About The Lennox EL21KLV-036-230
Description
The Lennox EL21KLV-036-230 is a 3 ton (36,000 BTU) Elite Series cold climate heat pump with a variable-capacity inverter compressor and R-454B refrigerant. Depending on the indoor unit, it's AHRI-rated up to 20 SEER2 and up to 10.4 HSPF2.
Key specs
- Efficiency: 14.3 to 20 SEER2 and 8.5 to 10.4 HSPF2 with our Lennox indoor units
- Operating range: heats down to -15°F and cools down to 0°F outdoor air
- Cold weather heat: 23,800 BTU at 5°F with the CBK45UHVT-042-230-71 air handler (AHRI)
- Sound rating: 62 to 72 dBA
- Line connections: 3/8-inch liquid and 7/8-inch suction, sweat
Reading the model number
EL is Lennox's Elite line, and 21 is the nominal SEER2 class for the EL21KLV series. K is R-454B, L is a cold climate heat pump, V is the variable-capacity compressor, 036 is 3 tons, and 230 is 208/230V single-phase. The characters after 230 on the unit label are Lennox revision codes. The AHRI Directory lists it as EL21KLV-036-230A**.
What it pairs with
The AHRI Directory lists it with Lennox CBK45UHET, CBK45UHVT, and CBK47UHET air handlers, and with CK40CT, CK40DT, CK40HT, and CK40UT coils on Lennox gas furnaces for dual fuel. The best match we carry is the CBK45UHVT-042-230-71 air handler, at 20 SEER2 and 9 HSPF2. For heating, a CK40CT-30B-71 coil on an SL280UH090V36B furnace reaches 10.4 HSPF2.
R-454B systems need a refrigerant detection sensor at the indoor unit, so confirm your coil or air handler has one.
Sizing and fit
With a gas furnace, you need a dual-fuel thermostat or a zoning system with dual-fuel control. Size it from a Manual J load calculation, checking heat output at your local winter design temperature.
Warranty and registration
HVAC USA is an authorized Lennox reseller, and everything we sell is new factory equipment. Your full Lennox warranty applies when a licensed, manufacturer-certified contractor installs your system and registers it within 60 days.
