Problem with Steam Boiler and Indirect Hot Water Storage
Help?! I have a fairly new steam boiler with an indirect hot water tank. When I take a shower and pull hot water for 10 minutes, the boiler runs to replace the hot water, but also creates steam and heats the radiators (very hot) So in the springtime, my house turns into an oven. Is there a problem with my heat or a problem with my hot water tank. Thanks for anyone's help.
Sound like a control issue. There is supposed to be an aquastat for the indirect that limits the boiler temp to 180-190° so it doesn't steam and heat up your home as you describe. Any pics? Where are you located?
Is this the first time you have used the indirect when heat was not needed? The boiler has to maintain temperature, for your domestic water. That can be done with a Honeywell 6006,which would open on temperature rise.The aquastat on the indirect would close on temp. fall, to circulate boiler water through the indirect coil,and heat your domestic water.If the aquastat on the indirect fires the boiler like the thermostat you are going to make steam.Where does the boiler water leave the boiler to go to the indirect, and where does it return to the boiler?
