Deciding on a Water Heater - GreenBuildingAdvisor

As we build more energy-efficient houses, particularly when we go to extremes with insulation and air tightness, as with Passivhaus projects, water heating becomes a larger and larger share of overall energy consumption. In fact, with some of these ultra-efficient homes, annual energy use for water heating now exceeds that for space heating — even in cold climates. So, it makes increasing sense to focus a lot of attention on water heating. What are the options, and what makes the most sense when we’re trying to create a highly energy-efficient house?
