Best forBuyers with a 230V circuit who want more efficiency and a lower heating floor than Della's 115V units, and are comfortable doing a flare-and-vacuum install.
Overview
The Vario is Della's 230V step up from the Motto and JPB: 23 SEER2 and 9.5 HSPF2 on its AHRI certificate, R-454B refrigerant, and a published heating range down to -4°F, against 5°F on the 115V models. That makes it the cheapest Della that clears the -4°F line this site uses for cold-climate units. The -4°F figure is an operating limit, not a capacity rating. The Vario is not on NEEP's cold-climate list, and Della publishes no heating output below 47°F, so how much heat it delivers at 5°F is unknown. Install is the usual Della job: flare connections, a vacuum pump and a leak test, with lifetime parts coverage only if you register within 100 days. Little owner feedback exists for this model yet. What is known about Della generally (value for money, quiet heads, slow support when a board fails) is covered on the Motto page.
- 23 SEER2 / 9.5 HSPF2 (AHRI certified)
- Rated to operate to -4°F
- Not on the NEEP cold-climate list
Cold-weather output
No current listing on NEEP's cold-climate heat pump list. Della rates it to keep running down to -4°F; without a listing there's no certified 5°F capacity figure to check that claim against.
