the radiator would go in the area that is the coldest, usually on an exterior wall or under a window. These days, however, most homes have double-glazed windows and are better insulated. Installing a radiator in this area may not prove to be efficient. This is especially true if it is hidden by long draped curtains; as this blocks the heat from the radiator, which was discussed in our recent blog post โ€˜Have you ever thought about putting radiators in unconventional places?โ€™ Luckily with all the variances in size and heat output options modern radiators give you, you now have endless locations you could consider. You can even have two radiators in your room instead of one and half the heat output for each as we discussed in our recent podcast โ€˜Getting hotter and hotter room by roomโ€™.

Cast iron conductivity is also higher than steel. Therefore, heat transfer from cast iron radiators into the room has been shown to be much more efficient than steel. The blast from steel tends to be louder than that of iron. Heat in a short space Cast iron will radiate ambient heat for a longer time than cast iron. Cast iron retains heat longer than steel because it has higher levels of carbon. Cast iron’s high carbon content makes it possible to retain heat for a longer period of time than steel. Heat to diffuse through the cast iron evenly, which means the surface conducts heat more efficientlyThe cast iron radiator is therefore more energy-efficient. [4]
