Product Description

The Water Source Heat Pump absorbs energy from underground and then transfers it into water. It can also take the energy from the water and transfer it to the ground. It can supply sanitary hot water for bathroom or central heating / cooling to under floor heating pipes or Fan Coil. The ultra quiet design makes the whole compressor and Heat Pump System on a floating plate, leads to a compete isolation from the heat pump bottom, and reduce vibration and noise at the most extent. Amrta new water to water heat pump is ideal for indoor installation.These units have got CE approval.

Application areas
● Offices, Hotels, Hospitals, Schools
● Industry
● Administration
● Commercial buildings
