Circulator - Boiler - Expansion Tank
I just moved into a (new to me) house. It used to have a gravity system that was converted forced circulation system. The previous owners about two years ago put in a new boiler. The setup in the direction of flow is Circulator - Boiler - Expansion Tank (bladder style, no air eliminator the tank is just connect to a tee on the line). The system seems to work fine, no noise and I have heat everywhere.
Could this cause issues in the future? Or "if it is not broke do not fix it".
Thanks for your opinions!
