Hot Water Radiator Leak (by MMIT [VA]) Posted on: Feb 7, 2024 10:01 PM
Message:

I have a large house with hot water radiator heat that uses cast iron radiators.

A couple radiators have developed small leaks between the jackets.

These radiators use press fit sleeves between each jacket.

There is no gasket between the jackets.

Is there some type of gasket material I can use to seal up the leak? Some type of perm-a-gasket?

Thanks

There maybe water entering system which causes oxygen then the rust will start. The water should black where no oxygen. There are two options here one look at internet and market place for radiators where it may be possible to buy used. Another option is to install a copper or metal finned baseboard radiator where longer or using two levels of fins. Can go into the Slant Fin website where can match pipe diameter. Unless trying welding where the radiator may not hold up. For a forced hot water system that uses a circulation pump a Spiro vent air and dirt separator is recommended at output of boiler where air is separator then once in while valve is opened on dirt separator. If repair is delayed then more fresh water will enter system which is going cause more problems where can even cause heat exchanger on boiler to fail. It like the time I keep putting radiator sealer in radiator where eventually had to replace radiator. The European panel radiators are really expense. --207.236.xxx.xxx

These videos show an epoxy being used to fix a pin hole leak in a cast iron radiator as well as to seal a leaky joint. You might try doing something like this. IMO the key takeaways are to clean the areas well & to use a marine grade epoxy that can be used under water.

Our home is also heated with such. It's a fantastic heat and I would not replace it. However I would call in the right service company and let them fix. This may be the most important step in maintaining the system for many years to come. --172.59.xxx.xxx

Here is a hack that I have used with small holes in my radiator in my car:

If they are only pin hole size leaks, can you open up your exaptation tank and put in a 1/2 cup of COURSE black pepper inside it and seal it back up with water.

That black pepper will get pushed through the system and get trapped into the largest spaces you have inside your lines.

You may also need to burb your radiators after doing this. The same water line that you use for ice makers work great on burping it if you do it to your highest placed heaters (second or third floor?) first.

I love water heat - for an owners home, maybe not a tenants home --24.101.xxx.xxx
