Introducing heat-pump and solar water heaters to the US residential market and a tax credit for solar installations offers energy saving and direct economic benefits. Energy savings are estimated for ten regions of the USA, as well as for the country as a whole, over the period 1977 to 2000. Changes in annual fuel bills and capital costs for water heaters are also computed. Comparisons suggest that heat-pump water heaters are likely to offer much larger benefits than solar heaters, even with tax credits. This is because heat pumps provide the same electricity savings (about 50%), but at a much lower capital cost. 31 references, 8 figures, 4 tables.
