The standout number
COP 1.99 at 5°F — it keeps working efficiently when it's frigid.
The catch
A DIY-listed unit still needs a licensed pro for the refrigerant hookup, permit and warranty.

Frequently asked questions
Does the Senville SENA/12HF/OQ still heat in cold weather?
At 5°F it runs at a COP of 1.99, meaning it delivers 1.99 units of heat for every unit of electricity it uses. Its certified heating output at 5°F is 11,900 BTU per hour. It carries the ENERGY STAR Cold Climate designation.
What does the Senville SENA/12HF/OQ cost to run?
About $17.60 per MMBtu of delivered heat at the U.S. average electricity price, roughly 68% less than electric resistance heat. Your local electricity price changes the number — use our operating-cost calculator to run it with your rate.
What refrigerant does the Senville SENA/12HF/OQ use?
R-410A, which has a global-warming potential (GWP) of about 2,088. R-410A is being phased down for new equipment, so newer models increasingly ship with lower-GWP R-32 or R-454B.
Where can I buy the Senville SENA/12HF/OQ?
It's listed for sale online at Amazon for about $800. A licensed pro should still handle the refrigerant hookup, permit and warranty.
Sources. Performance ratings from the AHRI Directory (cited by reference number 210372990; not a verbatim mirror) and ENERGY STAR certification data. Operating-cost ($/MMBtu), savings and percentile figures are computed by Verified HVAC Data from published ratings and EIA U.S. average energy prices — see our methodology. Refrigerant GWP is the IPCC value for that refrigerant. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
