I moved into a condo a year ago. I have never had as many leaks and floods in my condo in a years time. Five of the floods were in the first month of moving into the condo.I think this system is the worst system in the heating world. I am now just today putting up with a wet floor for the 15th time.I am currently looking for somewhere else to live and if I see a Apollo heat system will run out the door screaming.
