then return, feed return keeping the two tees as close as possible together, no ganging! Otherwise you could get phantom flow, also the supply temps can/will get messed up. Start your highest temps. first DHW, then baseboard and then work down to the lower temps..radiant,etc. kpc

    secondary loop setup: hot water with zone valves

    Is it best to come off the primary loop (inch and one quarter) with secondary feed, then return, then feed, then return OR gang all the feeds together on the primary loop, followed by the returns ganged together, then the mixing valve just before enterrning the boiler returrn?
