Wrong on everything. You can't drain the hw heater unless you switch the valves unless you are trying to drain everything.
Winter bypass on your system is easy, just reverse each of the three valves. Then you can drain the hw heater tank. By switching the valves you can now use your water system without adding water to the hw heater tank.
