In my part of the country our electric is 10 cents per KwH and I have no NG service or propane. My little electric wall heaters are fine but pretty noisy and expensive to run as a backup heat source. Also they only provide heat and are generally considered ghetto and a cheap way to heat a home, so poor for resale. I have no ductwork in the home. The home is single story on a crawlspace, 1700 SF with 8 foot ceilings, it is only like 26' wide and 60 some feet long with upgraded insulation and windows. I've been considering these ductless heat pumps to heat and cool my home. Our climate is moderate with most of the year around 50 degrees out. We get some 100 degree days and some days in the teens. Air source heat pumps are very common in this climate. I would expect that the core of the home would be heated with the heat pump and the remote rooms would keep their little heaters which should greatly simplify the installation. Does anyone have any experience with these things? The installation looks simple. Are they noisy, expensive, dependable, ? Our local utility is offering a fat rebate for the installation and maybe OBAMA's credit too. Does the condensate line run back to the outdoor unit as the vendors imply?
