If you were not planning on selling it within a year or two, I would suggest a ductless mini split as they are the ideal item for additions. Since you are planning on selling it, I would just try and utilize the existing ductwork for the main hvac as best as possible and use space heaters or something of the like to get thru a winter. Installing a wood stove or a ductless mini split or any other sort of "system" would be cost prohibitive.
If you are going to be there for 2-3 years(or more) , I'd look at a small mini split heat pump from mitsubishi, fujitsu or daikin. If you are halfway handy you can install it yourself and buy them online at places like ductless depot or go ductless.com type places. It's rather easy.
I'm a big fan of ductless mini splits and I think they are very UNDER used here in the states. With new homes (especially sips and icf's) they are ideal. However, in your situation with an already existing hvac system it would be much wiser to utilize your existing system, especially with your short term stay planned.
You can go to youtube and see some videos of how ductless systems are installed (usually in 1 day or less) and now their registers look like tradiotional american registers.
Good luck! |
