tankless water heater

Since I’m currently living as an expatriate in Sweden, I have been watching the stimulus package action from afar — with envy! Details are now emerging on how U.S. homeowners can take advantage of tax credits for energy-efficient improvements: a 30 percent rebate, up to a max of $1,500 for most projects. (The old federal tax credit was 10 percent up to a max of $500.)

Tankless water heaters are getting a lot of buzz these days. After all, they can reduce a household’s water-heating energy use by 20-50 percent. And that’s no chump change: Water heating counts for about a third of a house’s total energy usage.
