How to reach the high pressure water with a hot water heater?

I try to run 3 / 4 "PEX pipe throughout a house maintain water pressure. All water heater tankless propane water have only 1 / 2 "connections and pipes running through them. I found a hot water tank without a 3 / 4 "connections, but it reduced to 1 / 2" and when I asked the ebay seller, if reduced 1 / 2 "because I needed 3 / 4", he told me how very offensive that I asked was impossible and empty the water tank too quickly. However, the aircraft would not and should not allow the flow that I face. The bathtub faucet lets about 15 L / Min. Should I install only 1 / 2 "pipe, or should I use double and two water heaters to compensate for the loss of water pressure in this way? Thank you

just to let you know that you are using; pressure and flow; distinction, and are not. So it's a bit confusing.then you say that the flow is limited by the tap in any way. So did you have a problem. before installing or is it new?
