This, exactly. When we redid our bathroom, we went from "immersion tank" hot water with about three metres of pressure behind it, to central heating in a closed system, where both hot and cold have the exact same pressure, about thirty metres head. Went from being basically impossible to have a shower, to being an absolute pleasure where nearly the entire range of the tap gives a useful temperature, and it's got a right blast of pressure behind it too.

Another alternative would be an electric shower - since you're just heating up cold water, the pressure is "always the same". They tend to be a bit pathetic and crap, tho.
