    I use a one inch Danfoss esbe 4 way valve to control the direction of flow to/from my storage tank. This also requires a esbe motor if you want to do the switch over automatically.
    This method works very well.

    See here ->

    Another 4 way valve was once used to provide low temp boiler protection, but that has been removed. I now provide low temp boiler protection by controlling the flow in the Primary loop.

    If you have any difficulty finding a 4way valve contact me via private email. I have a used 1 1/4" and a few new 1" Danfoss esbe 4way valves.
