Série Merit® | ML14KP1 Lennox Heat Pump
Why choose a heat pump?
Exceptional energy efficiency
Because they transfer heat rather than produce it, heat pumps use much less energy than traditional heating or cooling systems.
Dual function: heating and air conditioning
They provide year-round comfort, warming in winter (down to around -5°C) and cooling in summer.
Ideal solution as a secondary system
In Ontario, heat pumps are often used as a complement to a central system, helping to reduce overall energy consumption.
Flexible and adaptable installation
They can be integrated into an existing ducted system, a radiant system or even operate independently without ducts (wall-mounted heat pumps).
