I just did a search on a Ridgid ProPress crimper. I found one for about 1600 bucks, so they ain't cheap.
Spiro, the radiator water, and potable water, are completely separate systems. There is a tank within a tank. The inner tank is the hot water for drinking and showering and such. The boiler heats water for the radiators and circulates it through the jacket between the inner and outer tanks. That indirectly heats the water in the inner tank. Then, if home heat is needed, a circulating pump sends the water in the jacket between the tanks, through the radiator system. So the two systems are concentric, but completely isolated from each other. -- Blue skies. Dan Rossi Carnegie Mellon University. E-Mail: [EMAIL PROTECTED] Tel: (412) 268-9081
