I have an cb 5036 and a Baxi luna boiler that is used for DHW but is also plumbed up to be used as a furnace for the house.I never do use the baxi for heat. My heat guy hooked up the system so the owb heats water and pumps is to a heat exchanger and back to the boiler. Im not sure I need this HX and feel it may be causing my OWB to be less efficant. Im not sure if he did that incase I wanted to use Glycol in the OWB or what.
I have radiant heat in the basement and the first floor and a loop of base board upstairs. So I guess I have a closed loop. If I remove the HX then it would be an open system.
I wonder if the HX is to keep the system from getting air in it.
Any ideas?
