I have been researching the best way to heat and cool my house for quite a while now. One thing that has always bothered me was the fact that a system has to be sized just right to work properly. I plan to finish my basement and possibly add other square footage in other areas. Since I'm not sure exactly what my house will look like in the end state and don't like the idea of multple systems it has been sort of a show stopper for me. I've often wondered why at work we add and delete space all of the time without the sizing issues. Since I work in a very large building we have a chiller. I happened upon the website for Multi-Aqua today and this sounds like it may be an option for me.
What is the downside of this type of unit? I guess for one thing it may be noisy. It looks like you would have to have a wall unit in each and in some cases may be unsightly. Seems that they sell some fan/coils that can be tucked away also.
Does anyone use these in residential applications? Sounds interesting? I love the flexibility.
