air-to-water heat pumps are traditional air source heat pumps, which means they
do not require a ground return to collect heat. Instead, they use outdoor air
as a heat source in winter and a radiator in summer. There is no outdoor heat
collection system, and the installation cost is low.
Water Heat Pump
air-to-water heat pumps (LM series) heat water through a circulating fan coil
to generate radiant floor heat and cool water for air conditioning. While air
source heat pumps are sometimes known for their poor performance in severe cold
weather, we have made several modifications to air source heat pumps to improve
their performance, even in harsh winters.
heat pump features an oversized outdoor unit that provides excellent heating in
cooler outdoor temperatures. It is also equipped with smart defrost logic that
minimizes the energy required to defrost the outdoor coil. Finally, the
compressor portion of the machine is located in your home, providing protection
from harsh outdoor weather.
in sizes from 2 to 6 nominal tons, the LM series is suitable for whole home
applications and operates in temperatures as low as -7°F (-21.7°C) where backup
heating is required.
