: To get improved flow, you could use one lower element port as a port for the piping and the two top ones with the dip tube removed from the cold line (some contain check valves which restrict flow, and even the lower drain port with the top two. As you would not be using the elements at all, you could remove them and use the two top inlet and outlet, along with the relief port with the relief removed, and the bottom tapping. If the electric elements are removed, there is no need for the T&P valve, as there is no heating source to remove, that is in the boiler. Using the two electric element ports alone might cause a short-circuit during flow, maybe not.
+++I don't think I'm following you. The ports on the top of the water heater are 1". I thought I would just be using two of the ports on the water heater (one for the boiler output and one for flow back to the boiler). So, I'm not sure why you're recommending using the lower element port as well as the 2 upper ports, etc.Are you saying to tee the 2" pipe from the boiler as well as the pipe back to the boiler so each one has 2 penetrations in the water heater for extra flow?
