Mini split btu vs. electric baseboard btu
if I have a room with a 2000 watt electric baseboard heater and 1kw=3412btu’s, then I would have about 6824 Btus in that room, correct? Now that would be if the baseboard unit ran for an entire hour straight? Which it never does, but I would assume I could heat that room with a 9k head easily as the Mitsubishi’s systems put out about 10,600 at 5F and fall off a little from there down to -13. I would be able to heat the room with a 6k head, but I think it would run out of heat around 0 or so. I’ve done a few manual J’s (or tried to at least) as I consistently keep getting different numbers from every HvAC tech I call.
Also, if I put in a mxz3c30k hyper heat, which puts out 28600btus at 5F, then all 3 heads share that load, or if 2 heads are calling for heat and 1 is not, then do the two get a bigger share of what they could use? I’ve seen that if I marry three 12k heads to the 30k hyper heat, the submittal sheet shows they put out 9500btu’s. At what temp is that? 5F? Again, I think of two heads are calling for more heat, then they may get 11,000 and the other one could be 6500?
