Tiny home heat pump (Mitsubishi or Fujitsu) for a mostly empty house
I am in the process of renovating a 1-level 470 sq ft basement walkout condo in Kittery, ME. It has two floors above it. I’ve consulted a contractor, and don’t agree with their suggestion for a mini split. So, I’ve started doing research!
They suggest the Mitsubishi MSZ-FH15NA (they did not do a Manual-J, so I’m not sure what it’s based on.) Based on what I have found, there doesn’t seem to be a reason to go this big. I’m totally redoing the space with pretty energy efficient materials including 1″ insulation in the slab. It should be a pretty tight space with a low load. I’m not the type to turn the heat on very high…in fact, I travel about 3 weeks out of every month, so the heat will be kept around 55º.
I’m thinking more along the lines of either the Mitsubishi MSZ-FH09NA or the Fujitsu 9RLS3H. The bonus with the Mits is the ability to control it with my iPhone from when I’m gone (peace of mind since there is no other heat source.) But the Fujitsu seems to have a better warranty, I’ve had one in the past and loved it, and has better efficiency.
Hoping to get any input. Thank you!!!
