Unfortunately, this also stops any heat, but it's July - you have plenty of time to get it repaired.
Sorry George, but both the supply and return MUST be clamped off. If you just clamp the one, the fluid/water will just go through the coil from the other sidel. A partial draining must be done (when the coil is removed the fluid will drain to its lowest point so drain it to below that lowest point) bnelson1970, your going to have quite a job replacing the coil, good luck! Your on your way as it is, just take a lot of pictures so you can get it back together as reversed to how you got it apart.
