Cost Saving Heating and Cooling System air to water heat pumps

HISEER AW20-DNNNE, heating & cooling air source heat pump, heats & cools your house as well as offers domestic hot water, characterized by perfect performance, eco friendly refrigerant, high quality and competitive price.

HISEER heat pumps adopt the following world famous parts:

Siemens controller Hitachi scroll compressor SWEP or GEA plate type heat exchanger Emersion thermal expansion valve Emersion dry filter Schneider A/C contactor Honeywell R410a refrigeration

Air source heat pumps use the refrigeration process to transfer low grade energy from the air outside into high grade energy used for heating and domestic hot water. Even at temperatures as low as -20˚C, an air source heat pump can supply significantly more energy than it uses – and with no local C02 emissions, it helps reduce impact on the environment.

Heat pumps are measured by their coefficient of performance (COP). The COP for air source heat pumps is very similar to that for ground source heat pumps at approximately 2-4. With a COP for instance of 4, 4 units of heat are produced for every 1 unit of electricity consumed. (The three free units of heating were extracted from the outside air). Even with ambient air temperatures of -10 to -15 degrees Celsius, an air source heat pump can extract useful heat (i.e. > 1 unit of heat generated per unit of electricity consumed).

Advantages:

Easy installation Utilization all the year round for heating, cooling as well as hot water Low investment costs with high quality Silent operation Reducing your carbon emission Enjoying your green life by installing HISEER heat pumps Reducing your heating and cooling bill with high efficiency HISEER heat pumps
