    Have recently installed a condensing

    Have recently installed a condensing combi boiler, which has, i believe, reduced not only my heating bills but also my carbon footprint i also felt good about ignoring the "hot water preheat" option but now i find that the hot water tap must be left running for a minute or more before hot water arrives which is the greener course of action: wasting water or using the energy required to operate the "hot water preheat" option? Having a good boiler makes a big difference in a household, especially.
