Best price water to water cooled heat pumps for sale

GHP30/B-DNNHE, with internal auto start emersion heater by the outside temperature, designed and tested by European standard EN14511, approved and tested by TUV china branch. Characterized by its high COP, competitive price and perfect quality.
 

To heat (or cool) your home with geothermal energy you need a heat pump unit (In the same way that your fridge uses refrigerant to extract heat from the inside, keeping a ground source heat pump extracts heat from the ground, and uses it to heat your home.), a loop of refrigerant filled piping buried outside, ductwork inside, a circulating pump, and other mechanical and electrical items which complete the system. Though initially expensive, ground source heat pumps are very cheap to run and maintain, and they are also very efficient and environmentally friendly.  

 

HISEER geothermal ground source heat pump adopts the following world famous parts:

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

 

The top 15 meters of the Earth's surface maintains a relatively constant temperature of approximately 12 degrees Centigrade. This energy can be used to heat buildings indirectly. Pipe is buried in the ground, either in a borehole or a horizontal trench. The pipe is usually a closed circuit and is filled with a mixture of water and antifreeze, which is pumped round the pipe, absorbing heat from the ground. In winter the ground is warmer than the air and buildings above. The anti-freeze mixture absorbs heat from the ground, which is then concentrated and transferred to the buildings. This heat can be used to heat domestic water and a low temperature heating system such as underfloor heating.

 

Underground collectors can be installed in two ways. Either as a horizontal collector, set in a depth of 1.5 to 2 m under ground level or as a vertical one set in one or more boreholes. Bore-holes being significantly deeper than pipes in shallow trenches are less susceptible to seasonal temperature changes and the energy available for the heat pump is more even throughout the heating season. When compared to an installation using horizontal collectors, vertical bore-holes and their collectors experience lower seasonal temperature changes and earth-water heat pumps can achieve higher COP’s.
