I am wondering how to supply hot water to my heating zones if my storage tanks are cold. Heres the scenario. If my boiler is cold and my tanks are cold and I make a fire with a zone calling for heat,do I have to wait until my tanks charge to be able to deliver hot water to the coil in my forced air furnace? I have a aqua stat on the boiler that turns on the boiler circ when boiler is hot. I have a grundfos alpha that supplies 3 zones on zone valves. I have a aqua stat threaded into the top portion of my pressurized storage and a aqua stat threaded into the bottom of my propane water heater equiped with sidearm heat exchanger. I dont understand how to control my pumps/zoning if my tanks are cold? Do I have to wait until my tanks have useable water temps or is there a different way? Thanks fellas.
