My furnace heats my house with infloor heating also my DHW. The furnace used to have a coil for the DHW now it has been removed and I have a 80 gallon indirect water heater tank combined with my solar heat. So now the boiler is controller with an aquastat in the water tank. How should the boiler control settings be changed now that the water in the furnace doesn't heat the domestic water coil like it used to. I don't really want the boiler to maintain its water temp when it's not needed. Thanks.
