Biggest thing is to make sure you have no leaks. Not a fan of those units. I am not sure how they get away with just anyone buying them. I need to have a refrigerant license from the epa to buy charged equipment from distributor. Have a recovery machine and tanks to recover refrigerant. If not I can face a fine and possible jail time if not in compliance. End rant.
Those Mr. Cool units are not bad. They work well.

It’s no different than buying a window a/c unit, it’s all sealed and ready to go, you just have to connect a few lines and turn on some valves.

I have a fairly complicated mini-split system.
Two 36,000 btu outdoor units and seven heads in the house. Al the piping sets are run into the basement and then up through closets to interior walls with two units on the high walls of two rooms with a vaulted ceiling. The condensate drain lines follow the same routing with most of them going to the sump pit in my basement.
This system works very well and is quite efficient at cooling and heating.
I use it for heating untill it gets down to were I don't have to use the "window stat" much then I'll start the coal going.
My coal only covers about half of the house area. This year the mini-splits will be covering much of the heat that the boiler usually did till we get down under 30F. They are supposedly 250-280% efficient compared to resistance electric heat.
With my total KWH cost of $0.12 to $0.14 per and coal at $300 per ton;
If I consider my insert to be 75% efficent per the calculator on this site coal is $1600 per million btu,
and my mini-split heat we be $1641 per million.
While oil at $5.50 and 75% efficiency will run me $5287.00 per million.
I did manage to lock in oil at $4.04 per gallon by going with my brother and locking in several thousand gallons that we have to take delivery of before November, unfortunately that will be easy to do on the farm.
Even at $4.04 thats over $3800 per million.

I think you forgot the decimal points. At my coal prices my coal heat is roughly $10.00 per million BTUs. Nat Gas is less than $10 right now.LouNY wrote: ↑Sun. May. 29, 2022 10:20 amWith my total KWH cost of $0.12 to $0.14 per and coal at $300 per ton;

$1600 for 1 million BTUs of coal heat? That may be total seasonal cost for multiple millions of BTUs but certainly not for 1MBTs of heat, or per million BTUs . What am i missing?

The calc provides $/100 million BTUs .. one is free to convert that value to others .. which is what the poster did.
It can lead to confusion noting the source is the forum's calculator. In this case the poster provided correct values and units. Usually when I make conversions I show my work (thanks Mr. 5th grade "show your work!" math teacher) in the conversions. Its not required. Math is the best subject as you can always prove the teacher wrong if they are wrong. kek
