I posted this in another forum, so if it looks familiar, that's why. I assume "residential" is the right location, if not feel free to move it.
OK here's the deal. I have a water boiler system in one of our houses (rental). Anyhow during an unoccupied time, some of the radiators busted, presumably from freezing, but not sure.
A few things have come up in the attempt to repair this:
1) Where in the hellation do you find water radiators. Not the old cast iron type, these look more like car radiators, than home radiators. They have what looks like 3 tubes (copper??) running through a set of fins, manifolds on the ends (which is what busted, btw) This whole works sits inside of a metal box frame. Websites? Any ideas at all?
2) We found some used, older style (the old cast iron) radiators.(picture below), I think they are sectional and can be broken down to shorter lengths...???. (speaking of that, how do they come apart? What's between them? O-rings, gaskets...what?) Anyhow, is there any harm in mixing the two styles together? I can't imagine why it would matter, but I'm not an HVAC expert.
3) Someone told us to fill the system with antifreeze (I assume they meant 50/50 but I don't know) instead of straight water. Good idea? Bad idea? I can come up with the reasons TO do it myself, but is there any reason NOT to do it?
TIA for any help. Any ideas, suggestions, thoughts at all are welcome. IN the mean time, I'll be searching past threads and topics for any ideas.
