So my radiant heat barrier arrived & was (mostly) installed yesterday!

13. My resident hvac expert just left fof the afternoon

But can get info for you this evening or tomorrow.

I'll give you an eg of my setup. Living room, kitchen, small eating area, 20' hallway with 3brs & 1 bath, dining room (largely closed off for efficiency).

My unit is on wall above couch, pointing down hallway to brs & bath, but a bit off center.

I keep my house super cold. In this extremely hot weather, I close doorway to hall to minimize power use during day.

My power draw is 400-600 watts generally & last month's electric portion of utility bill was $70, including a 40% rate increase!

Keep in mind, systems are generally heat or ac optimized. I chose ac because heat is deadly to me. (Heat sensitivity disorder.)

We put foil radiant heat barrier up in attic (~$130 / 1k ft). Like putting an umbrella or shade tree over your home. Best $130 I've ever spent. You only need a staple gun to install. You musg leave air pocket between roof & foil for it to work. So, make it sort of billowy.

If you are looking at a minisplit, only look at Mitsubishi. They are hands down the very best. The units come with a fully charged line set, so you can do install yourself. 👍

So sorry you are having problems with your unit!
