Cast Iron Radiator Ribs Removal: Tools & Techniques for Old, Large Radiators

Thanks, that is, such a strong advantage of cast irons is probably only their durability. Although there is a 10-year warranty on the Brugman panel radiator.

This is their main advantage, but not the only one (sometimes cast iron radiators that are 50, 60 or even 70 years old work). Another important feature is that they can be composed of any number of elements, i.e. the heating power can be carefully selected. Also in the case of high-pressure installations (over 6 at.), Panel radiators are not suitable, as they may not withstand (it all depends on the permissible operating pressure provided by the radiator manufacturer), while cast-iron ones withstand higher pressures (provided that the connections between the elements are sufficiently tightly twisted) and the highest pressures can withstand Favier radiators (as long as they are well welded). As for durability, for example, in Krakow there are buildings erected by the Germans during World War II with CO, in which cast iron radiators are heated to this day (back then there were such thick, very heavy ribs, with a very large capacity).

Some time ago, Viadrus released a new type of STYL cast iron radiators with a smaller capacity (0.8 l).

Only that there is nothing for free - the reduction (along with the surface) of the capacity translated into a radical reduction in power: 70 W at 75 degrees, while the cast iron TA-1 could reach the power in the range of 90-100 W (at 90 degrees) with these parameters. st. 120-130 W).
The Czech manufacturer recommends the use of STYL radiators for condensing boilers. Honestly, with such parameters I would be afraid to use them for heating at 55/45 degrees C. You would have to really oversize and ... significantly overpay.
And the old cast iron, if it is deaerated and desludged, works great with condensate. Tinplate and aluminum is cooler at lower temperatures than it.

Coming back to the topic: just unscrewing the plug in the old cast iron is quite an art. And twisting a rib is a real nightmare. I am talking about my experience with it, of course.

The T-1 has 125W at 90 degrees Celsius, while the TA-1 has a power of 150W at this supply temperature.
When unscrewing the plug, you need to remember about the direction of the thread (usually blind plugs had a left-hand thread - there is a thread on the Forum about unscrewing the radiator plugs). These "Style" radiators also have a 1 '' cap, whereas 5/4 '' would normally be used.

Many thanks for the large dose of knowledge. Regards.

Here you can visually compare both models and their technical data:

It will warm up the old topic, I have several radiators, one of them has 22 ribs, I want to divide all the radiators by 2 ribs to take for scrap, I have no key to unscrew it, it is also not possible to move these radiators to other places (too heavy), it is best to it was something to cut just the question with what? (I have an ordinary small grinder, can it help? what discs to buy?)
There are 92 ribs in total - if one weighs about 6 kg, I have 552 kg * 0.68 PLN (1 kg) 375.36 PLN - it's even worth taking away
But how to undress it? (one person)
Or maybe a tinker and a hammer? split it like this? can whole ribs come crashing down?

The grinder should cut (sometimes they do this to take the old, large heater away for scrap). The biggest one in the picture has 25 ribs and those old ribs are thick-walled and probably weigh more than 6 kg each. You also need to add the weight of the radiator nipples). By the way, are these radiators damaged (e.g. cracked)? Maybe somewhere where you are building something or installing central heating that would come in handy (after rinsing the limescale). Cast iron radiators are durable - sometimes they work for 100 years. Unscrewing into individual ribs may be unrealistic, because after many years the threads may be completely seized.

I do not know the condition of these radiators (they have been in the basement for many years), they want PLN 0.68 per 1 kg on the scrap, no matter what form I will deliver them to them ... so I'm going to get a tinker and a hammer and hit them in the places where the ribs are joined hammer to junk ... maybe we can "split" them :)

I would sell them for the price of scrap metal, but there are many ads on olx, but somehow there are no applicants ...

You combine like a horse uphill, I have recently replaced cast iron radiators all over the house, some large, 22 ribs, a plumber (my son's friend) with a big hammer "disassembled" them into pieces in a few minutes, of course, then they were only suitable for scrap, cast iron is extremely brittle material.

I will do that too, a big hammer and I will pound between the ribs to separate them. I thought there was a better patent for it ...

BEST

Just for information, I wanted to add a photo of what a screw that connects two ribs looks like (I have not found such information anywhere on google, so maybe it will be useful to someone ...)





For unscrewing, I use a majolka that fits perfectly as a "key" and I wind a wrench on the master + I put a 2-meter pipe on the wrench ... and somehow it even goes "

The point is what a coupler that holds "two ribs" together looks like, this information may be useful for some ...
