New builds in the last 10-15 years now typically have “unvented” systems - you still have the combi boiler unit but instead of heating on demand, it circulates hot water through a coil in a mains-pressurised insulated tank. The advantage of this is that cold and hot water are both at the same pressure, and you don’t have to wait for the combi to kick in once you open the tap.
