Heating capacity as it gets colder
A heat pump's output falls as outdoor temperature drops. This is the certified heat output of the Lennox EL19KPV-048-230A** at the three ENERGY STAR test temperatures (cooling capacity is 48,000 BTU/h for reference).
Retention at 17°F: 64% · at 5°F: 63%. Learn how to use these numbers in our cold-climate guide.

Frequently asked questions
How much does the Lennox EL19KPV-048-230A** cost to run per year?
At the U.S. average residential electricity price of 18.16¢/kWh and typical national heating and cooling hours, we estimate about $2,278 per year ($1,679 heating, $599 cooling). It ranges from about $1,293 in Louisiana to $5,209 in Maine.
Does the Lennox EL19KPV-048-230A** work in cold weather?
It is not ENERGY STAR cold-climate certified. It delivers 32,800 BTU/h at 5°F (63% of its 47°F capacity), so in very cold climates expect more reliance on backup heat.
What size is the Lennox EL19KPV-048-230A**?
It is rated at 48,000 BTU/h of cooling, roughly 4 tons, and 52,000 BTU/h of heating at 47°F. Proper sizing should be confirmed with a Manual J load calculation.
