I have one in my place up north, they are awesome for A/C . They make heat down to -25, but they lose efficiency as the temp drops. My unit is cheaper than gas above -8, and cheaper than resistance heat a to -15c.Mini-splits...
We are looking at installing a four zone. The house is hot water heat and we want AC and heat pump to reduce boiler use. Any thoughts beyond what was covered in this thread before. Does anyone here install or has a recommendation (PM me on this one)?
At -20 it can’t make enough heat to be a primary source, the house loses heat faster than the heat pump can make it.
In Southern Ontario we don’t get many days below -10, so the economics are a lot better than Timmins where the low is below -20 for 20hrs a day from mid dec to mid march.
