Our take in 30 seconds
Best for: cold and very cold climatesStrengths
- Keeps 100% of its heat at 5°F, so backup heat rarely runs
- Heating efficiency (HSPF2 10) beats 77% of models
- Variable-speed compressor: quieter, steadier temperatures and better humidity control
- Uses newer, lower-impact R-454B refrigerant
Good to know
- Efficiency depends on the indoor unit: SEER2 ranges 15.2–19, so ask which pairing you're quoted

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 BOVB-36MTB-M19E at the three ENERGY STAR test temperatures (cooling capacity is 36,400 BTU/h for reference).
Retention at 17°F: 100% · at 5°F: 100%. Learn how to use these numbers in our cold-climate guide.
