multiple radiator explosion

I'll be calling a plumber tomorrow, obviously, but wanted to get some quick answers. I went to the vacant house I own today to check the gas meter and every radiator in the place had blown a 6-inch chunk out of itself. Several pipes were gushing, a backflow prevention valve in the basement was spraying. The place was a mess, of course. I've had the thermostat set on 50 all winter. Any ideas why this would have happened?

Sounds like the heat quit and the system froze. When thawed the water started flowing.

Busted Rads

I too think the place froze. Cast iron won't stand a lot of ice.

Any chance there could have been an extended power outage?

Was the boiler still running after the water loss?

I'm not sure how or why the heat quit, but the next question is:

What's the most cost-effective way to replace the radiators? Hot water baseboards? More radiators?

Replacing Rads

You really should go back with radiators. First, it would probably take a lot of baseboard to get the same amount of heat as you got from the cast iron rads. Secondly, mixing cast iron radiators & baseboard in the same zone usually doesn't work out very well due to the different heating rates. Baseboard heats a lot faster but cools a lot faster too.

If you can't easily obtain good matches for the cast iron rads (sizing, output and style), I'd strongly consider panel rads as the next best thing.

How is the system piped?

Single-piped. Got a call in to my plumber but we've got some fairly massive flooding in the area so I doubt I'll be hearing from him any time soon.
