hot water heater
I have an old cast iron boiler with the summer -winter hookup. The heat is by steam. I would like to install an electric hot water heater so I don't have to run the boiler in the summer. I have been told that sometimes when that is done the seals on the boiler will go bad and will be costly to repair. How can I still install a hot water heater? Can I pipe it in so the water goes through the hot water heater and also through the boiler, perhaps preventing any seal damage?

Ask them What Seals? I wouldn't worry about it at all. There are millions of hot-water boilers that are turned off in the summertime, mainly in areas where natural gas is available and most people use separate, stand-alone water heaters.

I had a boiler that would leak water on the floor when I would shut it down. The metal would contract when it got cold, and it leaked at the seams between sections. No problem when warm.

Yep... the problem is seen more often with boilers that have spent their life as 'warm start' units, then at some point converted to 'cold start'. Also, boilers assembled with 'push nipples' versus 'elastomeric seals' seem less prone to the problem.
