: Of course, you have to find a way to make the heat go where you want.......Steam systems go to the delivery location "for free"....hot water systems do not....That is why steam has an advantage ove hot water systems !!!
Have you considered the impact and cost of circulation pumps on your existing system ?? These pumps can be of significant horsepower and will contribute significantly to a yearly opeating expense.
Is this even feasable with the age and configuration of the piping contained within your building ? If the building is multi-story, then the pumps will have a significant head to operate against (read high electric bills..)
My opinion only
