Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Bosch BOVA-60RXB-M15S at the three ENERGY STAR test temperatures (cooling capacity is 55,000 BTU/h for reference).
Retention at 17°F: 71% · at 5°F: 71%. Learn how to use these numbers in our cold-climate guide.

Same equipment sold under other brands
These listings share the same certifying manufacturer (Bosch Thermotechnology Corporation) and identical certified capacities and efficiency ratings, so they are almost certainly the same hardware with a different badge. If you get quotes for any of them, you are comparing installation price and warranty, not equipment. How rebadging works.
