I am needing to move the hot water heater into a space that is shorter than where it currently resides. It will have about six inches of clearance above the tank. So, due to this, I need to move the expansion tank. Can the tank be moved to be on the side of the hot water heater?
Does the expansion tank have to be above the top of the hot water heater?
Also, the copper pipe connecting the expansion tank to the heater, is welded together. I'm not comfortable with my copper welding skills. Are there other options for making this connection?
Unfortunately, after looking it over, I am not going to have any room for the expansion tape to go on top of the hot water heater. Checkout the diagram I've posted below. The black lines is the wall. This is how, in my mind, I will set it up. Question, how should I secure the lines going up to the water heater and the expansion tank? Anything else I should think about?
Do the vertical water lines need to be secured to anything? I could nail in a 2x4 to clip them to. For the expansion chamber, If I mount it horizontally on the side, do I just use some type of strap to take the weight off of it? Can it be strapped down directly to the floor joist?
