Cast iron radiators are a significant investment and if they are working efficiently, they will provide a powerful and reliable source of heat in your period house. If however they are not working properly and contain air pockets which prevent them outputting their full heat capacity, the warmth they provide will be much lower than the level of heat you may require in the depths of winter.
This is a simple guide about how to clean cast iron and column radiators. These radiators can be tricky to clean with their vertical columns with narrow gaps in between them, which attracts dust and dirt. A small cast iron radiator with 12 columns can take a good half an hour to clean but this is not something that needs to be done every week. If you are not careful dust can really accumulate without you realising leaving a very mucky…
Franz San Galli invented the heating radiator in St Petersburg between 1855-1857, although in actual fact the taste for radiators in Great Britain did not gather pace until the early 20th century. The earliest radiators used steam which caused numerous issues and was responsible for many a scald injury; the introduction of hot water radiators made them much safer and therefore more popular.
A BTU (British Thermal Unit) Calculator or Heat Output Calculator is a really useful tool when choosing a traditional radiator for your period property. A BTU Calculator helps calculates how many BTUs are required to heat a given space or location and therefore helps determine the right sized radiator for that location. A Heat Output Calculator is exactly the same thing measuring the Heat Output required to heat your rooms.
Early man would build a fire in the centre of his combustible hut or damp cave. Even when coal came into regular use the efficiency of each open fire place meant that most of the heating went up the chimney, (it would have been warmer to sit on the roof), with added danger of chimney fires or sparks causing the home, especially dwellings with a thatched roof, to burn to the ground.
