Features of your Air to water heat pump

• Quick Heating by TDM Technology

Floor heating is well known as the optimal heating option for indoor thermal comfort.
However, it takes 4~8 hours to heat up the room after it is turned on. Samsung EHS TDM
technology quickens that process by blowing hot air along with floor heating to warm up
the room.

• Integrated Heating & Cooling System at a Lower Cost

Time Division Multi (TDM), a smart alternating operation between air-to-water and
air to air, enables one outdoor unit to operate for both functionalities resulting in lower
product cost and space saving.

• Running Costs-Reduction of Up to 33.3%

Samsung EHS, known for its world class efficiency (11kW floor heating system with COP
of 4.55), can reduce 33.3% of your running costs as compared to a gas boiler.

• Price and Space Reduction of Up to 50%

With an all-in-one outdoor unit capable of both air-to-water and air-to-air functions,
Samsung EHS saves you in terms of the low initial purchase price & installation fee as well
as the space needed for an extra outdoor unit.

• High Performance at Low Temperature

Samsung EHS is made up of an inverter compressor optimally operated according to
the outdoor temperature, offering heating performance of 90% at -10°C and reliable frost
protection at -20°C.

AVAILABLE MODE

Under the installation of both A2A(Air-To-Air type air conditioner) and A2W(Air-To-Water type hydro unit)
at the same time, if our system operates only the heating mode of Air-to-Water Heat Pump,
actual performance of our Air-to-Water Heat Pump may be reduced a little as compared with its rated
performance. Because the part of the circulating refrigerant amount is bypassed into A2A type indoor
units during A2W’s normal operation.
