TOSOT mini splits

TOSOT is GREE's sibling brand - same parent manufacturer, different badge - and our coverage of it is narrow and specific: 7 systems, all multi-zone, in a single line called Multi Ultra Heat. There are no TOSOT single-zone systems in our catalog.

What is here is good. Multi Ultra Heat spans 18,000-55,000 BTU at SEER2 21 with rated heating to -22F, and 55,000 BTU is among the largest multi-zone capacities we track. Professionally installed, current-generation R-32.

Who should buy TOSOT: someone hiring an installer for a multi-room job who wants GREE-family engineering with genuine cold capability, especially at the large end. Who should skip it: anyone conditioning a single room - we have no TOSOT single-zone data, and GREE's own catalog covers that ground far more thoroughly.

What to know about TOSOT

  • TOSOT and GREE share a manufacturer. If you are cross-shopping, you may be comparing closely related hardware under two badges. Our GREE hub covers eleven lines and is the better starting point for understanding the family.
  • -22F across the whole line is a genuine strength - many competitors' large multi-zone condensers give up cold capability as capacity rises, and this one does not.
  • SEER2 21 flat across the range is respectable rather than exceptional. You are buying capacity and cold capability, not the efficiency ceiling.
  • Our TOSOT coverage is thin by our own standard, and we would rather say so than imply a complete picture. If you need single-zone TOSOT data, we do not have it yet.

TOSOT multi-zone options

Multi Ultra Heat is the whole TOSOT catalog here: 18,000-55,000 BTU, SEER2 21, rated to -22F throughout.

The 55,000 BTU condenser is worth flagging - very few multi-zone systems we track reach that capacity and hold a -22F rating. If you are heating a whole house from one outdoor unit in a cold climate, this is a short list and TOSOT is on it.

For two rooms, price two single-zone systems first - single-zone avoids the part-load penalty and a failure only takes out one room. That would mean looking at GREE rather than TOSOT.
