Make sure it will still heat at your design temps. many stop heating at 0 or -13.
Yes, I believe this one heats down to -13... Thanks!Make sure it will still heat at your design temps. many stop heating at 0 or -13.
no way to tell without doing a load calc. For $50 you could try something like HVAC Calc and get a good idea of what the load is. Could save you a few $100 on equipment.Thanks in advance for any advice, tips, or opinions! :thumbsup: Also, does 12K BTU sound about right?
The high wall indoor boxes are the most efficient (COP/SEER) judging from the manufacturers' numbers. The short-ducted and ceiling boxes are just not up to the same level for some reason.... therefore pretty darned efficient.
This is not an issue for the OP, but the outdoor/compressor sections for multiple indoor equipment can't run a single indoor unit to as low a level as the 1:1 systems according to the data I have seen. They are just bigger so it is inherent. That might be something to keep in mind when installing a system with one single and a multi and you can choose where to put the single system -- where it might be running at low levels a lot of the time. (Think bedroom at night.)The inverter will allow it to pace itself for inside load conditions.
In a ceiling cassette?Wow, that is huge considering that other brands have residential equipment as low as 5000 and 6000.
