Last week I wrote about ["hybrid" water heaters](http://www.greenbuildingadvisor.com/blogs/dept/energy-solutions/hybrid-water-heaters), a relatively new type of water heater that includes features of both storage and tankless models. This week I'll cover another type of water heater that is also (confusingly) referred to as "hybrid": heat-pump water heaters. These produce over twice as much hot water for each unit of electricity consumed as any other type of electric water heater (storage or tankless).
